【国外标准】 Standard Test Methods for Sampling, Testing, and Analysis of Asphalt Roll Roofing, Cap Sheets, and Shingles Used in Roofing and Waterproofing

4.1 These test methods include procedures for sampling, examination, physical testing, and analyses of asphalt roll roofing, cap sheets, and shingles used in roofing and waterproofing. Other components of these materials are allowed to include, but are not limited to: felts, mats, films, foils, mineral stabilizers, papers, and mineral surfacing.4.2 These test methods include tests that are not required by every product standard that references Test Methods D228/D228M. The individual product standards are the authority for which tests are required for compliance. It is not prohibited to run tests in addition to those required in the product standards, but these test methods make no claim to their suitability or significance.4.3 A minimum of five random samples are required from lots equal to or less than 1000 packages. See Section 7 for sampling details.4.4 The results of a visual examination, physical testing, and compositional analysis are required for each sample. The analytical data are further used to compute the probable minimum and the probable range for the average mass of each of the components.1.1 These test methods cover procedures for sampling, examination, physical testing, and analyses of asphalt-containing materials used in roofing and waterproofing. These materials include but are not limited to roll roofing, cap sheets, and shingles. Any of these materials is allowed to be partially or fully coated, surfaced, or laminated, or a combination thereof.1.2 The test methods and procedures in this standard appear in the following order:Section Content   6 Types of Roofing7 Sampling8 Mass and Area Determination9 Selection of Representative Specimens10 Moisture11 Pliability12 Mass Loss and Behavior on Heating13 Tear Strength14 Fastener Pull-Through Resistance15 Preparation and Selection of Small Test Specimensfor Analyses16 Analysis of Glass Felt Products17 Analysis of Roofing Products with Organic Felts18 Ash of Desaturated Felt19 Calculation20 Adjusting Back Coating Fine Mineral Matter andBack Surfacing21 Report22 Precision and Bias1.3 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the 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.
