标准摘要
[中文适用范围]： 该文件规定了一种评估最小断裂伸长率为 25% 的密封剂在各种基材上的附着力的方法（根据 ISO 8339，方法 A 或 B）。 该测试方法可用于单组分和多组分密封剂。 该方法通常用于弹性密封剂，但也可用于塑料密封剂。 对于塑料密封胶，测试可能更加困难，需要由经验丰富的技术人员进行。 该测试用于判断建筑密封剂与清洁剂、活化剂和/或底漆结合使用时在剥离力下以及在不同老化条件下在各种基材上的粘附力。 根据本文件进行的附着力测试也可用于生产过程监控和质量保证。 本文件中描述的测试方法无意取代 ISO 11600 中指定的任何粘合内聚力测试方法。 [外文原描述]： The document specifies a method for evaluating the adhesion of sealants with a minimum elongation at break of 25 % (according to ISO 8339, Method A or B) on various substrates. This test method can be used for one-component and multi component sealants. This method is typically used for elastic sealants but can be also used for plastic sealants. For plastic sealants, the test can be more difficult and needs to be carried out by experienced technicians. This test is used to judge the adhesion of construction sealants in combination with cleaners, activators and/or primers on various substrates when exposed to a peeling force and also after different aging conditions. An adhesion test according to this document can also be conducted for process monitoring and quality assurance accompanying production. The test method described in this document is not intended to replace any adhesion cohesion test methods specified in ISO 11600.
