标准摘要
[中文适用范围]： IEC 60811 第 512 部分描述了在高温条件下测试拉伸强度和断裂伸长率的程序。它特定于聚乙烯和聚丙烯化合物。该测试适用于壁厚超过 0@8 mm 的聚烯烃绝缘填充电缆@以及与填充化合物直接接触的聚烯烃护套的样品。 [外文原描述]： IEC 60811-512:2012 describes the procedure for testing tensile strength and elongation at break after conditioning at elevated temperature. It is specific to polyethylene and polypropylene compounds. This test is intended for samples from filled cables, of polyolefin insulations with a wall thickness of more than 0,8 mm and for polyolefin sheaths in direct contact with filling compound. IEC 60811-512:2012 cancels and replaces Clause 8 of IEC 60811-4-2:2004, which is withdrawn. Full details of the replacements are shown in Annex A of IEC 60811-100:2012. There are no specific technical changes with respect to the previous edition, but see the Foreword to IEC 60811-100:2012. This publication is to be read in conjunction with IEC 60811-100:2012 .
