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