1.1 本规范涵盖了带有玻璃纤维增强的预制改性沥青板材料，带或不带颗粒，使用苯乙烯-丁二烯-苯乙烯（SBS）热塑性弹性体作为主要改性剂，用于制造多层屋面和防水膜。 1.2 本规范仅作为材料规范。与特定屋顶结构或应用技术的适用性有关的问题不在此范围内。 1.3 用于表征板材特性的规定试验和性能极限旨在确定最低性能。现浇屋面系统设计标准，如耐火性、场强、抗冲击/刺穿性、材料兼容性、抗拔力等，均超出了本材料规范的范围。 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。 1.5 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。

1.1 This specification covers prefabricated modified bituminous sheet materials with glass fiber reinforcement, with or without granules, that use styrene butadiene styrene (SBS) thermoplastic elastomer as the primary modifier and are intended for use in the fabrication of multiple ply roofing and waterproofing membranes. 1.2 This specification is intended as a material specification only. Issues regarding the suitability of the specific roof constructions or application techniques are beyond this scope. 1.3 The specified tests and property limits used to characterize the sheet materials are intended to establish minimum properties. In-place roof system design criteria, such as fire resistance, field strength, impact/puncture resistance, material compatibility, uplift resistance, and others, are factors beyond the scope of this material specification. 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 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.
