磁性材料.第8-8部分:单项材料规范.中频下用薄型电工钢带及薄板

[中文适用范围]： IEC 60404 的这一部分定义了标称厚度为 0.05 mm、0.10 mm、0.15 mm、0.20 mm、0.25 mm、0.30 的薄无取向电工钢带和薄板的等级。 mm 和 0.35 mm 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。特别是，它给出了一般要求、磁性能、几何特性和公差、技术特性以及检验程序。注：对于薄的无取向电工钢带和薄板，其他标称厚度（即0.12毫米、0.18毫米、0.23毫米和0.27毫米）可由制造商和买方协商确定。本文件适用于最终退火状态下以卷材或板材形式供应的电工钢带和板材，旨在用于构建主要在 100 Hz 至 10 kHz 频率范围内使用的磁路。 [外文原描述]： 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.
