IEC 60811-508:2012+A1:2017给出了高温压力测试的程序，该程序通常适用于用于绝缘材料和护套材料的热塑性化合物。IEC 60811-508:2012取消并取代已撤回的IEC 60811-3-1:19 85第8条。IEC 60811-100:2012附录A中显示了替换件的全部详细信息。与上一版相比的重大技术变更如下: -重新陈述烘箱的特性，特别是与防振和温度控制有关的特性； -加强了扁平电缆的制备和测试的细节； -关于厚度和尺寸测量的增强细节。另见IEC 60811-100:2012的前言。 本出版物应与IEC 60811-100:2012一起阅读。该合并版本由第一版（2012年）及其修正案1（2017年）组成。因此，除本出版物外，无需下令修订。

IEC 60811-508:2012+A1:2017 gives the procedure for a pressure test at high temperature, which typically applies to thermoplastic compounds used for insulating and sheathing materials. IEC 60811-508:2012 cancels and replaces Clause 8 of IEC 60811-3-1:1985, which is withdrawn. Full details of the replacements are shown in Annex A of IEC 60811-100:2012. Significant technical changes with respect to the previous edition are as follows:
- re-statement of oven characteristics, especially relating to anti-vibration and to temperature control;
- enhanced detail as to the preparations and testing of flat cables;
- enhanced detail as to thickness and dimensional measurements. See also the Foreword to IEC 60811-100:2012.
This publication is to be read in conjunction with IEC 60811-100:2012. This consolidated version consists of the first edition (2012) and its amendment 1 (2017). Therefore, no need to order amendment in addition to this publication.
