Clause Requirement + Test Result - Remark Verdict
TRF No. UL507A
70.5 Deformation of a guard or detachment of a guard
or portion of a guard during the drop test is
acceptable when the part (including ribs of a desk
fan) can readily be restored to its original shape or
a detached guard can be readily replaced in the
intended manner. After restoration of the guard, the
probe illustrated in Figure 9.1 shall not contact a
portion of a blade or blower wheel that presents a
risk of injury to persons when inserted in any
opening in the guard.
N/A
70.6 A part of the blade shall not be thrown more than
1.52 m (5 feet) from the closest part of the base of
the fan.

71 Security of Handle Test N/A
71.1 A handle used to support or carry a fan shall
withstand a force of four times the weight of the fan
without breakage of the handle.
N/A
71.2 To determine if a handle complies with the
requirements in 71.1, the force is to be started at
zero and gradually increased so that the force
specified in 71.1 is attained in 5 to 10 seconds and
maintained for 1 minute. When the handle is 76.20
mm (3 inches) or more in width, the force is to be
uniformly distributed over a 76.20-mm width at the
center of the handle without clamping. When the
width is less than 76.20 mm, the force is to be
distributed over the entire handle. When more than
one handle is furnished on a fan and the fan
cannot be carried by only one handle, the force is
to be distributed between the handles. The
distribution of forces is to be determined by
measuring the percentage of the fan weight
sustained by each handle with the fan in the
intended carrying position. When a fan is furnished
with more than one handle and can be carried by
only one handle, each handle is to sustain the total
force.
N/A
72 Stability Test N/A
72.1 A cord-connected freestanding appliance shall not
tip over when placed on a plane inclined 10
degrees from the horizontal.
