Описание
Applies to grain oriented and non-oriented electrical sheet andstrip for a.c. measurements of magnetic properities at frequenciesup to 400 Hz and for d.c. magnetic measurements. Defines thegeneral principles and the technical details of the measurement ofthe magnetic properties of electrical steel sheet and strip bymeans of an Epstein frame. The a.c. magnetic characteristics aredetermined for sinusoidal induced voltages, for specified peakvalues of magnetic polarization and for a specified frequency.This consolidated version consists of the third edition (2000) and its amendment 1 (2008). Therefore, no need to order amendment inaddition to this publication.
