磁性材料.第8部分:单项材料规范.第10节:继电器用磁性材料(铁和钢)规范

[中文适用范围]： 本国际标准规定了主要用于继电器的磁性材料的一般要求、磁性能、几何特性和公差以及检验程序。本标准适用于通常以半加工或全加工状态交货的纯铁@非合金钢和合金钢以及铁素体不锈钢产品。这些材料符合 IEC 60404-1 的 A@ B@ C 和 D.3 级要求。 [外文原描述]： IEC 60404-8-10:2009 specifies the general requirements, magnetic properties, geometric characteristics and tolerances as well as inspection procedures for magnetic materials used primarily for relays. This standard applies to pure iron, non-alloyed and alloyed steel and ferritic stainless steel products usually delivered in either the semi-processed or fully-processed state. These materials correspond to classes A, B, C and D.3 of IEC 60404-1. This second edition cancels and replaces the first edition published in 1994 and constitutes a technical revision. The main modifications from the previous edition of the standard are as follows: - introduction of the ferritic stainless steels and the fully-processed state in the scope of the standard (see Clause 1); - modification of the designation with the letter R at the beginning and the condition and state at the end (see Clause 5); - introduction of the new grades R160 and R320 (see Table 2); - modification of the requirements for the heat treatment of test specimens for semi-processed material (see Subclause 8.3.1); - indication in Bibliography of standards referred to in this standard as an information.
