1.1 本规程涵盖两个程序，适用于使用寿命相对较短的所有粘合剂。其目的是确定工作寿命是否符合稠度测试或粘结强度测试或两者所要求的粘合剂的最低规定工作寿命。 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 为了确定粘合剂的可接受使用寿命，使用了两个程序。本规程旨在适用于: 4.1.1 自含液体或糊状粘合剂， 4.1.2 在使用前需要添加催化剂、硬化剂、填料、稀释剂等的粘合剂，或两种或两种以上此类材料的组合，以及 4.1.3 粉状或片状粘合剂，溶于水或其他溶剂中，用作液体或糊状粘合剂。

1.1 This practice covers two procedures applicable to all adhesives having a relatively short working life. It is intended to determine whether the working life conforms to the minimum specified working life of an adhesive required by consistency tests or by bond strength tests, or by both. 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 To determine acceptable working life of an adhesive, two procedures are used. This practice is intended to apply to: 4.1.1 Self-contained liquid or paste adhesives, 4.1.2 Adhesives requiring addition of a catalyst, hardener, filler, thinner, and so forth, or combinations of two or more of these materials just prior to use, and 4.1.3 Powdered or flaked adhesives which are dissolved in water or other solvent and are used as liquid or paste adhesives.
