Guides for methods of measurement of the magnetic properties of permanent(magnetically hard) materials by pulsed field magnetometry
NEQ IEC TR 62331:2005
全国电工合金标准化技术委员会(SAC/TC 228)
本标准规定了用永磁脉冲测量仪测量永磁（硬磁）材料磁性能的方法。
本标准适用于稀土钴、稀土铁硼等内禀矫顽力较高的永磁材料的磁性能测量。
本标准规定的方法是一种开磁路测量方法，永磁材料磁性能在闭合磁路下的测量方法在GB/T 3217中规定。本标准和GB/T 3217两种方法对同一测试对象的测量曲线比对参见附录A。
