Exception: In the case of a hand-held appliance
having a mass of 1/2 pound (227 g) or less,
exclusive of the cord, the pull applied to the cord
shall be 20 pounds force (89 N)
P
48.2
The connections of the cord inside the appliance
are to be disconnected. The specified force is to
be applied to the cord and so supported by the
appliance that the strain relief means will be
stressed from any angle that the construction of
the appliance permits. At the point of
disconnection of the conductors, there shall not be
movement of the cord to indicate that stress on the
connections would have resulted

Cord Flexing Test
P
49.1
Each of six as received samples of a
hand-supported hair-drying appliance (such as a
hair dryer, blower-styler, heated air comb or brush,
hair dryer-curling iron combination, wall- hung hair
dryer, or the hand unit of a wall- mounted hair
dryer), comb, curling iron, untangler, hair crimping
iron, hair straightening iron, or similar hand-
supported appliance shall be subjected to a cord
flexing test as described in 49.2. Three additional
samples of a hand- supported hair-drying
appliance shall be subjected to the conditioning
and flexing test described in 49.6
P
49.2
Each sample is to be mounted in a guide with a
1/4 pound (113 g) weight attached to the cord 8
inches (203 mm) from the cord entry hole so that
the unit can be rotated 540 degrees about the
axial center of the cord. A typical arrangement is
shown in Figure 49.1. The rate of flexing is to be
10 cycles per minute, where 1 cycle is equivalent
to three complete rotations as defined in Note (a)
of Table 49.1, resulting in a rotational speed of 30
rotations per minute. During the test, the supply
cord conductors of the sample are to carry current
equal to the current rating of the appliance at rated
voltage. The as
received samples are to be subjected to the
number of cycles of flexing specified in Table
49.1. The conditioned samples of a hand-
supported hair-drying appliance are to be
subjected to 1,000 cycles of flexing
P
Exception No. 1: With the concurrence of all
concerned, the attached weight may be other than
1/4 pound, adjusted such that the cord is held taut
and the intended flexing action is produced
P
49.3
For an appliance using a cord swivel construction,
the test described in 49.2 is to be conducted with
the swivel locked in place
P
Exception: An appliance using a cord swivel
construction can be tested with the swivel
operating provided it complies with 49.5
