标准摘要
[中文适用范围]： IEC 60404 的这一部分定义了标称厚度为 0.35 mm、0.50 mm、0.65 mm 和 1.00 mm 的冷轧无取向电工钢板和钢带的等级。它特别规定了一般要求、磁性能、几何特性和公差、技术特性以及检验程序。注：本标准在附录 A 中给出了厚度为 0.47 毫米的电工板材和带材在 50 Hz 和 60 Hz 时的磁性能。本标准适用于在完全退火状态下供应的用于构建磁路的材料。它不适用于半加工材料。这些磁性材料符合 IEC 60404-1 的 C21 条款。 [外文原描述]： Defines the grades of cold-rolled non-oriented electrical steel sheet and strip in nominal thicknesses of 0.35 mm, 0.50 mm, 0.65 mm and 1,00 mm. Specifies general requirements, the magnetic properties, geometric characteristics and tolerances, and technological characteristics, as well as the inspection procedure. Applies to materials supplied in the fully annealed condition intended for the construction of magnetic currents. Does not apply to semi-processed material.
