1.1 本试验方法包括测定沥青屋面水泥对潮湿、潮湿或水下表面的附着力。 1.2 以国际单位制或英寸磅单位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。 1.3 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。 1.4 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====== 3.1 该试验方法提供了一种评估用于在不利条件下修复屋顶的沥青屋顶水泥的粘合性能的方法。风化的屋顶表面在干燥时很容易涂上沥青屋顶水泥，但在潮湿或下雨时，沥青屋顶水泥可能不容易粘附在潮湿的表面上，如金属防水板或沥青卷材。本试验方法中使用的火焰金属盖模拟了风化的屋顶表面。

1.1 This test method covers the determination of the adhesion of asphalt roofing cements to damp, wet, or underwater surfaces. 1.2 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. 1.3 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. 1.4 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 ====== 3.1 This test method offers a means of evaluating the adhesive properties of asphalt roofing cements used to repair roofs under adverse conditions. Weathered roof surfaces are easily coated with asphalt roofing cements when they are dry, however when wet or during a rain, asphalt roofing cements may not adhere readily to water-wet surfaces such as metal flashings or asphalt roll roofing. The flamed metal lids used in this test method simulate weathered roof surfaces.
