1.1 本规范涵盖木瓦形式的沥青屋顶，由玻璃毡或毡组成，两面浸有沥青并涂有沥青，在风化面上涂有矿物颗粒。本规范旨在对生产的产品进行评估。测试方法、物理要求和最小质量应在包装后立即测量，或在买方和卖方约定的合理时间，在制造后和安装前测量。本文所述产品在使用后和在役使用期间的物理和性能要求超出了本材料规范的范围。 1.2 符合本规范要求的角撑板应具有不小于51 mm[2 in.]的顶盖。 1.3 木瓦应提供工厂应用的自密封粘合剂，或设计为在木瓦安装期间锁定在一起。 1.4 以国际单位制或英寸磅单位表示的数值应单独视为标准。每个系统中规定的值可能不是完全相等的；因此，每个系统应独立使用。将两个系统的值结合起来可能会导致不符合标准。 1.5 以下安全隐患警告仅适用于本规范中描述的测试方法: 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的使用者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。 1.6 本国际标准是根据世界贸易组织技术性贸易壁垒委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认的标准化原则制定的。

1.1 This specification covers asphalt roofing in shingle form, composed of glass felt or felts impregnated and coated on both sides with asphalt, and surfaced on the weather side with mineral granules. This specification is designed for the evaluation of products as manufactured. The test methods, physical requirements, and minimum masses are to be measured immediately after packaging or at a reasonable time, as agreed upon between buyer and seller, after manufacture and before installation. Physical and performance requirements after application and during in-service use of the products described herein are beyond the scope of this material specification. 1.2 Shingles meeting this specification are intended to be applied with a headlap of not less than 51 mm [2 in.]. 1.3 The shingles shall be supplied with a factory-applied self-sealing adhesive or be designed to be locked together during installation of the shingles. 1.4 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. 1.5 The following safety hazards caveat pertains only to the test method described in 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. 1.6 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.
