1.1 本试验方法涵盖了一种实验室程序，用于测定建筑施工中使用的单组分或多组分就地固化弹性填缝料的强度和剥离特性。 1.2 以国际单位制表示的数值应视为标准值。国际单位制后括号中给出的值仅供参考，不被视为标准值。 1.3 对本标准具有管辖权的委员会不知道其他组织发布的任何可比标准。 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====== 5.1 对于这种剥离试验中的粘附力是否模拟了密封剂在正常使用中遇到的应变和e-拉伸应力类型，与密封剂技术有关的人士存在不同意见。然而，本试验提供了一个有价值的测量方法，用于测量固化密封剂在严重剥离条件下保持与基材粘合的能力。 5.2 许多密封剂制造商利用剥离试验中的粘附力来确定密封剂/底漆组合与不寻常或专有基材的粘附特性。 该测试特别适用于比较同一批密封剂相对于附着力的质量测量，或研究给定密封剂对各种基材的附着力。 5.3 仅此试验方法不适用于比较给定应用中不同密封剂的整体性能。决定给定密封剂在给定应用中是否有用的粘附力也取决于弹性模量和密封剂的应变程度。现有的该试验不考虑弹性模量，也不考虑移动接头中实际密封剂中给定应变产生的应力量。 没有已知的相关性将模量值与剥离值联系起来并应用于剥离值。 5.4 该测试要求结果表明失效模式主要是粘合还是内聚。重要的是要注意，如果粘附值足以应用，则内聚破坏不一定比粘附破坏好。发生粘附失效可以研究粘附力随时间和各种应力条件的变化。

1.1 This test method covers a laboratory procedure for determining the strength and characteristics of the peel properties of a cured-in-place elastomeric joint sealant, single- or multicomponent, for use in building construction. 1.2 The values stated in SI units are to be regarded as standard. The values given in parentheses after SI units are provided for information only and are not considered standard. 1.3 The committee with jurisdiction over this standard is not aware of any comparable standards published by other organizations. 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 ====== 5.1 There are differences in opinion among those concerned with sealant technology whether or not this adhesion-in-peel test simulates the type of strain and e-tensile stresses encountered by a sealant in normal use. Nevertheless, this test provides a valuable measurement of the ability of the cured sealant to maintain a bond to the substrate under severe peel conditions. 5.2 Many sealant manufacturers utilize the adhesion-in-peel test for determining the adhesive characteristics of sealant/primer combinations with unusual or proprietary substrates. This test is especially useful for quality measurements comparing batches of the same sealant relative to adhesion or for studying adhesion of a given sealant to a variety of substrates. 5.3 This test method alone is not appropriate for comparing the overall performance of different sealants in a given application. The adhesive force that determines if a given sealant is useful in a given application also depends on the modulus of elasticity and the degree to which the sealant will be strained. This test, as it exists, does not consider the modulus of elasticity, nor amount of stress that will be produced by a given strain in an actual sealant in a moving joint. No known correlations are given to relate and apply modulus values to the peel values. 5.4 This test requires that the results indicate whether the failure mode is primarily adhesive or cohesive. It is important to note that a cohesive failure is not necessarily better than an adhesive failure, if the adhesive value is sufficient for the application. Having adhesive failure allows one to study the change of adhesion with time and with the various stress conditions.
