IEC/TS 62332-1:2011（E）适用于包含固体和液体组件的EIS，其中热应力是主要老化因素，不受电压等级的限制。本部分规定了电气绝缘系统（EIS）热评估和鉴定的双温试验程序。与前一版相比，进行了以下重大技术更改——根据使用第一版中给出的方法进行的广泛测试系列进行了修改。这包括更新预期使用的时间和温度，以获得有用的结果，以及扩大设备范围。 该方法现在可以覆盖使用不同密封系统的电工设备，以及使用搪瓷覆盖电线的设备。

IEC/TS 62332-1:2011(E) is applicable to EIS containing solid and liquid components where the thermal stress is the dominant ageing factor, without restriction to voltage class. This part specifies a dual-temperature test procedure for the thermal evaluation and qualification of electrical insulation systems (EIS). The following significant technical changes with respect to the previous edition have been made - Modifications have been made based on an extensive test series conducted using this methodology given in the first edition. This included updating expected times and tempertatures to use in order to obtain useful results, as well as making the range of equipment covered broader. The method can now cover electrotechnical devices using different sealing systems, as well as devices using enamel covered wires.
