1.1 本试验方法涵盖了在基本无剥离的标准试样中测试时，用于粘合金属的粘合剂的拉伸剪切强度的测定，该试样产生的粘合剂应力分布代表了典型的低剥离生产型结构接头中产生的应力分布。所达到强度的再现性与是否符合规定的制备和测试条件直接相关。 1.2 以国际单位制表示的值应被视为标准。括号中给出的值仅供参考。 1.3 本标准并不旨在解决与其使用相关的所有安全问题（如果有的话）。 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。 1.4 本国际标准是根据世界贸易组织技术性贸易壁垒委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认的标准化原则制定的。 =====意义和用途====== 4.1 该测试方法旨在为粘合剂的过程控制和规范提供剪切性能数据。 这种测试方法也可能对粘合剂的研究和开发有用。 4.2 搭接剪切性能因试样配置准备、速度和测试环境而异。因此，在需要精确比较结果的情况下，必须仔细控制和报告这些因素。

1.1 This test method covers the determination of the tensile shear strengths of adhesives for bonding metals when tested in an essentially peel-free standard specimen that develops adhesive stress distribution representative of that developed in a typical low-peel production-type structural joint. The reproducibility of the strengths achieved are directly related to conformance with specified conditions of preparation and testing. 1.2 The values stated in SI units are to be regarded as the standard. The values given 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 This test method is designed to produce shear property data for the process control and specification of adhesives. This test method may also be useful for research and development of adhesives. 4.2 Lap shear properties vary with specimen configuration preparation, speed, and environment of testing. Consequently, where precise comparative results are desired, these factors must be carefully controlled and reported.
