新的！IEC 60404-8-7:20 17作为IEC 60404-8-7:20 17 RLV提供，其中包含国际标准及其红线版本，显示了与上一版本相比技术内容的所有变化。IEC 60404-8-7:20 17定义了标称厚度为0.23毫米、0.27毫米、0.30毫米和0.35毫米的冷轧取向电工钢带和板材的等级。特别是，它给出了一般要求、磁性、几何特性、公差和工艺特性，以及检验程序。本文件适用于在最终退火状态下以线圈或薄板形式供应的戈斯织构晶粒取向电工钢带和薄板，用于磁路的构造。成绩分为两类:-常规等级；-高渗透性等级，包括可以在域精制条件下递送的等级。它们对应于IEC 60404-1的C22级。第四版取消并取代了2008年出版的第三版。本版构成技术修订版。与上一版相比，此版本包括以下重大技术变更:-扩大电工钢的范围以包括改进的等级。

NEW!IEC 60404-8-7:2017 is available as IEC 60404-8-7:2017 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.

IEC 60404-8-7:2017 defines the grades of cold-rolled grain-oriented electrical steel strip and sheet in nominal thicknesses of 0,23 mm, 0,27 mm, 0,30 mm and 0,35 mm. In particular, it gives general requirements, magnetic properties, geometric characteristics, tolerances and technological characteristics, as well as inspection procedures. This document applies to Goss textured grain-oriented electrical steel strip and sheet supplied in the final annealed condition in coils or sheets, and intended for the construction of magnetic circuits.
The grades are grouped into two classes:
– conventional grades;
– high permeability grades, including grades which may be delivered in the domain refined condition. They correspond to Class C22 of IEC 60404-1.
This fourth edition cancels and replaces the third edition published in 2008. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
– extension of the range of electrical steels to include the improved grades.
