1.1 该定性测试方法确定沥青基屋顶或防水材料在规定条件下密封穿透材料的紧固件周围并防止液态水在穿透处通过材料传输的能力。 1.2 该测试方法被ASTM或其他基于共识的屋顶和防水产品规范采用，作为评估紧固件周围密封能力的标准化方法。不禁止将产品进行旨在模拟环境应力和应变的调节后，本试验方法的性能。 1.3 本试验方法的正文参考了提供解释材料的注释和脚注。这些注释和脚注（不包括表格和图表中的注释和脚注）不应被视为标准的要求。1.4 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。 1.5 本标准并不旨在解决与其使用相关的所有安全性问题（如果有）。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法规限制的适用性。 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。======意义和用途====== 5.1 在某些情况下，紧固件穿透沥青基屋面或防水材料是材料安装过程的必要部分，或者发生在其他系统部件的安装过程中。当紧固件作为施工过程中有目的和有计划的一部分穿透材料时，有理由预期设计用于限制液态水在穿透紧固件和材料之间的界面处迁移的材料会这样做。这种定性测试方法提供了一种评估材料在规定条件下测试时限制紧固件穿透处水迁移的能力的方法。

1.1 This qualitative test method determines the capability of asphalt-based roofing or waterproofing material to seal around a fastener that penetrates the material and prevent transmission of liquid water through the material at the penetration under defined conditions. 1.2 This test method is provided for adoption by ASTM or other consensus-based roofing and waterproofing product specifications as a standardized means to evaluate capability to seal around a fastener. Performance of this test method after subjecting the product to conditioning intended to simulate environmental stresses and strains is not prohibited. 1.3 The text of this test method references notes and footnotes which provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the standard. 1.4 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. 1.5 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. 1.6 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. ====== Significance And Use ====== 5.1 In some situations, penetration through asphalt-based roofing or waterproofing materials by fasteners is a required part of the material installation process or occurs during installation of other system components. When fasteners penetrate the material as a purposeful and planned part of the construction process, it is reasonable to expect that materials designed to limit migration of liquid water at the interface between the penetrating fastener and the material will do so. This qualitative test method provides a means to evaluate the ability of a material to limit water migration at fastener penetrations when tested under defined conditions.
