Applies to grain oriented and non-oriented electrical sheet and
strip for a.c. measurements of magnetic properities at frequencies
up to 400 Hz and for d.c. magnetic measurements. Defines the
general principles and the technical details of the measurement of
the magnetic properties of electrical steel sheet and strip by
means of an Epstein frame. The a.c. magnetic characteristics are
determined for sinusoidal induced voltages, for specified peak
values of magnetic polarization and for a specified frequency.
