22.214.171.124.1 Nonoperating. The packed motor (see 5.2) shall be subjected
to free fall drop tests on corners and surfaces of the container. The
packaged unit shall be dropped from a height of 36 inches above an impact
surface which shall be essentially nonyielding stone, concrete, or simi-
lar material. The container, with the packaged unit inside, shall be drop-
ped in sequence on corners 5-1-2, 6-3-4, 5-2-3, and 6-1-4, and side 1 and
face 5 as defined in Figure 2.
126.96.36.199.2 Ready nonoperating and ready. Mount the unpackaged motor on to
a shock test fixture (Figure 1) so that a minimum of 0 percent of table
input of the fixture will be applied to the motor under test. Subject the
motor to shocks listed in Table II, in the conditions specified. Dura-
tion shall be measured by an accelerometer mounted on input table of fix-
ture to indicate applied shock.
188.8.131.52 Acceleration. The motor shall be rigid mounted and subjected
to acceleration magnitudes and directions required by Table III for 1
minute at room temperature for each condition specified.
