1.1 本试验方法包括在规定的制备、调节和试验条件下，在标准试样上进行试验时，测定胶粘剂剪切时的比较冲击强度。 1.2 以国际单位制表示的数值应视为标准。括号中的值仅供参考。 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====== 4.1 粘合剂可能在突然冲击载荷下失效，而不是在缓慢施加相同或更大力的载荷下失效。 4.2 该测试方法可用于比较各种粘合剂对突然施加的负载的敏感性。

1.1 This test method covers the determination of the comparative impact strength of adhesive bonds in shear, when tested on standard specimens under specified conditions of preparation, conditioning, and testing. 1.2 The values stated in SI units are to be regarded as the standard. The values in parentheses are for information only. 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 ====== 4.1 Adhesives can fail under a sudden impact load and not under a slowly applied load of the same or greater force. 4.2 This test method can be used to compare the sensitivity of various adhesives to suddenly applied loads.
