IEC TS 62332-2:2014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，不受电压等级限制。本部分规定了电气绝缘系统（EIS）热评估和鉴定的密封管试验程序。该程序的一个方面是，还提供了一种方法，用于为EIS中同时使用固体和液体成分的材料分配热分类。本程序描述了一种比较老化方法，将牛皮纸和矿物油组成的参考体系与固体和绝缘液体的任何组合的候选体系进行比较。本部分中的试验程序特别适用于浸入式变压器绝缘系统。

IEC TS 62332-2:2014 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 sealed tube test procedure for the thermal evaluation and qualification of electrical insulation systems (EIS). One aspect of this procedure is to also provide a method to assign thermal classifications to materials used in EIS where solid and liquid components are both used. This procedure describes a comparative ageing method whereby a reference system composed of kraft paper and mineral oil is compared to a candidate system of any combination of solid and insulating liquid. The test procedures in this part are specifically applicable to liquid immersed transformer insulation systems.
