GB/T 29628-2013 in English

《GB/T 29628-2013永磁（硬磁）脉冲测量方法指南》由TC228（全国电工合金标准化技术委员会）归口，主管部门为中国电器工业协会。
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/T3217中规定。本标准和GB/T3217两种方法对同一测试对象的测量曲线比对参见附录A。

Scope

This standard specifies the method for measuring the magnetic properties of permanent magnet (hard magnetic) materials with a permanent magnet pulse measuring instrument. This standard is applicable to the measurement of magnetic properties of permanent magnet materials with high intrinsic coercivity such as rare earth cobalt and rare earth iron boron. The method specified in this standard is an open magnetic circuit measurement method, and the measurement method for the magnetic properties of permanent magnet materials under a closed magnetic circuit is specified in GB/T 3217. See Appendix A for the comparison of the measurement curves of the same test object between the two methods of this standard and GB/T 3217.
