1.1 本规范涵盖了用聚酯织物作为主要增强材料增强的预制改性沥青片材，有或没有颗粒，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，旨在用于制造多层屋面和防水膜。 1.2 用含有玻璃丝的聚酯织物增强的改性沥青薄板也包括在本规范中（见 附注1 ). 附注1: 当使用玻璃纱线时，在改性沥青片的制造中改善聚酯垫的加工，并减少在生产过程中可能引入的变形。玻璃纱线通常在增强材料中所占的比例很小，对成品的物理性能的贡献不大，以致于使这些产品满足规范的要求 D6162/D6162M . 1.3 本规范仅作为材料规范。关于特定屋顶结构或应用技术的适用性的问题超出了此范围。 1.4 用于表征板材的规定测试和性能限值旨在建立最小性能。就地屋顶系统设计标准，如耐火性、场强、抗冲击/穿刺性、材料兼容性、抗隆起性等，超出了本材料规范的范围。 1.5 以SI单位或英寸-磅单位表示的值应单独视为标准值。每个系统中陈述的值可能不完全等同；因此，每个系统应独立使用。合并两个系统的值可能导致不符合标准。1.6 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》中确立的国际公认的标准化原则制定的。

1.1 This specification covers prefabricated modified bituminous sheet materials reinforced with polyester fabric as the primary reinforcement, with or without granules, which 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 Modified bituminous sheets reinforced with polyester fabric containing glass yarns are also covered by this specification (see Note 1 ). Note 1: When used, glass yarns improve processing of polyester mats in the manufacture of the modified bitumen sheets and reduce distortions that may be introduced during production. Glass yarns are typically a small percentage of the reinforcement and do not contribute to the physical properties of the finished product so much as to make these products meet the requirements of Specification D6162/D6162M . 1.3 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. 1.4 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. 1.5 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. 1.6 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.
