标准摘要
[中文适用范围]： 本部分 IEC 60404 根据电气钢带、钢片和层压板的表面绝缘的一般组成、相对绝缘能力和功能，对其表面绝缘进行分类。这些表面绝缘可以是氧化层或涂层。本分类的目的是为各种类型的表面绝缘创建命名法，并通过提供关于表面绝缘的化学性质和使用的一般信息来帮助用户。本分类不旨在规定特定表面绝缘电阻值的绝缘要求，此类要求由买方和钢铁生产商在适用时商定。本分类与冷轧电工钢的各种规格一起使用（见 IEC 60404-8 系列标准中的第 2 条款）。 [外文原描述]： IEC 60404-1-1:2004+AMD1:2024 CSV establishes a classification of surface insulations for electrical steel sheet, strip and laminations according to their general composition, relative insulating ability and function. These surface insulations are either oxide layers or applied coatings. The purpose of this classification is to create a nomenclature for the various types of surface insulations and to assist users of surface insulations by providing general information about the chemical nature and use of the surface insulations. It is not the intent of this classification to specify insulation requirements in terms of specific values of surface insulation resistance. Such requirements are agreed between the purchaser and the steel producer, where applicable. The classification is used in conjunction with the various specifications for cold rolled electrical steels (see the standards in the IEC 60404-8 series in Clause 2).
