1.1 本试验方法描述了测量用于将弹性地板和地毯粘合到选定基材上的粘合剂的剪切强度发展的程序。 1.2 本试验方法提供了一种定量方法，用于测量和记录粘合剂施加到所需基材上时的剪切强度。 1.3 以英寸-磅为单位的数值应视为标准值。括号中给出的值是到国际单位制的数学转换，仅供参考，不被视为标准值。 1.4 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。 1.5 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 在选择或开发弹性地板或地毯粘合剂时，了解粘合剂与所需基材的粘合程度至关重要。剪切载荷模拟常见的失效模式。 4.2 试验方法确定了试验粘合剂和特定基材组合的破坏剪切载荷。

1.1 This test method describes a procedure to measure shear strength development for adhesives used to bond resilient flooring and carpet to selected substrates. 1.2 This test method provides a quantitative means of measuring and recording shear strength of the adhesive when it is applied to the desired substrate. 1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered 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 ====== 4.1 In selecting or developing a resilient flooring or carpet adhesive, it is critical to have knowledge regarding how well the adhesive will bond to the desired substrate. Shear loading simulates a common failure mode. 4.2 The test method determines the failure shear load for the test adhesive and specific substrate combination.
