标准摘要
[中文适用范围]： 定义了磁通密度、磁极化和磁场强度的测量方法，以及永磁材料退磁曲线和反冲线的测定方法，例如 IEC 40 中规定的方法 [外文原描述]： Applies to magnetically hard materials only. The described method makes use of a closed loop simulating a ring. Two alternative methods are given for intrinsic coercivity up to and including 600 kA/m and one for materials with higher intrinsic coercivity (e.g. rare earth cobalt alloys).
