IEC 60404-5 Ed. 3.0 b – 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 themagneticflux density, magnetic polarization andthe magneticfieldstrength andalso to determinethe demagnetization curve and recoilline of permanent magnet materials. This edition includes the following significant technicalchangeswith 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.
