1.1 本规范涵盖了柔性氯化聚乙烯（CPE）薄膜，该薄膜在无胶泥、垫层或涂层的情况下使用，用于在可能因泄漏而造成昂贵的二次损坏的应用中，以及在需要非常长期可靠性能的情况下，建造隐蔽的水密封膜。例如喷泉、水池、花盆、淋浴和安全盘、瓷砖浴盆以及类似设施，一旦施工完成，膜就无法进入这些设施。包括对成分、强度和韧性、试验方法、工艺标准和标记方法的要求。 1.2 制造商可以选择在该产品中使用回收材料。回收材料必须符合第节的要求 4. . 1.3 用于表征板材特性的试验方法旨在确保质量和性能，但不一定足以达到设计目的。选择的试验方法主要是使用模拟实际安装和使用过程中膜所处环境的液体。 1.4 本规范不包括暴露在紫外线或阳光直射下的水密封膜。 1.5 以英寸-磅为单位的数值应视为标准值。括号中给出的值是到国际单位制的数学转换，仅供参考，不被视为标准值。 注1: 没有已知的ISO等效于本标准。 1.6 以下安全隐患警告仅适用于试验方法部分第节 14 ，本规范: 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。 1.7 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 flexible chlorinated polyethylene (CPE) 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 leakage, and where very long-term reliable performance is essential. Examples are fountains, pools, planters, shower and safe pans, tile tubs, and similar installations where the membrane is inaccessible once construction is complete. Included are requirements for composition, strength and toughness, test methods, workmanship criteria, and methods of marking. 1.2 Manufacturers have the option to use recycled materials in this product. Recycled materials must be in accordance with the requirements in Section 4 . 1.3 The test methods used to characterize the sheeting are intended to ensure quality and performance and are not necessarily adequate for design purposes. Test methods have been selected to be conducted primarily with liquids that simulate the environments to which the membrane will be subjected during actual installation and use. 1.4 This specification does not cover water-containment membranes exposed in use to ultraviolet light or direct sunlight. 1.5 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. Note 1: There is no known ISO equivalent to this standard. 1.6 The following safety hazards caveat pertains only to the test method portion, Section 14 , 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. 1.7 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.
