47.4 To determine whether an appliance complies with
the requirements in 47.1, it is to be tested using a
500-volt-ampere or larger capacity transformer, the
output voltage of which can be varied. The applied
potential is to be increased from zero to the
required test value and is to be held at that level for
1 minute. The increase in applied potential is to be
at a substantially uniform rate as rapid as is
consistent with correct indication of its value by a
voltmeter.

47.5 The test equipment for conducting the dielectric
voltage-withstand test is to be adjusted for
sensitivity such that when a resistor of 120,000
ohms is connected across the output, the test
equipment does not indicate unacceptable
performance for any output voltage less than the
specified test voltage, and the test equipment does
indicate unacceptable performance for any output
voltage equal to or greater than the specified test
value. The resistance of the calibrating resistor is to
be adjusted as close to 120,000 ohms as
instrument accuracy can provide, and not more
than 120,000 ohms.

a)Between the stator winding and the shading
coils; or

b)Between the shading coils and the stator core,
with the appliance at the temperature reached in
intended use.
