1.1 本指南列出了试验方法，旨在确定用于低等级墙壁的加固或层压防水膜的可接受性能属性的最低水平。 1.2 本指南不包括胶结、整体或膨润土防水系统。 1.3 本指南不包括在地面上的板下或地面下的悬挂板上应用的膜，也不包括应用于挡土系统、挡水结构或隧道的膜。 1.4 由于土壤、设计、材料和安装中化学物质的变化，无法在防水膜的实验室测试与安装后的性能属性之间建立精确的相关性。 1.5 以英寸磅或国际单位制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。 1.6 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。 1.7 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。 ====意义和用途====== 4.1 防水膜应在连续或间歇潮湿的环境中，在建筑物的使用寿命内保持其防水完整性，并可能受到连续或间歇的静水压力。 它应该能抵抗可能损害膜和根系生长的化学物质。本指南列出了用于低等级墙壁的防水膜所需的最低性能属性。以前未用作防水膜材料的产品需要进行超出本指南范围的额外测试。本指南不适用于在役防水材料。防水膜和其他部件应符合ASTM产品标准（如有）。 4.2 局限性 在使用和使用之前，防水材料可能会暴露在各种条件下，因此任何一项测试都无法提供与所有暴露性能相关的评估。在特定暴露的所有评估中，也不需要进行所有测试。

1.1 This guide lists test methods intended to establish a minimum level of acceptable performance attributes for reinforced or laminated waterproofing membranes applied to below-grade walls. 1.2 This guide does not include cementitious, integral, or bentonite waterproofing systems. 1.3 This guide does not include membranes applied under slabs on grade or on suspended slabs below grade or applied to soil retaining systems, water containment structures, or tunnels. 1.4 It is not possible to establish a precise correlation between laboratory tests on waterproofing membranes and performance attributes after installation due to variations in chemicals in the soil, design, material, and installation. 1.5 The values stated in either inch-pound or SI 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 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. ====== Significance And Use ====== 4.1 A waterproofing membrane should maintain its watertight integrity for the life of the building in a continuously or intermittently moist environment and may be subject to continuous or intermittent hydrostatic pressure. It should resist chemicals that can harm the membrane and root growth. This guide lists minimum performance attributes required of waterproofing membranes applied to below-grade walls. Products not previously used as waterproofing membrane materials require additional tests beyond the scope of this guide. This guide is not intended for use on in-service waterproofing materials. Waterproofing membranes and other components should conform to ASTM product standards, if available. 4.2 Limitations— Prior to use and in service, waterproofing may be exposed to a variety of conditions so no one test will provide evaluations related to performance for all exposures. Neither will all tests be necessary in all evaluations for specific exposures.
