Standard Test Method for Water Immersion and Drying for Evaluation of Flood Damage Resistance

SIGNIFICANCE AND USE
5.1 This test method establishes water immersion, drying, and cleaning procedures to be used when determining whether building materials noted in 1.1 are flood damage resistant for applications that comply with the National Flood Insurance Program (NFIP) [44 CFR § 60.3(a)(3)].  
5.2 This test method exposes the test specimen to water immersion and drying conditions to simulate the effects of wetting and subsequent drying that occurs with a flood event. The wetting and drying exposure is followed by surface cleaning. This test method provides a measure of how test specimens may respond to water immersion, subsequent drying, and cleaning that occur with flood events.  
5.3 This test method is useful for determining water absorption characteristics of different test specimens in terms of percent increase in test specimen weight, their drying characteristics in terms of elapsed time to dry to equilibrium weight, and changes in physical appearance following water immersion and surface cleaning.  
5.4 This test method is useful in comparing the water absorption characteristics of different test specimens, their drying characteristics, and changes in physical appearance following water immersion and surface cleaning. This test method is also useful in comparing test specimen physical dimensions before water immersion, immediately following removal from water immersion, after drying, and after cleaning.  
5.5 The ability to directly compare test results will vary by many factors including test specimen size and whether test specimens are individual building materials or composite assemblies of building materials.
SCOPE
1.1 This test method is intended to apply to building materials used in construction below the base flood elevation (BFE) including, but not limited to: individual building materials and composite assemblies of building materials that constitute permanent integral parts of a finished building including walls, floors, ceilings, stairways, built-in partitions, finishes, cladding, and other similarly incorporated architectural and structural items.  
1.2 Requirements for evaluation of other hazards associated with flood damage including, but not limited to: debris impact, flood velocity, wave action, water pressure differential, scour, erosion, biological and chemical contaminants in floodwater, and other factors that would be adverse to continued use of the structure for its intended purpose including long-term occupant health impacts are outside of the scope of the methods presented herein.  
1.3 The water immersion, drying, and cleaning procedures specified in this test method establishes standard conditions for laboratory evaluation of test specimen response to water immersion, subsequent drying, and cleaning. The results of these tests are one factor in assessing the characteristics of building materials with regard to water immersion, drying, and ability to be cleaned. Application of these test results to predict these characteristics for actual building construction requires the evaluation of test conditions as compared to conditions of end-use.  
1.4 The water immersion and drying procedures shall not be construed as representative of water makeup, duration of immersion, or conditions of drying during an actual flood event because actual flood conditions vary with such factors as makeup of water, depth and duration of immersion, and ambient temperature and humidity.  
1.5 The cleaning procedures specified in this test method are intended to simulate surface cleaning that normally occurs after flooding.  
1.6 The cleaning procedures specified in this test method shall not be construed as superseding standards or manufacturer’s recommended methods for cleaning and restoration after flooding.  
1.7 A commentary to this test method is provided in Appendix X1.  
1.8 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mat...

ASTM G162-23(Practice)
Standard Practice for Conducting and Evaluating Laboratory Corrosion Tests in Soils

SIGNIFICANCE AND USE
4.1 This practice provides a controlled corrosive environment that has been utilized to produce relative corrosion information.  
4.2 The primary application of the data from this practice is to evaluate the performance of metallic materials for use in soil environments.  
4.3 This practice may not duplicate all field conditions and variables such as stray currents, microbiologically influenced corrosion, non-homogeneous conditions, pollutants in the soil, and long cell corrosion. The reproducibility of results in the practice is highly dependent on the type of specimen tested and the evaluation criteria selected as well as the control of the operating variables. In any testing program, sufficient replicates should be included to establish the variability of the results.  
4.4 Structures and components may be made of several different metals; therefore, the practice may be used to evaluate galvanic corrosion effects in soils (see Guide G71).  
4.5 Structures and components may be coated with sacrificial or noble metal coatings, which may be scratched or otherwise rendered discontinuous (for example, no coating on the edges of metal strips cut from a wide sheet). This test is useful to evaluate the effect of defective metallic coatings.  
4.6 Structures and components may be coated or jacketed with organic materials (for example, paints and plastics), and these coatings and jackets may be rendered discontinuous. The test is useful to evaluate the effect of defective or incompletely covering coatings and jackets.
Note 1: The corrosivity of soils strongly depends on soluble salt content (related parameters are chemistry and soil resistivity, see Test Methods G57 and G187), acidity or alkalinity (measured by soil pH, see Test Method G51), Temperature, and oxygen content (loose, for example, sand, or compact, for example, clay, soils are extreme examples, see Test Method G200 – oxidation-reduction potential). The manufacturer, supplier, or user, or combination the...
SCOPE
1.1 This practice covers procedures for conducting laboratory corrosion tests in soils to evaluate the potential for corrosion attack on engineering materials in soils. The test is conducted under laboratory ambient temperature unless the effect of temperature is being evaluated. This practice does not include provisions for microbiological influenced corrosion (MIC) testing, nor its influence on results.  
1.2 This practice covers specimen selection and preparation, test environments, evaluation, and reporting of test results.  
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.

ASTM E84-23c(Test Method)
Standard Test Method for Surface Burning Characteristics of Building Materials

SIGNIFICANCE AND USE
4.1 This test method is intended to provide only comparative measurements of surface flame spread and smoke density measurements with that of select grade red oak and fiber-cement board surfaces under the specific fire exposure conditions described herein.  
4.2 This test method exposes a nominal 24-ft (7.32 m) long by 20-in. (508 mm) wide specimen to a controlled air flow and flaming fire exposure adjusted to spread the flame along the entire length of the select grade red oak specimen in 51/2 min.  
4.3 This test method does not provide for the following:  
4.3.1 Measurement of heat transmission through the tested surface.  
4.3.2 The effect of aggravated flame spread behavior of an assembly resulting from the proximity of combustible walls and ceilings.  
4.3.3 Classifying or defining a material as noncombustible, by means of a flame spread index by itself.
SCOPE
1.1 This fire-test-response standard for the comparative surface burning behavior of building materials is applicable to exposed surfaces such as walls and ceilings. The test is conducted with the specimen in the ceiling position with the surface to be evaluated exposed face down to the ignition source. The material, product, or assembly shall be capable of being mounted in the test position during the test. Thus, the specimen shall either be self-supporting by its own structural quality, held in place by added supports along the test surface, or secured from the back side.  
1.2 Test Method E84 is a 10-min fire-test response method. The following standards address testing of materials in accordance with test methods that are applications or variations of the test method or apparatus used for Test Method E84:  
1.2.1 Materials required by the user to meet an extended 30-min duration tunnel test shall be tested in accordance with Test Method E2768.  
1.2.2 Wires and cables for use in air-handling spaces shall be tested in accordance with NFPA 262.  
1.2.3 Pneumatic tubing for control systems shall be tested in accordance with UL 1820.  
1.2.4 Combustible sprinkler piping shall be tested in accordance with UL 1887.  
1.2.5 Optical fiber and communications raceways for use in air handling spaces shall be tested in accordance with UL 2024.  
1.3 The purpose of this test method is to determine the relative burning behavior of the material by observing the flame spread along the specimen. Flame spread and smoke developed index are reported. However, there is not necessarily a relationship between these two measurements.  
1.4 The use of supporting materials on the underside of the test specimen has the ability to lower the flame spread index from those which might be obtained if the specimen could be tested without such support. These test results do not necessarily relate to indices obtained by testing materials without such support.  
1.5 Testing of materials that melt, drip, or delaminate to such a degree that the continuity of the flame front is destroyed, results in low flame spread indices that do not relate directly to indices obtained by testing materials that remain in place.  
1.6 Units—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.  
1.7 The text of this standard references notes and footnotes that provide explanatory information. These notes and footnotes, excluding those in tables and figures, shall not be considered as requirements of the standard.  
1.8 This standard is used to measure and describe the response of materials, products, or assemblies to heat and flame under controlled conditions, but does not by itself incorporate all factors required for fire-hazard or fire-risk assessment of the materials, products, or assemblies under actual fire conditions.  
1.9 This standard does not purport to address all of the safety concerns, if a...

ASTM E1623-22a(Test Method)
Standard Test Method for Determination of Fire and Thermal Parameters of Materials, Products, and Systems Using an Intermediate Scale Calorimeter (ICAL)

SIGNIFICANCE AND USE
5.1 This test method is used primarily to determine the heat release rate of materials, products, and assemblies. Other parameters are the effective heat of combustion, mass loss rate, the time to ignition, smoke and gas production, emissivity, and surface temperature. Examples of test specimens are assemblies of materials or products that are tested in their end-use thickness. Therefore, the test method is suitable for assessing the heat release rate of a wall assembly.  
5.2 Representative joints and other characteristics of an assembly shall be included in a specimen when these details are part of normal design.  
5.3 This test method is applicable to end-use products not having an ideally planar external surface. The heat flux shall be adjusted to be that which is desired at the average distance of the surface from the radiant panel.  
5.4 In this procedure, the specimens are subjected to one or more specific sets of laboratory test conditions. If different test conditions are substituted or the end-use conditions are changed, it is not always possible by or from this test to predict changes in the fire-test-response characteristics measured. Therefore, the results are valid only for the fire test exposure conditions described in this procedure.  
5.5 Test Limitations:  
5.5.1 The test results have limited validity if: (a) the specimen melts sufficiently to overflow the drip tray, or (b) explosive spalling occurs.  
5.5.2 Exercise caution in interpreting results of specimens that sag, deform, or delaminate during a test. Report observations of such behavior.
SCOPE
1.1 This fire-test-response standard assesses the response of materials, products, and assemblies to controlled levels of radiant heat exposure with or without an external ignitor.  
1.2 The fire-test-response characteristics determined by this test method include the ignitability, heat release rates, mass loss rates, visible smoke development, and gas release of materials, products, and assemblies under well ventilated conditions.  
1.3 This test method is also suitable for determining many of the parameters or values needed as input for computer fire models. Examples of these values include effective heat of combustion, surface temperature, ignition temperature, and emissivity.  
1.4 This test method is also intended to provide information about other fire parameters such as thermal conductivity, specific heat, radiative and convective heat transfer coefficients, flame radiation factor, air entrainment rates, flame temperatures, minimum surface temperatures for upward and downward flame spread, heat of gasification, nondimensional heat of gasification (1)2 and the Φ flame spread parameter (see Test Method E1321). While some studies have indicated that this test method is suitable for determining these fire parameters, insufficient testing and research have been done to justify inclusion of the corresponding testing and calculating procedures.  
1.5 The heat release rate is determined by the principle of oxygen consumption calorimetry, via measurement of the oxygen consumption as determined by the oxygen concentration and flow rate in the exhaust product stream (exhaust duct). The procedure is specified in 11.1. Smoke development is quantified by measuring the obscuration of light by the combustion product stream (exhaust duct).  
1.6 Specimens are exposed to a constant heat flux in the range of 0 to 50 kW/m2  in a vertical orientation. Hot wires are used to ignite the combustible vapors from the specimen during the ignition and heat release tests. The assessment of the parameters associated with flame spread requires the use of line burners instead of hot wire ignitors.  
1.6.1 Heat release measurements at low heat flux levels (2) require special considerations as described in Section A1.1.6.  
1.7 This test method has been developed for evaluations, design, or research and development of materials, products, or...

5.2 While actual building fire exposure conditions are not duplicated, this test method will assist in indicating those materials which do not act to aid combustion or add appreciable heat to an ambient fire.  
5.3 Materials passing the test are permitted limited flaming and other indications of combustion.
SCOPE
1.1 This fire-test-response test method covers the determination under specified laboratory conditions of the combustibility of building materials. Materials passing this test are typically classified as noncombustible materials.  
1.2 Limitations of this fire-test response test method are shown below.  
1.2.1 This test method does not apply to laminated or coated materials.  
1.2.2 This test method is not suitable or satisfactory for materials that soften, flow, melt, intumesce or otherwise separate from the measuring thermocouple.  
1.2.3 This test method does not provide a measure of an intrinsic property.  
1.2.4 This test method does not provide a quantitative measure of heat generation or combustibility; it simply serves as a test method with selected (end point) measures of combustibility.  
1.2.5 The test method does not measure the self-heating tendencies of materials.  
1.2.6 In this test method materials are not being tested in the nature and form used in building applications. The test specimen consists of a small, specified volume that is either (1) cut from a thick sheet; (2) assembled from multiple thicknesses of thin sheets; or (3) placed in a container if composed of granular powder or loose-fiber materials.  
1.2.7 Results from this test method apply to the specific test apparatus and test conditions and are likely to vary when changes are made to one or more of the following: (1) the size, shape, and arrangement of the specimen; (2) the distribution of organic content; (3) the exposure temperature; (4) the air supply; (5) the location of thermocouples.  
1.3 This test method includes two options, both of which use a furnace to expose test specimens of building materials to a temperature of 750 °C (1382 °F).  
1.3.1 The furnace for the apparatus for Option A consists of a ceramic tube containing an electric heating coil, and two concentric vertical refractory tubes.  
1.3.2 The furnace for the apparatus for Option B (Test Method E2652) consists of an enclosed refractory tube surrounded by a heating coil with a cone-shaped airflow stabilizer.  
1.4 This test method references notes and footnotes that provide explanatory information. These notes and footnotes, excluding those in tables and figures, shall not be considered as requirements of this test method.  
1.5 The values stated in SI units are to be regarded as standard. The values given in parentheses are for information only.  
1.6 This standard is used to measure and describe the response of materials, products, or assemblies to heat and flame under controlled conditions, but does not by itself incorporate all factors required for fire-hazard or fire-risk assessment of the materials, products, or assemblies under actual fire conditions.  
1.7 Fire testing is inherently hazardous. Adequate safeguards for personnel and property shall be employed in conducting these tests.  
1.8 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.  
1.9 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 Barri...

Standard Test Methods for Fire Tests of Building Construction and Materials

SIGNIFICANCE AND USE
4.1 These test methods are intended to evaluate the duration for which the types of building elements noted in 1.1 contain a fire, retain their structural integrity, or exhibit both properties during a predetermined test exposure.  
4.2 The test exposes a test specimen to a standard fire controlled to achieve specified temperatures throughout a specified time period. When required, the fire exposure is followed by the application of a specified standard fire hose stream applied in accordance with Practice E2226. The test provides a relative measure of the fire-test-response of comparable building elements under these fire exposure conditions. The exposure is not representative of all fire conditions because conditions vary with changes in the amount, nature and distribution of fire loading, ventilation, compartment size and configuration, and heat sink characteristics of the compartment. Variation from the test conditions or test specimen construction, such as size, materials, method of assembly, also affects the fire-test-response. For these reasons, evaluation of the variation is required for application to construction in the field.  
4.3 The test standard provides for the following:  
4.3.1 For walls, partitions, and floor or roof test specimens:
4.3.1.1 Measurement of the transmission of heat.
4.3.1.2 Measurement of the transmission of hot gases through the test specimen.
4.3.1.3 For loadbearing elements, measurement of the load carrying ability of the test specimen during the test exposure.  
4.3.2 For individual loadbearing members such as beams and columns:
4.3.2.1 Measurement of the load carrying ability under the test exposure with consideration for the end support conditions (that is, restrained or not restrained).  
4.4 The test standard does not provide the following:  
4.4.1 Information as to performance of test specimens constructed with components or lengths other than those tested.  
4.4.2 Evaluation of the degree by which the test sp...
SCOPE
1.1 The test methods described in this fire-test-response standard are applicable to assemblies of masonry units and to composite assemblies of structural materials for buildings, including loadbearing and other walls and partitions, columns, girders, beams, slabs, and composite slab and beam assemblies for floors and roofs. They are also applicable to other assemblies and structural units that constitute permanent integral parts of a finished building.  
1.2 It is the intent that classifications shall register comparative performance to specific fire-test conditions during the period of exposure and shall not be construed as having determined suitability under other conditions or for use after fire exposure.  
1.3 This standard is used to measure and describe the response of materials, products, or assemblies to heat and flame under controlled conditions, but does not by itself incorporate all factors required for fire hazard or fire risk assessment of the materials, products or assemblies under actual fire conditions.  
1.4 These test methods prescribe a standard fire exposure for comparing the test results of building construction assemblies. The results of these tests are one factor in assessing predicted fire performance of building construction and assemblies. Application of these test results to predict the performance of actual building construction requires the evaluation of test conditions.  
1.5 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.  
1.6 Fire testing is inherently hazardous. Adequate safeguards for personnel and property shall be employed in conducting these tests.  
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 e...
