1.1 本试验方法是一种实验室程序，通过拉伸和压缩试样，确定单组分弹性体、溶剂释放密封剂在高温和低温下的粘合和内聚性能。 1.2 单位- 以国际单位制或英寸磅单位表示的数值应单独视为标准值。每个系统中所述的值不一定完全相等；因此，为了确保符合标准，每个系统应独立使用，两个系统的值不得合并。 1.3 具有管辖权的小组委员会不知道任何类似的ISO标准。 1.4 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。 有关具体的预防性声明，请参见 注2 . 1.5 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《国际标准、指南和建议制定原则决定》中确立的国际公认标准化原则制定的。 =====意义和用途====== 4.1 在经历移动的接缝中，建筑密封剂的失效表现为密封剂中的内聚失效或密封剂和基底之间的粘合剂失效，或两者兼有。 本试验方法评估了单组分弹性体溶剂释放密封剂在经受运动和温度老化的接缝中的性能。

1.1 This test method is a laboratory procedure that determines the adhesion and cohesion performance of one-part elastomeric, solvent release sealants at high and low temperatures by the extension and compression of test specimens. 1.2 Units— The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined. 1.3 The subcommittee with jurisdiction is not aware of any similar ISO standard. 1.4 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. For a specific precautionary statement, see Note 2 . 1.5 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 The failure of a building sealant in a joint that experiences movement is manifested by cohesive failure in the sealant or adhesive failure between the sealant and substrate, or both. This test method evaluates the performance of one-part elastomeric solvent release sealants in joints subjected to movement and temperature aging.
