标准摘要
[中文适用范围]： IEC 60811 第 509 部分给出了绝缘体和护套在高温下的抗开裂性测试程序。 [外文原描述]： IEC 60811-509:2012 gives the procedure for the test for resistance of insulations and sheaths to cracking at an elevated temperature. IEC 60811-509:2012 cancels and replaces Clause 9 of IEC 60811-3-1:1985, which is withdrawn. Full details of the replacements are shown in Annex A of IEC 60811-100:2012.
