69.3 Each sample is to consist of a length of power-
supply cord to which the tag has been applied. The
power-supply cord, with the attachment plug
pointing up, is to be held tautly in a vertical plane.
A force of 5 lbf (22.2 N) is to be applied for one
minute to the upper-most corner of the tag farthest
from the power- supply cord, within 1/4 in (6.4 mm)
of the vertical edge of the tag. The force is to be
applied vertically downward in a direction parallel
to the major axis of the cord. In determining
compliance with 69.1 (d), manipulation is
permissible, such as straightening of the tag by
hand. To determine compliance with
69.1 (d), each sample is to be scraped 10 times
across printed areas and edges, with a force of
approximately 2 lbf (8.9 N), using the edge of a
5/64-in (2.0-mm) thick steel blade held at a right
angle to the test surface.

70 Drop Test N/A
70.1 A desk fan and a box fan shall withstand, with the
fan operating at maximum speed, the drop test
described in 70.2.
N/A
70.2 Each of three samples of a fan is to be dropped
through a distance of 914.40 mm (3 feet) to strike a
hardwood surface. Each sample is to be dropped
three times. Three samples shall be employed for
the test; however, if the manufacturer so elects,
fewer samples may be used in accordance with
Figure 70.1. As a result of the drop test, the probe
illustrated in Figure 9.1 shall not be able to 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
70.3 The hardwood surface mentioned in 70.2 is to
consist of a layer of 19-mm (3/4-inch) thick tongue-
and-groove oak flooring mounted on two layers of
19-mm (3/4-inch) thick plywood. The assembly is to
rest on a concrete floor during the test.
N/A
70.4 All samples are to be supported on a surface
914.40 mm (3 feet) above the hardwood surface.
Each sample is to be dislodged from the supporting
surface by a sudden pull applied to the power-
supply cord in a plane parallel to the supporting
surface and twice by being pushed by a force
parallel to the mounting surface applied to the top
of the sample, which is to be placed at the edge of
the supporting surface. The sample is to be
oriented differently for each test.
