1.1 本试验方法包括评估屋面薄膜试样在不允许水通过的情况下所能承受的最大静态穿刺载荷。 1.2 该实验室测试在任何所需温度下使用工厂制造或实验室制备的片状薄膜样品进行。 1.3 试验方法适用的屋顶膜样品包括沥青积层、聚合物改性沥青、硫化橡胶、非硫化聚合物和热塑性材料。 1.3.1 本试验方法适用于这些薄膜样品，包括其在植物屋顶系统中的应用。 1.4 本试验方法不适用于骨料表面薄膜试样，但适用于具有工厂应用颗粒的试样。 1.5 以国际单位制或英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完全相等；因此，每个系统应独立使用。 将两个系统的值合并可能导致不符合标准。 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建立适当的安全、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》中确立的国际公认标准化原则制定的。 =====意义和用途====== 5.1 影响许多薄膜屋面系统性能的一个重要因素是它们抵抗静态刺穿载荷的能力。该测试方法提供了一种评估静态穿刺阻力的方法。 5.2 该测试方法可用于比较作为各种绝缘衬底函数的单一类型膜的抗穿刺性，或者相反，用于比较设置在单一类型绝缘上的多个膜样品的电阻。 5.3 温度对耐穿刺性的影响可以通过在受控条件下使用环境室、烘箱或冷冻机等设备进行试验来研究。 5.4 该测试方法可用于制定薄膜屋面系统的性能标准。 5.5 该测试方法可用于开发薄膜屋面系统的抗静电刺穿性分类。 5.6 虽然认为，如果已知使用荷载和温度条件，通过实验室试验获得的结果可以提供现场薄膜屋面系统静态抗穿刺性的测量，但尚未建立直接相关性。 5.7 该测试方法可用于评估植物屋顶系统中使用的膜的静态抗穿刺性。

1.1 This test method covers evaluation of the maximum static puncture load that roofing membrane specimens can withstand without allowing the passage of water. 1.2 This laboratory test is conducted at any desired temperature using sheet membrane specimens manufactured in a factory or prepared in a laboratory. 1.3 Roof membrane specimens to which the test method is applicable include bituminous built-up, polymer-modified bitumens, vulcanized rubbers, non-vulcanized polymeric, and thermoplastic materials. 1.3.1 The applicability of this test method to these membrane specimens includes their use in vegetative roof systems. 1.4 This test method is not applicable to aggregate-surfaced membrane specimens, but it is applicable to specimens having factory-applied granules. 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 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 ====== 5.1 An important factor affecting the performance of many membrane roofing systems is their ability to resist static puncture loads. This test method provides a means for assessing static puncture resistance. 5.2 This test method can be used to compare the puncture resistance of a single type of membrane as a function of a variety of insulation substrates or, conversely, to compare the resistance of a number of membrane specimens set on a single type of insulation. 5.3 The effect of temperature on puncture resistance can be studied by conducting the test under controlled conditions using such equipment as an environmental chamber, oven, or freezer. 5.4 This test method can be useful for developing performance criteria for membrane roofing systems. 5.5 This test method can be useful for developing classifications of the static puncture resistance of membrane roofing systems. 5.6 While it is considered that the results obtained by this laboratory test can afford a measure of the static puncture resistance of membrane roofing systems in the field provided that service loads and temperature conditions are known, no direct correlation has yet been established. 5.7 This test method can be useful for evaluating the static puncture resistance of membranes used in vegetative roof systems.
