标准摘要
[中文适用范围]： 规定了电气绝缘系统 (EIS) 热评估和鉴定的一般测试程序，并建立了将候选 EIS 的性能与参考 EIS 的性能进行比较的程序。该基本标准适用 [外文原描述]： Specifies a general test procedure for the thermal evaluation and qualification of electrical insulation systems (EIS) and establishes a procedure that compares the performance of a candidate EIS to that of a reference EIS. This basic standard is applicable to existing or proposed EIS used in electrotechnical products with an input voltage of up to 1 000 V where the thermal factor is the dominating ageing factor. This second edition cancels and replaces the first edition published in 1998, and constitutes a technical revision to make this basic standard compatible with parts 21 and 22.
