Exception: The power input of an appliance that
uses a positive temperature coefficient (PTC)
heating element shall be measured 1 minute after
it has become energized

All appliances
P
44.1.1
An appliance tested under the conditions
described in this test shall not attain temperature
rises at any time during the test greater than those
indicated in Table 44.1
P
Exception: An initial peak temperature transient
or the peak temperatures measured during
preheat cycles not exceeding the temperature rise
values specified in Table 44.1 by more than 20
percent are acceptable. If temperature excursions
exceed the temperature rise values in Table 44.1
by more than 20 percent, the equivalent
continuous normal use temperature is to be
determined as described in
44.1.22. The equivalent continuous normal use
temperature rises shall not exceed the values
specified in Table 44..1
P
44.1.2
A temperature control that under intended
operating conditions is relied upon to maintain
temperatures within the limits specified in Tables
44.1 and 44.2, shall comply with the requirements
in54.2.1 for a combination temperature-limiting
and temperature-regulating control
P
44.1.3
At coils, the preferred method of measuring
temperatures is the thermocouple method;
temperature measurements by either the
thermocouple or change-of-resistance method
may be used. When temperatures of a coil or
winding are measured by means of
thermocouples, they are to be mounted on the
outside of the coil wrap. If the coil is inaccessible
for mounting thermocouples (for example, a coil
immersed in sealing compound) or if the coil wrap
includes thermal insulation such as more than 1/32
inch (0.8 mm) of cotton, paper, rayon, or similar
insulation, the change of resistance method is to
be used. For the thermocouple-measured
temperature of a coil of an alternating-current
motor (other than a universal motor) having a
frame diameter of 7 inches (178 mm) or less
(Table 44.1, item A, subitems 2 and 4), the
thermocouple is to be mounted on the integrally
applied insulation of the conductor

In using the resistance method, the windings are
to be at room temperature at the start of the test.
The temperature rise of a winding is to be
calculated from the formula:
