IEC 60404-1:20 16可作为IEC 60404-1:20 16获得包含国际标准及其红线的RLV版本，显示技术内容与上一版。IEC 60404-1:20 16(E)旨在对市售磁性材料进行分类。术语“磁性材料”表示其中应用需要存在铁磁性或亚铁磁性的物质。磁性材料的分类基于普遍公认的两类主要产品的存在:-软磁性材料(矫顽力小于或等于1000A/m)；-硬磁性材料(矫顽力大于1000A/m)。与上一版相比，此版本包括以下重大技术变更:a)删除描述材料典型特性的所有表格和数值，以符合文件作为分类而非规范的目的。b)扩大E1和E3类的Ni含量。c)增加F3类的Co含量。d)添加新类别:U5键合稀土-铁-氮磁体。
IEC 60404-1:2016 is available as
IEC 60404-1:2016(E) is intended to classify commercially available magnetic materials. The term "magnetic materials" denotes substances where the application requires the existence of ferromagnetic or ferrimagnetic properties. The classification of magnetic materials is based upon the generally recognized existence of two main groups of products:
- soft magnetic materials (coercivity less than or equal to 1 000 A/m);
- hard magnetic materials (coercivity greater than 1 000 A/m). This edition includes the following significant technical changes with respect to the previous edition:
a) Removal of all tables and values describing typical properties of the material to be consistent with the aim of the document to be a classification and not a specification.
b) Enlargement of the Ni content for the classes E1 and E3.
c) Enlargement of the Co content for the classes F3.
d) Addition of a new class: U5 bonded rare earth-iron-nitrogen magnets.
