4.5. 1.1 Temperature, storage condition, The switch shall be subjected
to a temperature of minus 65 plus 5 minus O degrees F for not less than 48 hours.
The temperature shall be raised to plus 160 plus O minus 5 degrees F in not less
than 2 hours and maintained at this temperature for not less than 48 hours. The
unit shall then be subjected to room temperature for not less than 2 hours prior
to performing subsequent tests.
4.3.1.2 Acceleration. The switch, mounted as shown in Figure 6, shall
be subjected to acceleration of 25 plus 2.5 minus Og in the direction shown in
Figure 1 for not less than 4 seconds. Monitor the switch circuits during accel-
eration; the switch circuits shall remain closed during acceleration and there-
after sha11 pass the quality conformance inspection tests.
4.5, 1.3 Vibration, standby condition. The switch, rigidly mounted as
shown in Figure 6, shall be subjected to the vibration tests for Type I equipment
as specified in MIL-STD - 167 up to 25 cps in each of the three axes shown in
Figure 1.
4,5. 1.4 Vibration, operating condition, The switch, rigidly mounted as
shown in Figure 6, shall be subjected to vibration from 20 to 2000 cps at O. 10-
inch doulble amplitude or 10g, whichever is less, along each of three mutually
perpendicular axes. The frequency shall be increased uniformly from 20 to 2000
cps. The frequency shall be traversed in not less than 2.5 minutes, once in
each axis. Monitor the switch circuits during vibration. The switch circuits
shall remain closed during vibration and thereafter shall oass the quality confor-
mance inspection tests.
NOTE: Instrumentation used for the shock test shall not
employ a filter with 3 cut-off frequency below 10 kc.
4,5.1.5 Shock standby condition. Subject the switch to shocks of 40 plus
or minus 4g peak magnitude with a pulse shape approximating a one-half sine
wave having a duration of 5 plus 3 minus O milliseconds. Shocks shall be applied
three times in each direction along each of three mutually perpendicular axes as
shown in Figure 1. Mount the switch in a manner similar to that shown in Fig-
ure 6.
4.5, 1.6 Shock, operating condition. The switch shall be mounted as
shown in Figure 6, and subjected to the following tests.
4.5. 1.6.1 Major. Subject the switch to a shock of 2400 plus or minus
240g peak magnitude. The shock shall have a pulse shape approximating a one-
half sine wave having a duration of 1 plus or minus 0.25 millisecond. Apply the
shock in the direction shown in Figure 1. Thereafter the switch shall pass the
quality conformance inspection tests except for the functioning tests of 4,6.2.3.
