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.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 mathematical conversions to SI units that are provided for information only and are not considered 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.

This test method is intended for laboratory screening of materials. Due to large differences in the composition, pressure, and temperature of geothermal fluids, this test method may not correlate with actual service conditions. It does not consider the effects of geothermal fluid combined with oxidizing environments, stress loading, or thermal cycling.1.1 This test method covers a procedure for a laboratory test for performing an initial evaluation (screening) of nonmetallic seal materials by immersion in a simulated geothermal test fluid.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 this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. For specific precautionary statements, see Section 6 and 11.7.

4.1 This test method is useful for accurate measurement of from a wide variety of glass samples, whose ranges from 1.48–1.55. 4.2 It should be recognized that measurement of surface fragments, especially from float glass samples, can result in refractive index values which are different than the refractive index values of fragments from the interior of (for example, bulk) the same broken glass source (5). 4.3 The precision of this test method shall be established in each laboratory that employs it as part of the validation protocol (see Section 9). 4.4 It should be recognized that this technique measures the refractive index of the glass at the match point temperature, which will be higher than ambient temperature, and thus, may give different values from those obtained by other methods, which measure the refractive index at room temperature. 1.1 This test method covers a procedure for measuring and comparing the refractive index (η) at a fixed wavelength (λ) and temperature (T) ( ) of glass from known sources to recovered fragments from a questioned source. 1.2 This test method does not include the measurement of optical dispersion or the measurement of refractive index ( ) at any other wavelength other than the Sodium D line ( ). This method employs a narrow band pass filter at 589 nm, but other filters could be employed using the described method, allowing the to be determined at other wavelengths, and therefore, also allowing for the dispersion value to be calculated. 1.3 Alternative methods for the determination of are listed in Refs (1-5).2 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 cannot replace knowledge, skills, or abilities acquired through education, training, and experience and is to be used in conjunction with professional judgment by individuals with such discipline-specific knowledge, skills, and abilities. 1.6 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. 1.7 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.
