4.5.8 Operating temperature.
4.5.8.1 Low temperature. Subject the mounting kit to the low temperature test specified in
MIL-STD-810, method 502.1, procedure 1 to verify conformance to 3.6.1.1. Maintain the
temperature to -6 F for a period of 24 hours. At the conclusion of this time, stabilize the
assembly at the low extreme temperature specified in 3.6.1.1 and perform the test of 4.5.3.
Return the assembly to 73 18 F and perform the tests of 4.5.3.
4.5.8.2 High temperature. Subject the mounting kit to the high temperature test specified in
MIL-STD-810, method 501.1, procedure 1 to verify conformance to 3.6.1.1. Maintain the
temperature at 160 F for a period of 48 hours. At the conclusion of this time, stabilize the
assembly at the high extreme temperature specified in 3.6.1.1 and perform the tests of 4.5.3.
Return the assembly to 73 18 F and perform the tests of 4.5.3.
4.5.8.3 Storage temperature. The mounting kit is to be tested in accordance with the tests of
4.5.8 at the temperature extremes specified in 3.6.1.2 to verify conformance to 3.6.1.2.
4.5.9 Vibration. Mount the mounting kit, using the installed interface configuration for its
intended application, or equivalent, and subject it to the test of MIL-STD-810, method 514.2,
procedure V111 to verify conformance to 3.6.2. Subject the assembly to a sinusoidal vibration
test in accordance with the test level requirements of table I, for a total 180 minutes, in each of
three mutually perpendicular axes. The vibration is to be imposed at a logarithmic sweep rate of
15 minutes per sweep which cycling between 5 to 500 to 5 Hz (during exposure of converter box,
monitor output signal to verify that intermittent operation does not occur). At the conclusion of
this test, examine the assembly for damage and subject it to the performance test of 4.5.3.
4.5.10 Basic shock. Verify conformance to 3.6.3 with the mounting kit mounted, using the
installed interface configuration for its intended application, or equivalent, and subject it to the
test of MIL-STD-810, method 516.2, procedure I. Apply a total of three half sine wave shock
pulses in both directions along each of three mutually perpendicular axes for a total of 18 shocks.
With peak amplitude in accordance with 3.6.3 (during exposure of the converter box), monitor
the output signal of the converter box to verify that intermittent operations does not occur. At
the conclusion of this test, examine the assembly for damage and subject it to the performance test
of 4.5.3.
4.5.11 Ballistic shock. Mount the mounting kit, using the installed interface configuration for
its intended application, or equivalent, and subject it to the test of MIL-STD-810, method 516.2,
procedure VI To verify conformance with 3.6.4. Apply to total of three half sine wave shock
pulses in both directions along each of three mutually perpendicular axes for a total of 18 shocks.
Peak amplitude in accordance with 3.6.4 (during exposure of the converter box), monitor
converter box output signal to verify that intermittent operation does not occur). At the
conclusion of this test, examine the assembly for damage and subject it to the performance tests
of 4.5.3.
