1.1 本试验方法涵盖了测定预成型胶带密封剂拉伸粘合强度的实验室程序。可以确定失效的类型，并且可以估计内聚/粘合失效的程度。 1.2 以公制（SI）单位表示的值应被视为标准。括号中给出的值仅供参考。 1.3 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。 1.5 本国际标准是根据关于制定国际标准、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世界贸易组织技术性贸易壁垒（TBT）委员会发布的离子。 ======意义和用途====== 5.1 预成型带密封剂是粘性的、可变形的固体，其在两个或更多个基材之间的压缩下用于各种密封应用中，其中表面可以是相似或不同的材料。该程序测量预成型带密封剂的拉伸强度。它还提供了预成型带密封剂的内聚性质和粘合性质的指示。本程序并非旨在模拟实际使用条件。

1.1 This test method covers a laboratory procedure for determining the tensile adhesive strength of a preformed tape sealant. The type of failure can be determined, and the degree of cohesive/adhesive failure can be estimated. 1.2 The values stated in metric (SI) units are to be regarded as the standard. The values given in parentheses are provided for information purposes only. 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. 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 ====== 5.1 Preformed tape sealants are tacky, deformable solids, that are used under compression between two or more substrates, in various sealing applications where the surfaces may be of similar or dissimilar materials. This procedure measures the tensile strength of the preformed tape sealant. It also provides an indication of the cohesive nature and adhesive bonding properties of the preformed tape sealant. This procedure is not intended to simulate actual use conditions.
