D01 - Paint and Related Coatings, Materials, and Applications

SIGNIFICANCE AND USE
5.1 Many physical and appearance properties of the finished coating are affected by the film thickness. Film thickness can affect the color, gloss, surface profile, adhesion, flexibility, impact resistance and hardness of the coating. The fit of pieces assembled after coating can be affected when film thickness is not within tolerance. Therefore coatings must be applied within certain minimum and maximum film thickness specifications to optimize their intended use.  
5.2 All procedures involve taking measurements of applied coating powders in the pre-cured, pre-gelled state to help insure correct cured film thickness. This enables the application system to be set up and fine-tuned prior to the curing process. In turn, this will reduce the amount of scrap and over-spray. Accurate predictions help avoid stripping and re-coating which can cause problems with adhesion and coating integrity.  
5.3 Measurements of cured powder coating thickness can be made using different methods depending upon the substrate. Non-destructive measurements over metal substrates can be made with magnetic and eddy current coating thickness gauges (see Practice D7091). Non-destructive measurements over non-metal substrates can be made with ultrasonic coating thickness gauges (see Test Method D6132). Destructive measurements over rigid substrates can be made with cross-sectioning instruments (see Practices D4138).
SCOPE
1.1 This practice describes the thickness measurement of dry coating powders applied to a variety of rigid substrates. Use of some of these procedures may require repair of the coating powder. This practice covers the use of portable instruments. It is intended to supplement the manufacturers’ instructions for their operation of the gauges and is not intended to replace them. It includes definitions of key terms, reference documents, the significance and use of the practice, and the advantages and limitations of the instruments.  
1.2 Three procedures are provided for measuring dry coating powder thickness:  
1.2.1 Procedure A—Using rigid metal notched (comb) gauges.  
1.2.2 Procedure B—Using magnetic or eddy current coating thickness gauges.  
1.2.3 Procedure C—Using non-contact ultrasonic powder thickness instruments.  
1.3 Coating powders generally diminish in thickness during the curing process. Some of these procedures therefore require a reduction factor be established to predict cured film thickness of powder coatings.  
1.4 Procedure A and Procedure B  
measure the thickness (height or depth) of the applied coating powders in the pre-cured, pre-gelled state. By comparing results to the measured cured powder thickness in the same location, a reduction factor can be determined and applied to future thickness measurements of the same coating powder.  
1.5 Procedure C  
results in a predicted thickness value of the cured state based on a calibration for typical coating powders. If the powder in question is not typical then an adjustment can be made to align gauge readings with the actual cured values as determined by other measurement methods.  
1.6 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.  
1.7 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.8 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

SIGNIFICANCE AND USE
3.1 Although chlorinated phenol-treated wood has become less common due to environmental concerns, repellent-treated wood is commonly specified in construction. This test method provides a means to verify the presence of a significant level of water repellent protection.
SCOPE
1.1 This test method covers simple qualitative field or laboratory tests to determine water repellency or the presence of chlorinated phenol2 preservative chemicals in wood products that are specified to be water repellent preservative treated.  
1.2 The values stated in SI units are to be regarded as standard. The values given in parentheses are for information only.  
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

SIGNIFICANCE AND USE
5.1 The ability of a coating to resist printing is important because its appearance is adversely affected if the smoothness of the coating film is altered by contact with another surface, particularly one with a texture. Interior paint systems, particularly gloss and semigloss on window sills and other horizontal surfaces, often have objects such as flower pots placed on them that may tend to leave a permanent impression. This tendency for a paint film to “print” is a function of the hardness of the coating, the pressure, temperature, humidity, and the duration of time that the object is in contact with the painted surface.
SCOPE
1.1 This test method covers an accelerated procedure for evaluating the print resistance of architectural paints. It differs from print resistance Test Method D2091 in that the latter is concerned with lacquer finishes under packaging, shipping, and warehousing conditions, whereas this test method is concerned with decorative coatings undergoing random on-site pressure contact.  
Note 1: Printing should not be confused with blocking, which is measured in Test Method D4946. The former relates to the indentation of a surface, and the latter, the sticking together of two surfaces.  
1.2 The values stated in SI units are to be regarded as standard. The values given in parentheses after SI units are provided for information only and are not considered standard.  
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

SIGNIFICANCE AND USE
5.1 As the brush drag of a paint increases, any natural tendency on the part of the painter to overspread the paint is reduced. When all other factors are held constant, increased brush drag will result in greater film thickness with consequent improvement in durability and hiding. Conversely, sometimes it might be preferred to have a lesser degree of brush drag for easier application (that is, the amount of time and effort in applying a paint to a specific area is reduced with a lesser degree of brush drag).  
5.2 This test method provides a standardized brushout procedure for the evaluation of brush drag as an alternative to customary informal ad hoc procedures. Its objective is to maximize the reliability and precision with which this characteristic may be determined.
Note 1: The brush drag of paints is directly related to their high-shear viscosity. There is generally good rank order agreement between results obtained by this method and Test Method D4287. The sensitivity of this brushout method has been found sufficient to distinguish between brushability corresponding to high-shear viscosity differences not lower than 0.3 poise (0.03 Pa.s). Round robin data show that rank order agreement between the brushout and viscometric methods is poor when both latex and solvent-borne paints are part of the same comparison group. This is the result of these two paint types having markedly different rheological properties that affect the relative perception of brush drag.3
SCOPE
1.1 This test method is a standardized brushout procedure for comparing the brush drag of architectural type solvent-borne paints.  
1.2 With slight modifications this test method is also applicable to solvent-borne paints.  
1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.  
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

ABSTRACT
This practice establishes the standard procedures for evaluating the resistance of pre-stressed prepainted metal panels to cracking and loss of adhesion, or both, after accelerated aging by boiling water. This method shall require the use of boiling water bath, 10x magnifier, Scotch #610 adhesive tape or its equivalent, and deionized or other water as reagent.
SIGNIFICANCE AND USE
3.1 Prepainted metal is supplied as a painted coil, and it is fabricated into a finished part. The fabrication process induces stress to the paint system. To determine if this stress will lead to a failure in service, it is common to immerse the stressed sample in boiling water. If no failure occurs (see 7.4) after exposure to boiling water, it is very unlikely that a failure will occur in the field.
SCOPE
1.1 This practice can be used to evaluate the resistance of a pre-stressed prepainted metal panel to cracking and loss of adhesion, or both, after accelerated aging by boiling water. Most coil coated products are formed and bent into specific shapes to produce a final product. These operations introduce stresses, which may be relieved by cracking of the coating after aging.  
1.2 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.3 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

SIGNIFICANCE AND USE
5.1 As a base for calibration adjustment or accuracy verification of dry film coating thickness measuring instruments.  
5.2 The dry film thickness of coatings on wood or wood-based products is specified in written product warranties for proper decorative and protective performance of coatings on wood or wood-based products.  
5.3 The minimum and maximum dry film thickness of coatings is recommended by coating companies for satisfactory decorative and protective performance on wood or wood-based products.  
5.4 The average dry film thickness of coatings on wood or wood-based material may be used by manufacturing companies to estimate the theoretical cost of applied coatings.  
5.5 The ratio of minimum to maximum dry film thickness on textured products is used as an indication of coating uniformity.  
5.6 Specific coated product requirements may dictate certain film thickness determinations to be made. Agreement between buyer and seller may be advisable to accommodate product needs relative to dry film thickness.
SCOPE
1.1 This test method covers the measurement of dry film thickness of coatings applied to a smooth, textured or curved rigid substrate of wood or a wood-based product.  
1.2 This test method covers the preparation of wood or wood-based specimens for the purpose of microscopic measurement of dry film thickness.  
1.3 This test method suggests an analysis of dry film thickness of coatings on wood or wood-based products using a microscopic measurement.  
1.4 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined.  
1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

SIGNIFICANCE AND USE
4.1 This test method is the procedure of choice for determining volatiles in coatings for the purpose of calculating the volatile organic content in coatings under specified test conditions. The weight percent solids content (nonvolatile matter) may be determined by difference. This information is useful to the paint producer and user and to environmental interests for determining the volatiles emitted by coatings.
SCOPE
1.1 This test method describes a procedure for the determination of the weight percent volatile content of solventborne and waterborne coatings. Test specimens are heated at 110 °C ± 5 °C for 60 min.  
Note 1: The coatings used in these round-robin studies represented air-dried, air-dried oxidizing, heat-cured baking systems, and also included multicomponent paint systems.  
1.2 Sixty minutes at 110 °C ± 5 °C is a general purpose test method based on the precision obtained with both solventborne and waterborne coatings (see Section 9).  
1.3 This test method is viable for coatings wherein one or more parts may, at ambient conditions, contain liquid coreactants that are volatile until a chemical reaction has occurred with another component of the multi-package system.  
Note 2: Committee D01 has run round-robin studies on volatiles of multicomponent paint systems. The only change in procedure is to premix the weighed components in the correct proportions and allow the specimens to stand at room temperature for 1 h prior to placing them into the oven.  
1.4 Test Method D5095 for Determination of the Nonvolatile Content in Silanes, Siloxanes and Silane-Siloxane Blends Used in Masonry Water Repellent Treatments is the standard method for nonvolatile content of these types of materials.  
1.5 Test Methods D5403 for Volatile Content of Radiation Curable Materials is the standard method for determining nonvolatile content of radiation curable coatings, inks and adhesives.  
1.6 Test Method D6419 for Volatile Content of Sheet-Fed and Coldset Web Offset Printing Inks is the method of choice for these types of printing inks.  
1.7 This test method may not be applicable to all types of coatings. Other procedures may be substituted with mutual agreement between the producer and the user.  
Note 3: If unusual decomposition or degradation of the specimen occurs during heating, the actual time and temperature used to cure the coating in practice may be substituted for the time and temperature specified in this test method, subject to mutual agreement between the producer and the user. The U.S. EPA Reference Method 24 specifies 110 °C ± 5 °C for 1 h for coatings.
Note 4: Practice D3960 for Determining Volatile Organic Compound (VOC) Content of Paints and Related Coatings describes procedures and calculations and provides guidance on selecting test methods to determine VOC content of solventborne and waterborne coatings.  
1.8 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.  
1.9 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.10 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

SIGNIFICANCE AND USE
5.1 Contrast ratio at a specified film thickness is a useful hiding power parameter for production control and purchasing specifications.  
5.2 The greater the hiding power, the less coating is required per unit area to obtain adequate hiding. Knowledge of hiding power is therefore important in regard to coating costs and for comparing coating value.
SCOPE
1.1 These test methods determine and report the hiding power of a powder coating with respect to two parameters:  
1.1.1 Test Method A—Contrast Ratio at a given film thickness  
1.1.2 Test Method B—Film thickness at 0.98 (98 %) contrast ratio.
Note 1: The measured parameters follow powder coating industry practice by measuring hiding power in relation to film thickness, rather than the “Spreading Rate” function employed in Test Methods D344 and D2805 and other hiding power test methods.
Note 2: Hiding power is photometrically defined as the spreading rate at 0.98 contrast ratio. See definitions of spreading rate and hiding power in Terminology D16, D2805, and the Paint and Coatings Testing Manual.
Note 3: The contrast ratio 0.98 is conventionally accepted in the coatings industry as representing “complete” hiding for reflectometric hiding power measurements. But visually, as well as photometrically, it is slightly less than complete.  
1.2 These test methods cover the determination of the hiding power of powder coatings applied by electrostatic spraying.  
1.3 These test methods determine hiding power by means of reflectometric and thickness gauge measurements. They are limited to coatings having a minimum CIE-Y reflectance of 15 %.  
1.4 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.  
1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

SIGNIFICANCE AND USE
5.1 This test method has found acceptance in the lithographic ink industry in predicting rheological behavior of a vehicle under press conditions caused by extrusion, shear-thinning rollers and dot gain recovery.  
5.2 This test method is restricted within the torque limitations and strain resolution of the rheometer used.  
5.3 Results may not be reproducible if the vehicle is not homogenous.
SCOPE
1.1 This test method covers the procedure for determining the viscoelastic properties of printing ink vehicles by measuring the G', G”, and tan delta using a controlled strain cone and plate oscillatory rheometer.  
1.2 This test method provides the flexibility of using several different types of rheometers to determine viscoelastic properties in ink vehicles.  
1.3 This test method is not intended for systems that are volatile at procedure temperatures as evaporation may occur effectively changing the percent solids before testing is finished and significantly altering the rheology.  
1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.  
1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

SIGNIFICANCE AND USE
4.1 Interior paint films often become soiled, especially near doorways, windows, and play areas, and frequently need to be cleaned by scrubbing. This test method covers the determination of the relative resistance of paints to erosion when scrubbed.  
4.2 The precision of scrub resistance measurements in absolute physical values, such as Test Methods D2486 (cycles-to-failure or this test method, microlitres per 100 cycles), is poor due to the relatively large effect of subtle and difficult-to-control variables in test conditions. The test method described herein minimizes this problem by using a standard calibration panel as an integral part of each scrubbing operation and relating its weight loss to that of the paint film under test to establish the latter's scrub resistance.
Note 1: The numerical scrub resistance values obtained by this test method are of significance only in relation to the specific calibration panel types with which the value is obtained. Thus, for example, a scrub resistance value of 83 with a Type X calibration panel would be reported as 83X.  
4.3 Results obtained by this test method do not necessarily represent the scrub resistance that might be determined if the test film is allowed to dry before testing appreciably longer than the seven-day period specified herein.  
4.4 Results obtained by this test method do not necessarily relate to ease of soil or stain removal (also referred to as “cleanability” or “cleansability”). To test for those characteristics use Test Methods D3450 and D4828.
FIG. 1 Alignment of Panels for Scrubbing
SCOPE
1.1 This test method covers an accelerated procedure for determining the resistance of paints to erosion caused by scrubbing. (Note: The term wet abrasion is sometimes used for scrubbing, and wet abrasion resistance or scrubbability for scrub resistance.) Although scrub resistance tests are intended primarily for interior coatings, they are sometimes used with exterior coatings as an additional measure of film performance.

SIGNIFICANCE AND USE
5.1 By following this test method, the particle size, particle size distribution and particle shape of particulates in liquid paint and pigment dispersions can be measured.  
5.2 Particle size, particle size distribution and particle shape have a great effect on the color, opacity and gloss of paints. Reproducing these characteristics is critical to the quality and performance of the paint produced.  
5.3 The dynamic imaging instrument is useful during manufacturing to detect oversize particles as well as the required size distribution of particles in order to provide quality and consistency from batch to batch.
SCOPE

Note 1: Shape is used to classify particles, droplets and bubbles and is not a reporting requirement.
Note 2: The term paint(s) as used in this document includes liquid paint and liquid pigmented coatings.  
1.1.1 Some paints may be too viscous to flow through the imaging instrument without dilution which may be used to help the paint flow as long as significant contamination is not introduced into the paint.

5.2 This test method has demonstrated utility for wood or wood based products ranging in thickness from approximately 6 mm to 25 mm (1/4 in. to 1 in.).  
5.3 Conditioning of substrate, coated sample preparation, application method, dry film thickness, cure conditions, and number of replicate specimens should be agreed upon between the purchaser and the supplier of the coating material.  
5.4 Such measurements are used as indicators or predictors of the anticipated performance of coated wood or wood based products during exterior exposure. They may be used for developmental evaluation of coatings, substrates, or both. They may also be useful for quality control or monitoring of the production of coated wood and wood based products.
SCOPE
1.1 This test method is intended to serve as a means for measurement of liquid water that passes through a wetted paint film, and which is subsequently absorbed and retained by the underlying wood or wood-based substrate. Alternative techniques for the use of the “Cobb Ring” apparatus are described.

SIGNIFICANCE AND USE
3.1 It is important to recognize that a brush can be a mixture of several chemically different filaments or bristles, or both, in several cross sections, thicknesses and lengths. The following procedures will be helpful in identifying brush composition.
SCOPE
1.1 This practice covers the dimensions, terminology, materials and characteristics generally considered of importance to those within, or dealing with paint brushes, and describes methods of determining these parameters. This practice is not meant to be a definitive analytical method to deformulate brushes.  
1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.  
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use.

1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

SIGNIFICANCE AND USE
4.1 Coated wood panel products must be stacked face to face or face to back during warehousing, packaging, and transportation without the coated finish sticking (blocking) and becoming damaged. This test method describes a laboratory means of evaluating conditions of blocking using factors of pressure, heat, time and moisture.  
4.2 Degrees of hardness or degrees of cure of organic coatings, or both, can be evaluated using a blocking test.  
4.3 The rate of volatile loss (drying speed) of organic coatings can be evaluated using a blocking test.  
4.4 The effectiveness of protective packaging materials (slip sheets) for organic coatings on wood substrates can be evaluated using a blocking test.
SCOPE
1.1 This test method covers the determination of the block resistance of organic coatings on wood and wood-based panel substrates. Block resistance is the ability of a coating to resist sticking to another surface and to resist any change in appearance when it is pressed against that surface for a prolonged period of time.  
1.2 General methods for determining block resistance are outlined in Sections 6 and 7. Variations inherent in user materials and procedures, however, may dictate adjustments to the general method to improve accuracy. Paragraphs 7.3 and 7.4 provide guidelines for tailoring the general procedure to a user's specific application. Paragraph 7.5 offers a rating methodology.  
1.3 Test Method D2091 should be used for the determination of print resistance or pressure mottling of organic coatings, particularly lacquers, applied to wood-based case goods such as furniture.  
1.4 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.

1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

SIGNIFICANCE AND USE
4.1 Breaks or holidays in a coating applied over steel exposes the substrate to a potential corrosion cell. When the steel is subjected to cathodic protection by the polarization of the steel via sacrificial anodes or impressed current, the exposed steel at the holiday becomes the cathode in the corrosion cell. When the electrolyte is neutral or slightly alkaline, hydroxyl ions form from the reduction of oxygen and, when paired with a suitable cation from the electrolyte, form an alkaline solution. Depending on the strength of this alkaline solution and the concentration of the alkaline compound, this alkalinity may disrupt the adhesion between the coating and the steel, disbonding the coating from the steel.  
4.2 Current density of the cathodic cell also can affect the degree of cathodic disbondment. The greater the current density generated by the concentration of electrons at the anode, the greater the number of hydroxyl ions formed, thus increasing the alkalinity available for disrupting the adhesion between the coating and the steel substrate. Likewise, the concentration of oxygen in the electrolyte will affect the concentration of hydroxyl ions formed at the cathode.  
4.3 For these reasons it is often useful to measure pH, oxygen, and current density when conducting a cathodic disbondment test.
SCOPE
1.1 These test methods apply to procedures for determining the degree of disbondment of a coating from a steel substrate when placed in contact with an electrolyte and a potential is applied to the steel. Specimens may include coated steel pipe or coated flat or curved steel plate. The coating applied to the steel substrate shall be non-metallic and shall not show flow characteristics at the test temperature.  
1.2 These test methods apply to specimens that are immersed in an electrolyte bath or specimens with an attached electrolyte cell at ambient room temperature, 21 °C to 25 °C (70 °F to 77 °F), conditions. If higher temperatures are required, use Test Method G42.  
1.3 These test methods apply to methods of polarization including sacrificial anodes or impressed current applied to the steel by a rectifier.  
1.4 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.  
1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

SIGNIFICANCE AND USE
4.1 This is a revision of the method for measuring rosin acids content combines the three major ways of determining the rosin acids content of pine chemicals products into a single method.  
4.1.1 For materials containing less than 15 % rosin, the modified Glidden procedure has gained acceptance. For materials containing more than 15 % rosin the modified Wolfe Method is preferred. The modified Wolfe and modified Glidden procedures differ only in their details. They have been combined here into a single procedure. This procedure can be run using either a potentiometer or an internal indicator to determine the end point of the titration. Use of a potentiometer is preferred and is the referee method. Use of an internal indicator is the principal alternative method. They will be referred to as the Potentiometric Method and the Internal Indicator Method.
SCOPE
1.1 These test methods cover the determination of rosin acids in tall oil, tall oil fatty acid, tall oil rosin, and other pine chemicals products.  
1.2 These test methods may not be applicable to adducts or derivatives of rosin, fatty acid, or other pine chemicals products.  
1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.  
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

SIGNIFICANCE AND USE
5.1 Latex paints dry very quickly which often causes difficulty in final appearance of painted areas, especially paints formulated below 100g/L VOC where lower amounts of solvents are in the formulated latex paint. This method is a means of determining the time available before a test paint cannot be worked into a previously painted area.
SCOPE

SIGNIFICANCE AND USE
5.1 This test method provides a measure of the dimensional stability and integrity of the coated edge of various composite wood products under accelerated moisture stress. It is widely used as an indicator or predictor of the anticipated performance of composite wood products during exterior exposure. It may be used for developmental evaluation of coatings, substrates, or both. It may also be useful for quality control or monitoring of the production of coated or uncoated composite wood products.
SCOPE
1.1 This test method is intended to serve as a means for measurement of swelling and cracking of the coated or uncoated edge of a composite wood substrate that has been subjected to wetting by a test solution containing surface active agent.  
1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.

SIGNIFICANCE AND USE
3.1 When used in conjunction with Guide D333, this practice will provide a comprehensive evaluation of resistance to stains caused by chemical reagents and household chemicals.  
3.2 This practice applies only to coatings applied in sufficient quantity to form a continuous film. It is recommended that the dry film thickness of the coating under test be reported.  
3.3 Results from stain tests conducted in accordance with this practice distinguish differences between coatings.
SCOPE
1.1 This practice covers evaluation of clear factory-applied coating systems on wood substrates.

1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

SIGNIFICANCE AND USE
3.1 Sward-type hardness rocker instruments have been used by the coatings industry for more than a half a century as a nondestructive test instrument to measure cure and ultimate surface hardness of organic coatings (see Refs. (1) through (2)).4 This test method is useful within laboratories to quickly screen and measure the surface hardness of candidate coatings.
Note 1: In previous task group work designed to establish an ASTM method for measuring hardness of organic coatings with Sward-type hardness rocker instruments, round-robin test results continually showed poor interlaboratory reproducibility. This lack of interlaboratory agreement could have resulted from dimensional variations among instruments, with the contact rocker rings as the most likely offender in that regard. There are several producers of Sward-type hardness rockers making instruments that differ among themselves in net weight and ring radius. Some of them exceed the measurements and net weight called for in this test method.
SCOPE
1.1 This test method covers the determination of the relative degree of surface hardness of organic coatings using a specific apparatus used in the coatings industry.  
1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.  
1.3 This test method does not purport to address all of the safety problems, if any, associated with its use.

1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

SIGNIFICANCE AND USE
5.1 Coatings attached to substrates are subjected to damaging impacts during the manufacture of articles and their use in service. In its use over many years, this test method for impact resistance has been found to be useful in predicting the performance of organic coatings for their ability to resist cracking caused by impacts.
SCOPE
1.1 This test method covers a procedure for rapidly deforming by impact a coating film and its substrate and for evaluating the effect of such deformation.  
1.2 This test method should be restricted to testing in only one laboratory when numerical values are used because of the poor reproducibility of the method. Interlaboratory agreement is improved when ranking is used in place of numerical values.  
1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

SCOPE
1.1 This standard consists of technical terms used in standards under the jurisdiction of ASTM Committee D01 (on Paint and Related Coatings, Materials, and Applications), and of definitions suitable for use in these standards.
Note 1: When any definition in this standards is quoted or published out of the context of this standard, editorially insert the following delimiting statement “for paints and related coatings, materials, and applications” after the dash following the term (in the absence of an existing delimiting statement). This will limit the filed of application of the term and definition to that approved by this committee.  
1.2 In this terminology standard, definitions used in other ASTM standards are indicated by following the definition with the designation of that standard. In some cases, a relevant D01 subcommittee is also listed. Definitions influenced by those used by other organizations are indicated by the acronym of the organization. Primary terms are given in bold, while narrower and unapproved terms are given in italics.  
1.3 There are several specialized terminology standards under the jurisdiction of Committee D01, as follows: D804, D1695, D6440, D6488, and D7188. Few definitions from those standards are included in Terminology D16. Therefore, in searches for definitions of paints and coatings terms, these standards should be included where appropriate.  
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

SIGNIFICANCE AND USE
5.1 After waterborne traffic paints are applied to a road, airstrip, or parking lot pavement, it is important that the paint films be sufficiently hardened, coalesced, or cured so they will not be removed by rain. This practice can be used to determine the relative performance of binders and other components within traffic paint for their effect on the water-wash off resistance of the coating. Some key elements of the coating that may affect water-wash-off performance are the quality and type of latex binder, the dry time of the coating (often conducted by Test Method D711), pigment volume concentration (PVC), and the relative water sensitivity of additives (for example, pigment dispersants, and surfactants) in the coating.
SCOPE
1.1 A traffic paint film freshly applied to a roadway, air strip, or parking lot may be exposed to rain of varying intensities shortly after application. This practice was designed to determine the relative water wash-off resistance of an applied traffic paint film under controlled laboratory conditions using a water faucet to simulate a heavy rain. This laboratory practice can also be used to compare conventional and fast-dry waterborne traffic paints and the effects of binders and other components in traffic for their relative ability to withstand a heavy rain soon after application.  
1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.

It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

SIGNIFICANCE AND USE
4.1 The ability of a paint or coating to resist deterioration of its physical and optical properties caused by exposure to light, heat, and water can be very significant for many applications. This practice is intended to induce property changes associated with end-use conditions, including the effects of sunlight, moisture, and heat. The exposure used in this practice is not intended to simulate the deterioration caused by localized weather phenomena such as atmospheric pollution, biological attack, and saltwater exposure.  
4.2 Cautions—Variation in results may be expected when different operating conditions are used. Therefore, no reference to the use of this practice shall be made unless accompanied by a report prepared according to Section 10 that describes the specific operating conditions used. Refer to Practice G151 for detailed information on the caveats applicable to use of results obtained according to this practice.
Note 1: Additional information on sources of variability and on strategies for addressing variability in the design, execution, and data analysis of laboratory accelerated exposure tests is found in Guide G141.  
4.2.1 The spectral power distribution of light from an open-flame carbon-arc is significantly different from that produced in light and water exposure devices using other carbon-arc configurations or other light sources. The type and rate of degradation and the performance rankings produced by exposures to filtered open-flame carbon-arcs can be much different from those produced by exposures to other types of laboratory light sources.  
4.2.2 Interlaboratory comparisons are valid only when all laboratories use the same type of carbon-arc, filters, and exposure conditions.  
4.3 Reproducibility of test results between laboratories has been shown to be good when the stability of materials is evaluated in terms of performance ranking compared to other materials or to a control.4,5 Therefore, exposure of a similar material of known...
SCOPE
1.1 This practice covers the selection of test conditions for accelerated exposure testing of coatings and related products in filtered open-flame carbon-arc devices conducted according to Practices G151 and G152. This practice also covers the preparation of test specimens, the test conditions suited for coatings, and the evaluation of test results.  
1.2 This practice does not cover enclosed carbon-arc exposures of paints and related coatings, which is described in Practice D5031/D5031M. Another procedure for exposing these products is covered by Practice D3361/D3361M, in which the specimens are subjected to radiation from an unfiltered open-flame carbon arc that produces shorter wavelengths and higher levels of short wavelength radiation than filtered open-flame or enclosed carbon arcs.

SIGNIFICANCE AND USE
5.1 After waterborne traffic paints are applied to a road pavement, it is important that they be sufficiently coalesced or cured so they will not be removed by rain. This practice can be used to determine the relative water wash-off resistance of waterborne traffic paints when exposed to a water spray simulated rain.
SCOPE
1.1 A newly applied traffic paint film may be exposed to rain of varying intensities shortly after application. Practice D7377 describes a practice for evaluating the water wash-off resistance of traffic paints to a hard rain using a steady stream of water from a faucet at a rate of approximately 5.7 L per min. Practice D7538 is a similar practice that describes the use of an adjustable nozzle atomizing spray device to deliver a spray of water that simulates rain rates from approximately 0.05 L to 0.5 L per min. This test can be used to compare conventional and fast-dry traffic paints for their relative ability to withstand rain soon after application on roadway surfaces.

SCOPE
1.1 This practice covers the selection of test conditions for accelerated exposure testing of coatings and related products in enclosed carbon arc devices operated according to Practices G151 and G153. This practice also covers the preparation of test specimens, the test conditions suited for coatings, and the evaluation of test results.  
1.2 This practice does not cover filtered open-flame carbon-arc exposures of paints and related coatings, which is described in Practice D822. Another procedure for exposing these products is covered by Practice D3361/D3361M, in which the specimens are subjected to radiation from an unfiltered open-flame carbon arc that produces shorter wavelengths and higher levels of short wavelength radiation than filtered open flame or enclosed carbon arcs.

SIGNIFICANCE AND USE
4.1 The viscosity value obtained by this test method gives information about the flow properties of the material under high-shear conditions similar to those encountered during application: brushing (see Test Method D4958), spraying, electrostatic disk, or roll coating.  
4.2 This test method is suitable for all paints and varnishes whether they are Newtonian in behavior or not. However, due to the narrow gap between the stationary and rotary parts of high-shear viscometers, this test method is more reproducible for paints having finer pigment dispersions as determined by Test Method D1210.
SCOPE
1.1 This test method covers the determination of the viscosity of paints, varnishes, and related products at a rate of shear of 12 000 s−1.  
1.2 Paints and varnishes that dry very rapidly may not give reproducible results with this test method. Measurements made at elevated temperatures may also give poor precision due to loss of volatiles and to drying.  
1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.  
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use.

1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

SIGNIFICANCE AND USE
5.1 Method A—Low voltage holiday detection is used to locate holidays and pinholes in thin-film coatings (up to 0.508 mm (20 mils) using a sponge wetted with tap water (and a wetting agent for coatings thicker than 10 mils). The water carries the current from the electrode through the holiday to the conductive substrate. The detector is grounded to the coated substrate. When the detector senses this flow of current it alarms.  
5.2 Method B—High voltage holiday detection is used to locate holidays and pinholes in thick-film coatings (greater than 20 mils), but can be used on coatings as low as 10 mils thick. A test voltage is selected and set. A charged Electrode is placed in contact with the coating, and the Detector is grounded to the coated substrate. When Electrical Breakdown occurs, electric current flows between the Detector’s electrode and the conductive substrate and emits an audible alarm.  
5.3 This standard does not apply to holiday detection of tape wraps used to protect pipe or coatings containing conductive raw materials such as conductive pigments and extenders.  
5.4 The thickness of a coating applied to ductile iron pipe, fittings, or other iron castings may vary substantially due to the inherent roughness of the substrate. For these applications, consult the coating manufacturer for their recommended test voltage setting when using Method B. The coating manufacturer’s recommended test voltage setting may be subject to approval by the owner.
Note 1: Use of voltage settings lower than those listed in this standard may increase the likelihood of non-detection.
SCOPE
1.1 These test methods cover the apparatus and procedures for detecting pinholes and holidays in coatings used to protect pipelines.  
1.2 Method A is designed to detect pinholes and holidays in thin-film coatings from 0.025 mm to 0.254 mm (1 mils to 10 mils) in thickness using ordinary tap water and an applied voltage of less than 100 V d-c. It is effective on films up to 0.508 mm (20 mils) thickness if a wetting agent is used with the water.  
1.3 Method B is designed to detect pinholes and holidays in thick-film coatings >0.508 mm (20 mils) This method can be used on any thickness of pipeline coating and utilizes applied voltages between 3.4 and 35 kV d-c.  
1.4 The values stated in SI units to three significant decimals are to be regarded as the standard. The values given in parentheses are for information only.  
1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

SIGNIFICANCE AND USE
3.1 This practice is useful in the laboratory to simulate roll-coated films.
SCOPE
1.1 This practice covers a procedure for applying a coil coating film of uniform thickness on a flat metal panel using wire-wound drawdown bars.  
1.2 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.3 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

SIGNIFICANCE AND USE
5.1 Many coatings used in the coil coating and other industries achieve a degree of solvent resistance after they have experienced a bake condition characterized by exposure to elevated temperatures in an oven over time. Insufficient bake, or occasionally over bake, may affect the intended chemical bonds or physical curing of the film and result in reduced solvent resistance.  
5.2 The mechanical rubbing machine provides consistent stroke length, rate, pressure, and contact area that are not subject to variables such as human fatigue (see Practice D5402).  
5.3 Factors other than bake can influence degree of solvent resistance of a coated surface. Paint film chemistry and composition, surface preparation, oven dwell time, oven air velocity, ambient oven temperature, oven profiling, film thickness, etc., all are influential. The test solvent used in the rub machine has a significant effect on the number of double rubs measured. Common solvents used for these tests include Methyl Ethyl Ketone (MEK), Methyl Isobutyl Ketone (MIBK), and Isopropyl Alcohol to name a few. The specific solvent to be used and the umber of double rubs to be achieved should be agreed upon between manufacturer and user for any given coating system, thickness, and application.
SCOPE
1.1 This test method covers a mechanical rub method for assessing the solvent resistance of an organic coating that chemically and/or physically changes during the curing process. This technique can be used in the laboratory, in the field, or in the fabricating shop.  
1.2 This test method does not specify the solvent, number of double rubs, or expected test results.  
1.3 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined.  
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

SIGNIFICANCE AND USE
4.1 This test method offers a means of comparing the relative linear shrinkage and coefficient of thermal expansion.  
4.1.1 The material to be tested is placed in the mold in a fluid or plastic state. As the material makes a transition to a solid state, it adheres to and captures the end studs.  
4.1.2 The linear shrinkage measured is the change in length that occurs after the material is rigid enough and strong enough to move the studs.  
4.2 This test method can be used for research purposes to provide information on linear changes taking place in the test materials. Other dimensional changes may occur that do not manifest themselves as changes in length.
SCOPE
1.1 This test method covers the measurement of the linear shrinkage during setting and curing and the coefficient of thermal expansion of chemical-resistant mortars, grouts, monolithic surfacings, and polymer concretes.  
1.2 A bar of square cross-section is cast to a prescribed length in a mold that holds measuring studs that are captured in the ends of the finished casting.  
1.2.1 The change in length after curing is measured and used to calculate shrinkage.
Note 1: Shrinkage determinations should not be made on sulfur mortars, since this test method cannot truly reflect the overall linear shrinkage of a sulfur mortar.  
1.2.2 The change in length at a specific elevated temperature is measured and used to calculate the coefficient of thermal expansion.  
1.3 This test method is limited to materials with aggregate size of 0.25 in. (6 mm) or less.  
1.4 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.  
1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

SIGNIFICANCE AND USE
4.1 Surfactant staining is a common problem with exterior house paints, particularly when subjected to humid environments (such as morning dew) shortly after application.  
4.2 Interior paints used in humid areas such as kitchens and bathrooms may also experience surfactant staining.  
4.3 Leaching of water-soluble materials may be dependent on colorant dispersions that are mixed into tint base paints. Other paint components may also affect the leaching of water-soluble materials.
SCOPE
1.1 This practice covers the ability of a latex paint film to resist staining caused by the leaching of water-soluble materials when contacted with water shortly after application.  
1.2 Water staining is attributed to the leaching of surfactants or other water-soluble materials from a paint film.  
1.3 The values stated in SI units are to be regarded as standard.  
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

SIGNIFICANCE AND USE
4.1 The procedures provide a broad range of techniques and photographic references to evaluate chalking of exterior paints.
SCOPE
1.1 These test methods cover the evaluation of the degree of chalking on white or tinted exterior paint films. These test methods describe the procedures recommended for transferring the chalk to a fabric or fingertip, which is then compared to photographic reference standards, or in the case of adhesive tapes, compared to a reflectance table or photographic reference standards, to determine the degree of chalking.  
1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.  
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

SIGNIFICANCE AND USE
5.1 Earlier methods for characterizing turpentine and related terpene products were based on physical properties, such as those in Specification D13 and Test Methods D801 and D802, and packed column gas chromatography for the major constituents (for example, α-pinene, β-pinene) as in Test Method D3009. As terpene products became widely used as chemical raw material, the separation and quantitation of compounds present at lower concentrations in the product became more important. The capillary gas chromatographic technique described in these test methods is a rapid and convenient means to perform these analyses.
SCOPE
1.1 These test methods describe the determination of the amounts of α-pinene, β-pinene, dipentene, terpene alcohols, and other terpene compounds in turpentine and related terpene products using capillary gas chromatography. The two methods for determining the amount of the individual terpene compounds are the “internal standard” method, which yields absolute values, and the “area percent” method, which yields relative values.  
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.  
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of the standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
Note 1: Overall this test method gives excellent repeatability but only moderate reproducibility. This greater than normal differential is a consequence of the variety of gas chromatography (GC) columns and other variables used by participants. These variables, coupled with the complex composition of the test products, enabled some workers to separate peaks that others reported as one peak; thus, this test method gives excellent precision within a given laboratory on a given GC. When laboratory to laboratory comparison have to be made, however, it is essential that the GC operating conditions be defined closely.  
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

SIGNIFICANCE AND USE
4.1 Water-insoluble materials present in a solvent expected to be completely water miscible may interfere with many uses of the solvent. This test method provides a measure of the miscibility of water-soluble solvents with a polar medium-water. It also provides a qualitative indication of the presence or absence of water-immiscible contaminants.  
4.2 The results of this test method may be used in assessing compliance with a specification. Prior to agreeing to this test method as the basis of a specification requirement, it may be desirable that the interpretation of what constitutes cloudiness or turbidity be agreed upon between the supplier and the purchaser.
SCOPE
1.1 This test method covers the determination of the miscibility of water-soluble solvents with water. While written specifically for testing acetone, isopropyl alcohol (isopropanol), and methyl alcohol (methanol), the method is suitable for testing most water-soluble solvents.  
1.2 This test method serves to detect water-immiscible contaminants qualitatively; the level of detection of these impurities varies widely with both the type of solvent and the type of impurity.  
1.3 The level of detection of water-insoluble materials depends upon the solvent tested and the type of impurity or impurities present, that is paraffin, olefin, aromatic, high molecular weight alcohol, or ketone, etc. There is, therefore, no specific level of impurity detected by this procedure.

SIGNIFICANCE AND USE
5.1 Viscosity is a measure of the fluidity of a material. Viscosity data are useful in the determination of the ease of stirring, pumping, dip coating, or other flow-related properties of paints and related fluids.  
5.2 This type of cup is used to measure viscosity because it is easy to use, robust, and may be used in tanks, reservoirs, and reactors.  
5.3 There are other types of apparatus for measuring viscosity in the laboratory that provide better precision and bias, including the Ford viscosity cup (Test Method D1200), and the rotational viscometer (Test Methods D2196).  
5.4 Certain higher shear rate devices such as cone/plate viscometers (Test Method D4287) provide more information about sprayability, roll coatability, and other high-shear rate related properties of coatings.
SCOPE
1.1 This test method covers the determination of viscosity of paints, varnishes, lacquers, inks, and related liquid materials by dip-type viscosity cups. This test method is recommended for viscosity control work within one plant or laboratory and should be used to check compliance with specifications only when sufficient controls have been instituted to ensure adequate comparability of results.  
1.2 Viscosity cups are designed for testing of Newtonian and near-Newtonian liquids. If the test material is non-Newtonian, for example, shear-thinning or thixotropic, another method, such as Test Methods D2196, should be used. Under controlled conditions, comparisons of the viscosity of non-newtonian materials may be helpful, but viscosity determination methods using controlled shear rate or shear stress are preferred.

ABSTRACT
This guide covers three levels of physical product standards (preparation, maintenance, and distribution) for color or geometric appearance, or both, of coatings commonly used in the coatings industry. Described here is terminology to describe each level, and techniques for generating and caring for standards. Product standards are the only standards by which products should be accepted or rejected for color or appearance. A master standard is generated from the concept color submitted by the customer. Duplicate master standards, when needed, are generated from the master standard. Working standards are generated from a duplicate master standard. They are used in the laboratory or on the production line to accept or reject the color or appearance of coatings. After initial generation, product standards must be maintained to ensure they remain valid. This guide considers the characteristics of product standards, factors to be considered in their creation, and factors to be considered in their replacement.
SIGNIFICANCE AND USE
5.1 High quality physical product standards for color or appearance are the keystone of a successful color control program. Standards are often grouped into three major categories: product standards, intermediate production control standards, and instrument standards. This guide deals only with physical product standards. Some instrument-based color control programs use “numerical standards,” derived from instrumental measurements of a physical product standard.
SCOPE
1.1 This guide covers three levels of physical product standards for color or appearance, or both, commonly used in the coatings industry, provides terminology to describe each level, and describes techniques for generating and caring for standards.  
1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.  
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

ABSTRACT
This test method covers the procedures for determining the viscosity of transparent liquids by bubble time method. The transparent liquids should be free from crystalline or gel particles. Test apparatus include a constant-temperature bath, standard viscosity tubes, a series of standard viscosity tubes as reference standards, timing device, tube racks, and viscosity tube corks.
SCOPE
1.1 This test method covers the determination of the viscosity in bubble seconds by timing. The bubble seconds are approximately equal to stokes for most liquids.  
1.2 The test method is applicable to transparent liquids that are free from crystalline or gel particles.  
1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.  
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

SIGNIFICANCE AND USE
5.1 This test method measures the amount of formaldehyde that is evolved from a coating containing melamine-formaldehyde resin(s) during cure at elevated temperature. Cure formaldehyde results from a side-reaction during cross-linking of functionalized polymers with melamine-formaldehyde resins. Cure formaldehyde is evolved in the final bake or cure oven, when the coating temperature is high enough to initiate cross-linking. Formaldehyde can be released from a coating during application, solvent flash-off and cure. Free formaldehyde is primarily evolved during coating application and solvent flash-off. Test Method D1979 measures “free formaldehyde” in amino resins and Test Method D6191 measures formaldehyde evolved from coatings at ambient temperature. This method measures only the formaldehyde released during heat cure, which is primarily “cure formaldehyde.”  
5.2 This test method is not intended to duplicate the evolved formaldehyde from an industrial process, but serves as a reproducible comparative laboratory evaluation.  
5.3 This test method has not been evaluated with catalyzed coating systems that cure at or below 40 °C, such as those used by the wood-finishing industry, and would likely require special adaptation for this application.
SCOPE
1.1 This test method is for the determination of formaldehyde evolved from melamine-formaldehyde-based coatings during the cure step. The results may be used to determine the “cure formaldehyde” evolved from a sample under controlled laboratory conditions.  
1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.  
1.3 This test method is capable of measuring from 500 μg/g to 22 000 μg formaldehyde/g dry coating under the test conditions specified (3 000 ml/min total flow, 50 ml/min DNPH tube flow). The ratio of total flow to DNPH tube flow could be adjusted to extend the range of the method.  
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

SIGNIFICANCE AND USE
5.1 This test method allows the user to make a determination of the blueness or yellowness of the tint undertone of titanium dioxide pigments, versus a reference pigment agreed upon by the parties to the test. This is an important measure of tone, since it gives both a measure of effective particle size, and quick approximation of the blue/yellow undertone that can be expected when a coating containing the titanium dioxide is tinted.  
5.2 Such matters as the vehicle for preparing the dispersions and the mechanical method of preparing the dispersion are left to the user. However, variation in these practices will lead to increased variance in the results, so users ought to fix these parameters, in-so-far as is possible, within any one laboratory. This will lead to reduced uncertainty of the results within that laboratory, and it is seldom that interlaboratory comparisons of this test result is needed.  
5.3 Each user must decide whether the loss of accuracy in his measurements due to variation of these parameters is negligibly small for the purpose for which the data are obtained.
SCOPE
1.1 This test method is intended to be used to determine the tint undertone (blue or yellow) of titanium dioxide pigments. This relates to the effective particle size of the pigment  
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.  
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use.

SIGNIFICANCE AND USE
4.1 Tinting strength is one of the most important properties of a white pigment. This test method provides a means of testing this property for quality control.  
4.2 This test method is a referee method, and the vehicle for preparing the dispersion and the black for tinting are suggested, but others may be used provided both the purchaser and the seller agree to the changes.  
4.3 The results obtained with a muller do not necessarily agree with industrial situations where different dispersing conditions exist. However, dispersing with a muller is a fast, relatively inexpensive way of testing tinting strength for routine quality control.
SCOPE
1.1 This test method describes the procedure for determining the relative tinting strength of white pigments by reflectance measurements of black tints.
