TRF No. UL507A
59.1.2 In a test to determine whether a switch or other
control device complies with the requirements in
59.1.1, the appliance is to be connected to a
grounded supply circuit of rated frequency and
maximum rated voltage in accordance with
46.1.10, with the rotor of the motor locked in
position. During the test, exposed dead metal parts
of the appliance are to be connected to ground
through a 3 ampere plug fuse, and the connection
is to be such that any single-pole, current-rupturing
device is connected in the ungrounded conductor
of the supply circuit. If the appliance is intended for
use on direct current, or on direct current as well as
on alternating current, the exposed dead metal
parts are to be connected so as to be positive with
respect to a single-pole, current-rupturing control
device. The device is to be operated at a maximum
rate of 10 cycles per minute, except that a faster
rate of operation is to be employed only when
agreeable to all concerned.
N/A
59.2 Reversing N/A
59.2.1 A motor-reversing switch shall withstand a test
consisting of 1000 cycles of operation as described
in 59.2.2. There shall be no electrical or
mechanical breakdown of the switch, nor pitting or
burning of the contacts that impairs intended
operation.
N/A
59.2.2 To determine whether a switch complies with the
requirements in 59.2.1, the appliance is to be
connected to a circuit of maximum rated voltage.
Each cycle of operation is to consist of throwing the
switch to the position in which the fan blades rotate
in one direction, allowing the blades to come to full
operating speed in that direction, then – without
pause in any intermediate "off" position unless the
switch does not function otherwise – throwing the
switch to the position in which the rotation of the
blades is reversed, allowing the rotation to attain
normal operating speed in that direction, and then
reversing the direction of rotation again by throwing
the switch to the initial "on" position.

60 Static Load Test For Mounting Means P
60.1 When subjected to the test specified in 60.2 – 60.3,
a cord-connected wall- or ceiling-surface mounted
or direct plug-in appliance shall comply with the
following:
P
a)The security of the attachment of the appliance
to the wall shall not be adversely affected;
