IEC 60811-405:2012规定了适用于PVC化合物的热稳定性测试程序。IEC 60811-405:2012取消并取代已撤回的IEC 60811-3-2:19 85第9条。IEC 60811-100:2012附录A中显示了替换件的全部详细信息。与上一版本相比没有具体的技术变化，但请参见IEC 60811-100:2012的前言。 本出版物应与IEC 60811-100:2012一起阅读。

IEC 60811-405:2012 specifies the procedure for the thermal stability test which applies to PVC compounds. IEC 60811-405:2012 cancels and replaces Clause 9 of IEC 60811-3-2:1985, which is withdrawn.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.
