JIS C 2556:1996 English Edition

Methods of measurement of the magnetic properties of magnetic steel sheet and strip by means of a single sheet tester

Abstract

This Japanese Industrial Standard specifies the methods of measurement of core loss characteristics, a.c. magnetizing characteristics and apparent power characteristics of magnetic steel sheets at power frequency by means of a single sheet tester based on H coil method or exciting current method. The magnetic flux density applicable for measurements of core loss characteristics and apparent power characteristics shall be 1.0 T to 1.8 T for grain oriented magnetic steel sheets and 0.8 T to 1.5 T for non-oriented magnetic steel sheets. The applicable magnetic field in the measurement of a.c. magnetizing characteristics shall not exceed 5000 A/m.
