Scope

This Standard specifies the method for measuring the magnetic properties of permanent
magnet (magnetically hard) materials using 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 circuit measurement method. The
measurement method for the magnetic properties of permanent magnet materials in a
closed magnetic circuit is specified in GB/T 3217.The comparison of measurement
curves between this Standard and GB/T 3217 for the same test object can be found in
Annex A.
