1.1 本试验方法描述了一种实验室程序，用于测量密封剂在承受由施加的规定应变产生的拉伸载荷时的粘附/内聚性能。在浸水之前、浸水期间和浸水之后，评估粘附/内聚性能。 1.2 本试验方法检查了在相当于应变/移动能力倍数的应变下，密封剂在指定基材上的粘合和内聚性能（等级符合规范要求 C920 )制造商根据规范为给定密封剂指定 C920 . 1.3 以国际单位制表示的数值应视为标准值。 国际单位制后括号中给出的值仅供参考，不被视为标准值。 1.4 可比测试- 其他类似测试为ISO 10590和8340。 1.5 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。 1.6 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》中确立的国际公认标准化原则制定的。 ====意义和用途====== 5.1 在任何密封剂应用中，当在其预期使用寿命内保持应变时，密封剂必须能够保持与基材的粘合。 5.2 该测试方法是密封剂在应变下粘附到给定基材的能力的指标。 5.3 默认测试应变是移动能力（等级符合规范要求 C920 )制造商指定的密封剂。默认关节配置为12.7 mm×12.7 mm×50.8 mm( 1. / 2. 在里面通过 1. / 2. 在里面2英寸）。如第节所述，可以使用和报告其他应变和接头配置 8. 和 表1 .

1.1 This test method describes a laboratory procedure for measuring the adhesion/cohesion properties of a sealant when subjected to tensile loads resulting from an applied specified strain. The adhesion/cohesion properties are evaluated before, during, and after water immersion. 1.2 This test method examines the adhesive and cohesive performance of a sealant on a specified substrate at a strain equivalent to a multiple of the strain/movement capability (Class in accordance with Specification C920 ) designated by the manufacturer for the given sealant in accordance with Specification C920 . 1.3 The values stated in SI units are to be regarded as standard. The values given in parentheses after SI units are provided for information only and are not considered standard. 1.4 Comparable Tests— Other comparable tests are ISO 10590 and 8340. 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 any sealant application, the sealant must be capable of maintaining an adhesive bond to the substrate when held in strain for its intended service life. 5.2 This test method is an indicator of a sealant’s ability to adhere under strain to a given substrate. 5.3 The default test strain is the movement ability (Class in accordance with Specification C920 ) of the sealant as designated by the manufacturer. The default joint configuration is 12.7 mm by 12.7 mm by 50.8 mm ( 1 / 2 in. by 1 / 2 in. by 2 in.). Other strains and joint configurations may be used and reported as noted in Section 8 and Table 1 .
