TRF No. UL507A
61.2 In lieu of conducting the room temperature test
described in 61.2 and 61.3, equipment intended to
be used in cold environments, such as outdoor use
products or fans mounted in a crawl space, shall
be cooled to a temperature of minus 35.0 ±2.0° C
(minus 31.0 ±3.6° F) for outdoor use products and
0° C (32°F) for crawl space or attic mount products
and maintained at this temperature for 3 hours.
While the appliance is still cold, the specimens
shall be subjected to the impact described in 61.2
and 61.3. The conditions for acceptable results are
indicated in 61.4 – 61.6.
P
61.3 An appliance is to be subjected to an impact of
6.67 N (1.5 foot-pounds) on any surface that is
exposed to a blow during intended use. Only one
impact is to be applied at a given point. The impact
is to be produced by dropping a steel sphere, 50.8
mm (2 inches) in diameter and weighing
approximately 0.54 kg (1.18 pounds), from a height
of 381 mm (15 inches). For surfaces other than the
top of an enclosure, the steel sphere is to be
suspended by a cord and allowed to swing as a
pendulum, dropping through a vertical distance of
381 mm. For the test on a freestanding fan, the fan
is to stand in its intended operating position without
restraint.
P
61.4 Following the impact test, the probe illustrated in
Figure 9.1 is to be used to determine whether a
portion of an impeller that presents a risk of injury
to persons is exposed.
N/A
61.5 Deformation of a guard or detachment of a guard
or portion of a guard during the impact test is
acceptable if the part can readily be restored to its
original shape or replaced in the intended manner.
After restoration of the guard, the probe illustrated
in Figure 9.1 shall not contact a portion of an
impeller that can cause risk of injury to persons
when inserted in any opening of the guard.
N/A
61.6 When the guard also serves as an enclosure, the
guard shall be subjected to the impact test
specified in 9.1.3.
N/A
61.7 With reference to 61.5, cracking or denting of the
enclosure shall not affect the function of any safety
controls or constructional features such as
thermostats, overload protective devices,
waterseals, or strain relief.
