Standard Specification for Poly(Methyl Methacrylate) Acrylic Plastic Sheet

Standard Specification for Poly(Methyl Methacrylate) Acrylic Plastic Sheet

ABSTRACT
This specification covers monolithic methacrylate sheets produced by various processes. For this specification, methacrylate sheet shall be composed of polymerized acrylic monomers of which at least 80% shall be methyl methacrylate. Materials shall be classified under categories and finishes: Category A-1; Category A-2; Category B-1; and Category B-2.Finish 1; Finish 2; Finish 3; Type UVF; and Type UVT. Tests shall be performed to determine the properties of the material in accordance with following test methods: test conditions; index of refraction; specific gravity; luminous transmittance; haze; water-absorption; shrinkage; thermal stability; deflection temperature under flexural load; tensile strength and elongation at break; impact strength; spectral transmittance of Type UVF and UVT sheet; abrasion resistance; coating adhesion; and chemical resistance.
SCOPE
1.1 This specification covers monolithic methacrylate sheets produced by various processes. For this specification, methacrylate sheet shall be composed of polymerized acrylic monomers of which at least 80 % shall be methyl methacrylate.
Note 1—This specification is intended to consolidate the requirements of the Cast Methacrylate Plastic Sheets portion of discontinued Fed. Spec. L-P-391D, discontinued Specification D 702, Cast Methacrylate Plastic Sheets, Rods, Tubes and Shapes, and discontinued Specification D 1547, Extruded Acrylic Plastic Sheet.
1.2 This specification is intended to cover acrylic sheet for general-purpose applications. For specialty applications consult the appropriate use standards.
1.3 The following safety hazards caveat pertains only to the test methods portion, Section 8, of this specification: 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 and health practices and determine the applicability of regulatory limitations prior to use.
1.4 Acrylic sheet is used frequently in applications in which extreme clarity, lack of optical distortion and absence of any foreign particulate matter are of primary significance. Reground material may be used as long as careful control is used to eliminate adverse effects on these properties. The use of recycled material in type B-1 and B-2 sheet, may have adverse effects on these properties which would preclude its use in most cases. The use of recycled or reground material is not possible for type A-1 and A-2 materials since the sheet is produced directly from monomer
Note 2—This standard is similar to ISO 7823-1:1987 (E) in title only. The technical content is significantly different.

Standard Specification for Polyethylene Sheeting for Construction, Industrial, and Agricultural Applications

ABSTRACT
This specification covers polyethylene sheeting with a determined thickness intended for construction, industrial and agricultural applications. The sheeting shall be made from polyethylene or modified polyethylene, such as an ethylene copolymer consisting of a major portion of ethylene in combination with a minor portion of some other monomer, or a mixture of polyethylene with a lesser amount of other polymers. General requirements for the material are also observed according to their appearance, dimensions in size and tolerance and minimum net weight. The sheeting may be natural, color-tinted, translucent or opaque. The tests given are intended primarily for use as production tests in conjunction with manufacturing processes and inspection methods to insure conformity of sheeting with the requirements of this specification. These tests shall be done in order to determine the following properties: thickness, length and width, weight, impact resistance, tensile properties, reflectance, luminous transmittance, water vapor transmission, and heat sealability.
SCOPE
1.1 This specification covers polyethylene sheeting, 250 μm (0.010 in. or 10 mils) or less in thickness, intended for construction, industrial, and agricultural applications.  
1.2 The values stated in SI units are to be regarded as the standard.  
1.3 The following precautionary statement pertains only to the test methods portion, Section 8 of this specification: 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 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 and health practices and determine the applicability of regulatory limitations prior to use.

ASTM D4272/D4272M-23(Test Method)
Standard Test Method for Total Energy Impact of Plastic Films by Dart Drop

SIGNIFICANCE AND USE
5.1 Evaluation of the impact toughness of film is important in predicting the performance of a material in applications such as packaging, construction, and other uses. The test simulates the action encountered in applications where moderate-velocity blunt impacts occur in relatively small areas of film.  
5.2 The values obtained by this test method are highly dependent on the method and conditions of film fabrication as well as the type and grade of resin.  
5.3 Test methods employing different missile velocities, impinging surface diameters, or effective specimen diameters will most likely produce different results. Data obtained by this test method cannot necessarily be compared directly with those obtained by other test methods.  
5.4 The impact resistance of a film, while partly dependent on thickness, does not have a simple correlation with sample thickness. Hence, impact values expressed in joules [ft·lbf] normalized over a range of thickness will not necessarily be linear with thickness. Data from this test method are comparable only for specimens that vary by no more than ±15 % from the nominal or average thickness of the specimens tested.  
5.5 The test results obtained by this test method are greatly influenced by the quality of film under test. The influence of variability of data obtained by this procedure will, therefore, depend strongly on the sample quality, uniformity of film thickness, the presence of die marks, contaminants, etc.  
5.6 Several impact test methods are used for film. It is sometimes desirable to know the relationships among test results derived by different test methods. A study was conducted in which four films made from two resins (polypropylene and linear low-density polyethylene), with two film thicknesses for each resin, were impacted using Test Methods D1709 (Test Method A), Test Method D3420 (Procedures A and B), and Test Method D4272. The test results are shown in Appendix X2. Differences in results between Test Methods...
SCOPE
1.1 This test method describes the determination of the total energy impact of plastic films by measuring the kinetic energy lost by a free-falling dart that passes through the film.  
1.2 Units—The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the 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.
Note 1: Film has been arbitrarily defined as sheeting having nominal thickness not greater than 0.25 mm [0.010 in.].
Note 2: This test method and ISO 7765–2 address the same subject matter, but differ in technical content (and results cannot be directly compared between the two test methods). The ISO test method calls for a direct readout of energy by using a load cell as part of the impactor head, while Test Method D4272 calls for a constant weight impactor, then measuring the time of travel through a given distance to get energy values.

Standard Test Method for Transparency of Plastic Sheeting

SIGNIFICANCE AND USE
4.1 The attribute of clarity of a sheet, measured by its ability to transmit image-forming light, correlates with its regular transmittance. Sensitivity to differences improves with decreasing incident beam- and receptor-angle. If the angular width of the incident beam and of the receptor aperture (as seen from the specimen position) are of the order of 0.1° or less, sheeting of commercial interest have a range of transparency of about 10 to 90 % as measured by this test. Results obtained by the use of this test method are greatly influenced by the design parameters of the instruments; for example, the resolution is largely determined by the angular width of the receptor aperture. Caution should therefore be exercised in comparing results obtained from different instruments, especially for samples with low regular transmittance.  
4.2 Regular transmittance data in accordance with this test method correlate with the property commonly known as “see-through,” which is rated subjectively by the effect of a hand-held specimen on an observer's ability to distinguish clearly a relatively distant target. This correlation is poor for highly diffusing materials because of interference of scattered light in the visual test.
SCOPE
1.1 This test method covers the measurement of the transparency of plastic sheeting in terms of regular transmittance (Tr). Although generally applicable to any translucent or transparent material, it is principally intended for use with nominally clear and colorless thin sheeting.  
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.
Note 1: There is no known ISO equivalent to this standard.

Standard Test Method for Propagation Tear Resistance of Plastic Film and Thin Sheeting by Pendulum Method

SIGNIFICANCE AND USE
4.1 This test method is of value in ranking relative tearing resistance of various plastic films and thin sheeting of comparable thickness. Experience has shown the test to have its best reliability on relatively less extensible films and sheeting. Variable elongation and oblique tearing effects on the more extensible films preclude its use as a precise production-control tool for these types of plastics. This test method should be used for specification acceptance testing only after it has been demonstrated that the data for the particular material are acceptably reproducible. This test method should be used for service evaluation only after its usefulness for the particular application has been demonstrated with a number of different films.  
4.2 This test method has been widely used as one index of the tearing resistance of plastic film and thin sheeting used in packaging applications. While it is not always be possible to correlate film tearing data with its other mechanical or toughness properties, the apparatus of this test method provides a controlled means for tearing specimens at straining rates approximating some of those found in actual packaging service.  
4.3 Due to orientation during their manufacture, plastic films and sheeting frequently show marked anisotropy in their resistance to tearing. This is further complicated by the fact that some films elongate greatly during tearing, even at the relatively rapid rates of loading encountered in this test method. The degree of this elongation is dependent in turn on film orientation and the inherent mechanical properties of the polymer from which it is made. These factors make tear resistance of some films reproducible between sets of specimens to ±5 % of the mean value, while others potentially show no better reproducibility than ±50 %.  
4.4 Data obtained by this test method may supplement that from Test Method D1004, wherein the specimen is strained at a rate of 50 mm (2 in.) per minute. However, spec...
SCOPE
1.1 This test method2 covers the determination of the average force to propagate tearing through a specified length of plastic film or nonrigid sheeting after the tear has been started, using an Elmendorf-type tearing tester. Two specimens are cited, a rectangular type, and one with a constant radius testing length. The latter shall be the preferred or referee specimen.  
1.2 Because of (1) difficulties in selecting uniformly identical specimens, (2) the varying degree of orientation in some plastic films, and (3) the difficulty found in testing highly extensible or highly oriented materials, or both, the reproducibility of the test results may be variable and, in some cases, not good or misleading. Provisions are made in the test method to address oblique directional tearing which may be found with some materials.  
1.3 The values stated in SI units are to be regarded as 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. Specific precautionary statements are given in 13.1.
Note 1: Film has been arbitrarily defined as sheeting having nominal thickness not greater than 0.25 mm (0.010 in.).
Note 2: This standard is equivalent to ISO 6383-2.  
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.

Standard Test Method for Wetting Tension of Polyethylene and Polypropylene Films

SIGNIFICANCE AND USE
5.1 When a drop of liquid rests on the surface of a solid, and a gas is in contact with both, the forces acting at the interfaces must balance. These forces can be represented by surface energies acting in the direction of the surfaces and it follows that:
   where:
  θ  =  angle of contact of the edge of the drop with the solid surface,   γGL  =  surface energy of the gas - liquid interface,   γGS  =  surface energy of the gas - solid interface, and   γSL  =  surface energy of the solid - liquid interface.    
5.1.1 The right side of the above equation (the difference between the surface energies of the gas - solid and solid - liquid interfaces) is defined as the wetting tension of the solid surface. It is not a fundamental property of the surface but depends on interaction between the solid and a particular environment.  
5.1.2 When the gas is air saturated with vapors of the liquid, γGL will be the surface tension of the liquid. If the angle of contact is 0° the liquid is said to just wet the surface of the solid, and in this particular case (since cos θ = 1) the wetting tension of the solid will be equal to the surface tension of the liquid.  
5.2 The ability of polyethylene and polypropylene films to retain inks, coatings, adhesives, etc., is primarily dependent upon the character of their surfaces, and can be improved by one of several surface-treating techniques. These same treating techniques have been found to increase the wetting tension of a polyethylene or a polypropylene film surface in contact with mixtures of formamide and ethyl Cellosolve in the presence of air. It is therefore possible to relate the wetting tension of a polyethylene or a polypropylene film surface to its ability to accept and retain inks, coatings, adhesives, etc. The measured wetting tension of a specific film surface can only be related to acceptable ink, coating, or adhesive retention through experience. Wetting tension in itself is not a completely acceptable measur...
SCOPE
1.1 This test method covers the measurement of the wetting tension of a polyethylene or polypropylene film surface in contact with drops of specific test solutions in the presence of air.  
1.2 The values stated in SI units are to be regarded as standard. The values given in parentheses are mathematical conversions to inch-pound units that are provided for information only and are not considered standard.
Note 1: This test method and the specified reagents were specifically developed for polyethylene and polypropylene films. It is possible to utilize this test method and the specified reagents for films composed of other polymers, but this can affect the surface energies of the gas-liquid and solid-liquid interfaces, which will affect the contact angle and wetting tension. The applicability and significance for use of non-polyolefin materials must be established by the user.  
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. Specific hazards statements are given in Section 9.
Note 2: This test method is equivalent to ISO 8296.

The material may be transparent, translucent, or opaque, and may be plain, printed, embossed, or otherwise surface treated. This specification designates three general-purpose types of vinyl chloride film and sheeting - calendered, extruded, and cast. The materials shall be tested for its tensile strength and elongation at rapture, tear resistance, volatile loss, water extraction, low temperature impact, burning rate, shrinkage, and color fastness to rubbing.
SCOPE
1.1 This specification covers nonrigid, unsupported vinyl chloride plastic film and sheeting in which the resin portion of the composition contains at least 90 % vinyl chloride. The remaining 10 % can include one or more monomers copolymerized with vinyl chloride, or consist of other resins mechanically blended together with poly(vinyl chloride) or copolymers thereof.  
1.2 The vinyl chloride plastic film and sheeting covered herein shall be 0.075 to 0.25 mm (3 to 10 mils) in thickness for film and greater than 0.25 mm in thickness for sheeting. The film and sheeting shall include the stabilizers and plasticizers necessary to meet the requirements of this specification. This specification covers transparent, translucent, or opaque film and sheeting that is plain, printed, embossed, or otherwise surface treated.  
1.3 The values stated in SI units are to be regarded as the standard.  
1.4 The following safety hazards caveat pertains only to the test methods portion, Section 10, of this specification: 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.
Note 1: There is no known ISO equivalent to this standard.  
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.
