标准范围

IEC 60404-8-1:20 15规定了技术上重要的磁性硬材料（永磁体）的主要磁性能和尺寸公差的最小值。仅供参考，IEC 60404的这一部分提供了材料的密度值及其化学成分范围。为了信息和比较的目的，给出了关于磁性材料的一些附加物理数据和机械参考值。与上一版相比，此版本包括以下重大技术变更:a)包括最近开发的各向异性Sm-Fe-N粘结磁体；b)包括具有La和Co作为取代基的高能铁氧体。

IEC 60404-8-1:2015 specifies minimum values for the principal magnetic properties of, and dimensional tolerances for, technically important magnetically hard materials (permanent magnets). For information purposes only, this part of IEC 60404 provides values for the densities of the materials and the ranges of their chemical compositions. Some additional physical data and mechanical reference values concerning the magnetic materials are given for information and comparison purposes. This edition includes the following significant technical changes with respect to the previous edition:
a) recently developed anisotropic Sm-Fe-N bonded magnets are included;
b) high energy ferrites with La and Co as substituents are included.
