标准范围

IEC 60404-8-8:20 17(E)定义了标称厚度为0.05 mm、0.10 mm、0.15 mm、0.20 mm、0.25 mm、0.30 mm和0.35 mm的薄无取向电工钢带和薄板以及标称厚度为0.05 mm、0.10 mm、0.15 mm和0.18 mm的薄晶粒取向电工钢带和薄板的等级。特别是，它给出了一般要求、磁性、几何特性和公差、技术特性以及检验程序。笔记？对于薄的无取向电工钢带和薄板，制造商和买方可以商定其他标称厚度（即0.12毫米、0.18毫米、0.23毫米和0.27毫米）。本文件适用于最终退火状态下以线圈或薄板形式供应的电工钢带和薄板，用于构建主要在100 Hz至10 kHz频率范围内使用的磁路。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。

IEC 60404-8-8:2017(E) defines the grades of thin non-oriented electrical steel strip and sheet in nominal thicknesses of 0,05 mm, 0,10 mm, 0,15 mm, 0,20 mm, 0,25 mm, 0,30 mm and 0,35 mm and of thin grain-oriented electrical steel strip and sheet in nominal thicknesses of 0,05 mm, 0,10 mm, 0,15 mm and 0,18 mm. In particular, it gives general requirements, magnetic properties, geometric characteristics and tolerances, technological characteristics, as well as inspection procedures.
NOTE？For thin non-oriented electrical steel strip and sheet, other nominal thicknesses (i.e. 0,12 mm, 0,18 mm, 0,23 mm and 0,27 mm) can be agreed between the manufacturer and the purchaser.
This document applies to electrical steel strip and sheet supplied in the finally annealed condition in coils or sheets and intended for the construction of magnetic circuits predominantly used at frequencies in the range from 100 Hz to 10 kHz.
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.
