标准摘要
[中文适用范围]： IEC 60404 这部分的目的是定义磁通量密度@磁极化和磁场强度的测量方法，并确定永磁材料@（如 IEC 60404 中规定的那些）的退磁曲线和反冲线-8-1 [1] 1@ 假定其整个体积的特性是均匀的。磁系统的性能不仅取决于永磁材料的特性，还取决于系统、气隙和磁路其他元件的尺寸。 IEC 60404 本部分中描述的方法是指闭合磁路中磁性能的测量。 [外文原描述]： IEC 60404-5:2015 is to define the method of measurement of the magnetic flux density, magnetic polarization and the magnetic field strength and also to determine the demagnetization curve and recoil line of permanent magnet materials. This edition includes the following significant technical changes with respect to the previous edition: - adaption of the measurement methods and test conditions to newly introduced magnetically hard materials with coercivity values HcJ higher than 2 MA/m; - update of the temperature conditions to allow the measurement of new materials with high temperature coefficients.
