自粘胶带.断裂强度和断裂伸长率的测量

[中文适用范围]： 本文件规定了测量自粘胶带在受到足以导致其断裂的拉力时的断裂强度和断裂伸长率的方法。 这些测试方法描述了测试从所提供的自粘胶带卷上切下的 12 毫米或 24 毫米宽样品的程序。 或者，可以直接测试宽达 50 毫米的自粘胶带的原始宽度。 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，由于边缘切割效果更好，结果可能高于商业胶带的结果。 [外文原描述]： 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.
