本文件规定了一种以最小伸长率评估密封剂附着力的方法 根据ISO 8339，方法A或B，在不同基材上的断裂率为25%。这种测试方法可以 适用于单组分和多组分密封剂。这种方法通常用于弹性材料 密封剂，但也可用于塑料密封剂。对于塑料密封剂，测试可能会更加困难和困难 需要由经验丰富的技术人员执行。购买本文件时可获得的所有当前修订均包含在购买本文件中。

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.All current amendments available at time of purchase are included with the purchase of this document.
