本文件规定了当自粘胶带受到足以使其断裂的拉力时，测量其断裂强度和断裂伸长率的方法。这些试验方法描述了从供应的自粘胶带卷上切下的12 mm或24 mm宽样品的试验程序。或者，宽度不超过50 mm的自粘胶带卷可以直接按其原始宽度进行测试。在这些情况下，实际断裂强度和伸长率将是制造商切割边缘的典型值。当测试新切割的样品时，由于边缘切割更好，结果可能高于商业胶带上的结果。

This document specifies methods to measure the breaking strength and elongation at break of a self adhesive tape when it is subjected to a tensile force sufficient to cause it to break.These test methods describe a procedure for testing 12 mm or 24 mm wide samples cut from supplied rolls of self adhesive tapes. Alternatively rolls of self adhesive tape up to 50 mm wide can be directly tested in their original width. In these circumstances the practical breaking strength and elongation will be typical of the manufacturer's cut edges. When newly cut sample pieces are tested, because of the better cutting of the edges, the results can be higher than would be found on commercial tape.
