A (informative) Epstein frame for use at medium frequencies

Applies to electrical steel sheet and strip for constructing magnetic circuits to be used in the frequency range 400 - 10 000 Hz. Defines three methods for measuring magnetic properties of electrical steel sheet and strip, ie. a.c. measurements made with 25 cm Epstein frame, determining of specific total losses using the wattmeter method and determining magnetic field strength excitation and current and specific apparent power.
