1.1 本试验方法包括在标准试样上以及在规定的制备、调节和测试条件下进行试验时，测定粘合剂的相对剪切强度。本试验方法仅适用于用于将木材与木材粘合的粘合剂。 1.2 以国际单位制表示的数值应视为标准。括号中给出的值仅供参考。 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 根据双层木材结构中使用粘合剂的性质，剪切强度是一个重要的性能标准。 4.2 通过本试验方法测量的剪切强度适用于粘合剂开发、制造质量控制和材料性能规范。

1.1 This test method covers the determination of the comparative shear strengths of adhesives when tested on a standard specimen and under specified conditions of preparation, conditioning, and testing. This test method is intended to be applied only to adhesives used in bonding wood to wood. 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 By the nature of the way adhesives are used in two-ply wood construction, shear strength is an important performance criteria. 4.2 Shear strength measured by this test method is suitable for use in adhesive development, manufacturing quality control, and in materials-performance specifications.
