1.1 本试验方法是一种加速实验室程序，用于评估在浸水、循环运动和温度变化的试验配置中建筑密封胶的性能。 3. 1.2 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。 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。 1.4 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。 ====意义和用途====== 5.1 活动接缝中建筑密封胶的失效通常表现为密封胶的内聚失效或密封胶与基材之间的粘合失效，或两者兼而有之。本试验方法中描述的方法仅与使用推荐底漆正确安装时的密封剂性能有关，不评估由不当接缝设计、过度接缝移动、不当应用做法和其他已知导致建筑物和建筑区域密封剂失效的因素引起的密封剂失效。

1.1 This test method is an accelerated laboratory procedure for evaluating the performance of a building sealant in a test configuration that is subjected to water immersion, cyclic movement, and temperature change. 3 1.2 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. 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 ====== 5.1 The failure of a building sealant in an active joint is usually manifested by cohesive failure in the sealant or adhesive failure between the sealant and the substrate, or both. The method described in this test method relates only to the performance of the sealant when properly installed with recommended primers, and does not evaluate sealant failures caused by improper joint design, excessive joint movement, improper application practices, and other factors known to cause sealant failure in buildings and building areas.
