TRF No. UL507A
62.1 When a 88.96-N (20-pound) force is applied for 1
minute over a 50.8-mm (2-inch) diameter area to
any part of the guard of a portable fan or window
fan, spacings to a moving part that presents a risk
of injury to persons shall not be permanently
reduced to the degree that the probe shown in
Figure 9.1 contacts a portion of the moving part
when inserted in any opening in the guard.
P
63 Impeller Test for Portable Fans N/A
63.1 With reference to the requirement in 9.2.12, the
following tests are to be conducted on non-metallic
impellers of portable fans and window fans. A 6.35
mm (1/4 inch) diameter steel rod is to be pushed
suddenly into the blade with the fan resting on the
floor and operating at maximum speed and rated
voltage. A test is to be made with the rod inserted
near the hub, and a second sample is to be tested
with the rod inserted 2/3 of the distance from the
hub to the tip of the blade. The rod is to rest on the
guard as it is inserted. A part of the blade is not to
be thrown more than 1.52 m (5 feet) from the
closest part of the
base of the fan.

64 Impeller Ignition Test N/A
64.1 The requirements in this Section are intended to
investigate the risk of fire for fans as referenced in
the Exception No. 1 (e) of7.4.2.
N/A
64.2 A polymeric impeller that is located outside a
thermally protected motor on a fan that does not
comply with 7.4.2 and Exception No. 1 (a) – (d) of
7.4.2 the shall not ignite as a result of a locked
rotor test conducted as described in 64.3.
N/A
64.3 The motor thermal protector is to be shunted out of
the motor winding so that the motor stays
continually energized. The rotor is to be locked.
The fan is to be positioned as intended in
application and is to be energized in a room
ambient temperature of 10 to 40°C (50 to 104°F) at
the voltage indicated in Table 40.1. The fan is to be
energized until ultimate results are observed, but
no more than 18 days. This procedure is to be
repeated on two additional fan samples.
