标准摘要
[中文适用范围]： IEC 60404-1:2016+AMD1:2025 CSV 的目的是对商用磁性材料进行分类。“磁性材料”一词指的是在应用中需要具有铁磁性或亚铁磁性特性的物质。磁性材料的分类基于普遍公认的两大类产品：软磁材料（矫顽力小于或等于 1 000 A/m）；硬磁材料（矫顽力大于 1 000 A/m）。与前一版相比，本版包含了以下重大技术变更：a) 删除所有描述材料典型特性的表格和数值，以符合本文件作为分类标准而非规格标准的目标；b) 扩展 E1 和 E3 类中镍（Ni）含量的范围；c) 扩展 F3 类中钴（Co）含量的范围；d) 新增一个类别：U5 类粘结稀土-铁-氮磁体。 [外文原描述]： IEC 60404-1:2016+AMD1:2025 CSV 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.
