1.1 这些测试方法包括屋顶和防水用含沥青材料的采样、检查、物理测试和分析程序。这些材料包括但不限于卷材、盖板和瓦。允许对这些材料中的任何一种进行部分或完全涂层、表面处理或层压，或其组合。 1.2 本标准中的试验方法和程序按以下顺序出现: 部分 所容纳之物 6. 屋面类型 7. 取样 8. 质量和面积测定 9 代表性样本的选择 10 潮湿 11 柔韧性 12 质量损失和加热行为 13 撕裂强度 14 紧固件穿过阻力 15 小试样的制备和选择 用于分析 16 玻璃毡制品分析 17 有机毡屋面产品分析 18 不饱和毡灰 19 计算 20 调整后涂层细矿物和 背面堆焊 21 汇报 22 精度和偏差 1.3 以国际单位制或英寸-磅单位表示的数值应单独视为标准值。每个系统中规定的值可能不是精确的等效值；因此，每个系统应相互独立使用。将两个系统的值合并可能会导致不符合标准。 1.4 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 1.5 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。 ====意义和用途====== 4.1 这些测试方法包括屋顶和防水用沥青卷材、盖板和瓦的采样、检查、物理测试和分析程序。这些材料的其他成分包括但不限于:毡、垫子、薄膜、箔、矿物稳定剂、纸张和矿物表面。 4.2 这些测试方法包括参考测试方法的每个产品标准都不要求的测试 D228/D228M . 个别产品标准是要求进行符合性测试的权威。除产品标准中要求的测试外，不禁止进行其他测试，但这些测试方法并不声称其适用性或重要性。 4.3 从等于或小于1000包的批次中至少需要五个随机样本。参见第节 7. 有关采样详细信息。 4.4 每个样品都需要目视检查、物理测试和成分分析的结果。 分析数据进一步用于计算每个部件平均质量的可能最小值和可能范围。

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 Roofing 7 Sampling 8 Mass and Area Determination 9 Selection of Representative Specimens 10 Moisture 11 Pliability 12 Mass Loss and Behavior on Heating 13 Tear Strength 14 Fastener Pull-Through Resistance 15 Preparation and Selection of Small Test Specimens for Analyses 16 Analysis of Glass Felt Products 17 Analysis of Roofing Products with Organic Felts 18 Ash of Desaturated Felt 19 Calculation 20 Adjusting Back Coating Fine Mineral Matter and Back Surfacing 21 Report 22 Precision and Bias 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 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. ====== Significance And Use ====== 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.
