following details and exceptions shall apply:
a.
Test condition: A.
b.
Applied force: 15 pounds.
c.
Direction of force: In any direction (including the one most likely to cause failure).

Torque shall be applied to the switch body only.
3/
When method II (high impact) shock is applicable, two additional sample units are required for
submission to sample number one and two tests, using method II for the shock test.
4
If rated for use at altitude, test at rated altitude only.
5/
Test at maximum temperature rating only. If resistive ac load was not required for qualification
inspection (see 3.1), test resistive dc load.
6/
When low level life is specified, the low level life test shall be performed. When low level life is not
specified, the mechanical endurance test shall be performed.
7/
The shielding efficiency test is not required provided the manufacturer has not made any changes in the
design, construction, or material of the switch since the last EMI/RFI shielding efficiency group B
inspection or initial qualification (whichever came later).
8/
On sample 3 and sample 4, applicable only to enclosure 3 and enclosure 4.
9/
Sea level dielectric withstanding voltage test (see 4.7.19) is to be conducted only on those units which
are tested for sea level electrical endurance (see 4.7.28). Altitude dielectric withstanding voltage test
(see 4.7.19) is to be conducted on those units which were tested for altitude electrical endurance tests
(see 4.7.28).
