标准摘要
[中文适用范围]： IEC 60404-8-8:2017+AMD1:2026 CSV标准规定了标称厚度为0.05 mm、0.10 mm、0.15 mm、0.20 mm、0.25 mm、0.30 mm及0.35 mm的薄型无取向电工钢带和钢片，以及标称厚度为0.05 mm、0.10 mm、0.15 mm和0.18 mm的薄型取向电工钢带和钢片的等级。该标准特别涵盖了通用要求、磁性能、几何特征及公差、工艺特性以及检验程序。注：对于薄型无取向电工钢带和钢片，其他标称厚度（即0.12 mm、0.18 mm、0.23 mm和0.27 mm）可由制造商与买方协商确定。本文件适用于以卷状或片状供应、最终退火状态、主要用于构建磁路且工作频率范围通常在100 Hz至10 kHz之间的电工钢带和钢片。本版与前一版相比，主要技术变更包括：将电工钢的覆盖范围扩展至包括性能更优的等级。 [外文原描述]： IEC 60404-8-8:2017+AMD1:2026 CSV 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.
