This standard specifies the methods for measuring magnetic properties of permanent (magnetically hard) materials using pulsed field magnetometers.
This standard is applicable to the measurement of the magnetic properties of permanent materials with high intrinsic coercivity like rare earth cobalt and Re-Fe-B.
The methods of measurement of the magnetic properties of magnetically hard material have been specified in this standard for open magnetic circuit and in GB/T 3217 for closed magnetic circuit. The measurement curve comparison of the same testee at the methods in this standard and GB/T 3217 is detailed in Appendix A.
