标准摘要
[中文适用范围]： 本国际标准列出了对已建立的电气绝缘系统 (EIS) 的热分类进行修改的资格所需的测试程序。本标准适用于绕线电工设备中使用的EIS。测试程序是比较性的，因为候选 EIS 的性能与参考 EIS@ 的性能进行比较，参考 EIS@ 具有根据 IEC 60505 经过验证的服务经验或已通过 IEC 61857 系列中给出的程序之一进行了评估。 [外文原描述]： IEC 61858:2008 lists the required test procedures for qualification of modifications of an established electrical insulation system (EIS) with respect to its thermal classification. This standard is applicable to EIS used in wire-wound electrotechnical devices. The test procedures are comparative in that the performance of a candidate EIS is compared to that of a reference EIS, which has proven service experience in accordance with IEC 60505 or has been evaluated by one of the procedures given in the IEC 61857 series. This third edition cancels and replaces the second edition, published in 2004 by IEC TC 98: Electrical insulation systems (EIS). It constitutes an editorial revision.
