1.1 本规范涵盖了无胶泥、垫层或涂层的聚氯乙烯（PVC）柔性薄膜，用于在可能因漏水造成昂贵二次损坏且长期可靠性能至关重要的应用中建造隐蔽式防水膜。例如，喷泉、水池、花盆、淋浴和安全盆、瓷砖浴缸或类似的湿设施，一旦施工完成，膜就无法使用。包括材料和板材的要求、试验方法、工艺标准和标记方法。 1.2 根据第5节的要求，可在本产品中使用回收材料。 1.3 测试旨在确保质量和性能，而非设计目的。已选择主要使用模拟实际使用期间膜所处环境的液体进行试验。 1.4 本规范不包括暴露于紫外线下的防水膜。 1.5 以英寸-磅单位表示的数值应视为标准值。括号中给出的值仅供参考。 1.6 没有已知的ISO等同于本标准。 1.7 以下预防性警告仅适用于试验方法部分，第节 11 本规范中的: 本标准并不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。 1.8 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 poly(vinyl chloride) (PVC) flexible sheeting which is used without mastic, bedding, or coating for construction of concealed water-containment-membranes in applications where there is potential for costly secondary damage from water leakage and very long-term reliable performance is essential. Examples are fountains, pools, planters, shower and safe pans, tile tubs, or similar wet installations where the membrane is inaccessible once the construction is complete. Included are requirements for materials and sheeting, test methods, workmanship criteria, and methods of marking. 1.2 Recycled materials may be used in this product in accordance with the requirements in Section 5. 1.3 The tests are intended to ensure quality and performance and are not intended for design purposes. Tests have been selected to be conducted primarily with liquids that simulate the environment to which the membrane will be subjected during actual use. 1.4 This specification does not cover water-containment membranes exposed to ultraviolet light. 1.5 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only. 1.6 There is no known ISO equivalent to this standard. 1.7 The following precautionary caveat pertains only to the test method portion, Section 11 , of 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. 1.8 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.
