Clause Requirement + Test Result - Remark Verdict
TRF No. UL507A
48.6.1 Within 1 minute of cessation of the water spray and
also 30 minutes after cessation of the water spray,
a dielectric voltage withstand test shall be
conducted in accordance with Section 47,
Dielectric Voltage Withstand Test, except that the
duration of the applied potential is to be 15
seconds for the test conducted within 1 minute of
cessation of the water spray test.
N/A
49 Hosedown Test N/A
49.1 When required by 80.1.9, the hosedown test shall
be conducted on a fan.
N/A
49.2 At the conclusion of the test described in 49.3 –
49.5, a fan shall have no standing water inside the
enclosure and there shall be no water on
uninsulated live parts or on film-coated wire, other
than motor windings.
N/A
49.3 For a permanently installed fan that is connected to
conduit during installation, a conduit is to be
installed on the enclosure to equalize internal and
external pressures as required, but it is not to serve
as a drain. No sealing compound other than that
normally provided by the manufacturer is to be
used. The enclosure interior is to be dry.
N/A
49.4 The enclosure and its external mechanisms are
then to be sprayed by water from a hose having a
25.4-mm (1-inch) inside diameter nozzle that
delivers at least 246 L (65 gallons) of water per
minute.
N/A
49.5 For an enclosure having a test length – height plus
width plus depth dimension – of 1.9 m (75 inches)
or less, the duration of the water stream contact
with the enclosure is to be 5 minutes. For an
enclosure having a test length exceeding 1.9 m (75
inches), the duration of water stream contact in
minutes is to be 2.6 times the test length measured
in meters (the test length measured in inches
divided by 15).
N/A
50 Locked Rotor Test P
50.1An impedance-protected motor used in a wall-
insert fan, ceiling-insert fan, a fan intended for use
in cooking areas, or a fan in which the motor is
subjected to conditions such as restricted
ventilation or proximity to an external source of
heat, shall comply with the requirements in 50.5
and 50.6.
