Describes the standard 25 cm Epstein frame and associated circuitry,to be used for determining the B-H characteristic (both for d.c. andfor sinusoidal secondary voltage), specific total losses, permeability, and reciprocal of complex permeability. Describes alsothe standard methods for determining resistivity, coefficient of surface insulation resistance, stacking factor, and density.
