IEC 60404-18:20 25定义了使用超导磁体(SCM)在开路磁路中测量永磁材料的DC磁性的方法的一般原理和技术细节。本方法适用于永磁材料，如IEC 60404？8？1，其性质被假定在其整个体积中是均匀的。有两种方法:-SCM-振动样品磁力计(VSM)方法；-SCM提取方法。该文件还规定了校正试样中自退磁场对在开路磁路中获得的退磁曲线的影响的方法。根据校正的退磁曲线确定磁性。

IEC 60404-18:2025 defines the general principle and technical details of the methods of measurement of the DC magnetic properties of permanent magnet materials in an open magnetic circuit using a superconducting magnet (SCM).
This method is applicable to permanent magnet materials, such as those specified in IEC 60404？8？1, the properties of which are presumed homogeneous throughout their volume.
There are two methods:
- the SCM-vibrating sample magnetometer (VSM) method;
- the SCM-extraction method.
This document also specifies methods to correct the influence of the self-demagnetizing field in the test specimen on the demagnetization curve obtained in an open magnetic circuit. The magnetic properties are determined from the corrected demagnetization curve.
