Magnetic materials - Part 5: Permanent magnet (magnetically hard) materials - Methods of measurement of magnetic properties
IEC 60404-5:2015 is to define the method of measurement of the magnetic flux density, magnetic polarization and the magnetic field strength and also to determine the demagnetization curve and recoil line of permanent magnet materials. This edition includes the following significant technical changes with respect to the previous edition:- adaption of the measurement methods and test conditions to newly introduced magnetically hard materials with coercivity values HcJ higher than 2 MA/m;- update of the temperature conditions to allow the measurement of new materials with high temperature coefficients.

Magnetic materials - Part 5: Permanent magnet (magnetically hard) materials - Methods of measurement of magnetic properties
Applies to magnetically hard materials only. The described method makes use of a closed loop simulating a ring. Two alternative methods are given for intrinsic coercivity up to and including 600 kA/m and one for materials with higher intrinsic coercivity (e.g. rare earth cobalt alloys).
