IEC 60404-1-1:2004+AMD1:2024 CSV根据其一般成分、相对绝缘能力和功能对电工钢板、带材和叠片的表面绝缘进行了分类。这些表面绝缘材料要么是氧化层，要么是涂层。这种分类的目的是为各种类型的表面绝缘创建一个术语，并通过提供有关表面绝缘的化学性质和使用的一般信息来帮助表面绝缘的用户。本分类的目的不是根据表面绝缘电阻的具体值来规定绝缘要求。 此类要求由买方和钢铁生产商在适用的情况下达成一致。该分类与冷轧电工钢的各种规范一起使用（见IEC 60404-8系列第2条中的标准）。

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).
