磁性材料.第1-1部分:分类.电工钢薄板、带材和叠层板材的表面绝缘

[中文适用范围]： 根据电工钢板、带材和叠片的一般成分、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分类。这些表面绝缘层要么是氧化层，要么是涂层。 [外文原描述]： 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).
