44.1.19
An electrical heating element intended for
application to the hair is to be loaded with a
moistened cloth and then operated until the
moisture has been evaporated and the heating
surface of the unit has attained a temperature of
204°C (400°F). Following a 2 minute period with
the unit disconnected, during which it is to be
reloaded with another moistened cloth, the heating
and evaporating operation is to be conducted a
second time. The complete cycle is then to be
repeated again. Temperatures are to be
measured throughout the test.
N/A
44.1.20
An appliance having a reservoir for heating water
shall have the water temperature measured by
means of a thermocouple floated approximately
3/16 inch (4.8 mm) beneath the surface of the
solution and located midway between the outer
surface of the electrode enclosure and the inner
surface of the water reservoir. The unit is to be
tested in a room ambient of 25°C (77°F)
N/A
Exception: This requirement does not apply to
electrode-type appliances with a water reservoir or
boiling chamber having a capacity of 8 ounces
(23.7 mL) or less and marked in accordance with
83.2
N/A
44.1.21
For an appliance in which clips to be applied to the
hair are heated by an external heater, the test is to
consist of operation of the appliance until
temperatures are constant, with the clips in place
on the heater

44.1.22
With regard to the Exception to 44.1.1, the
equivalent continuous normal use temperature is
to be determined as follows. The graph of the
temperature plotted against time from the start of
the test until a stabilized condition has been
established is to be obtained, and the area under
the curve over the period of time, ts minus t0, is to
be determined. Figure 44.1 shows t0 as the time
when the graph first crosses the line, TI, and ts as
the time when a stabilized temperature is
obtained. (TI represents the temperature index or
the temperature acceptable for the material or
component in question.) The area under the
curve, divided by the period of time (ts minus t0),
will yield the equivalent continuous normal use
temperature. The area under the curve may be
determined mathematically (Simpson’s Rule),
graphically, or by using a planimeter
