4.6.2.4 Fail lamp diodes. Use items 1, 2 and 5 of table VIII or suitable
equipment to verify the requirements of 3.3.4.
4.6.3 Environmental tests.
4.6.3.1 Shock.
4.6.3.1.1 Basic design. Use items 3, 4 and 6 of table VIII or mount the
assembly in a suitable shock fixture and subject it to the shock test
specified in MIL-STD-810, method 516.2, procedure 1, figure 516.2-2. Apply
three half sine wave shock pulses in each direction along the three axes.
Peak amplitude shall be 50 5 g with a time duration of 18 3 msec measured
at the 10 percent amplitude points. At the conclusion of this test, subject
the assembly to the performance tests of table V.
4.6.3.1.2 High intensity. Use items 3, 4 and 6 of table VIII or mount
the assembly in a suitable shock fixture and subject it to the shock test
specified in MIL-STD-810, method 516.1, procedure IV, figure 516.2-2. Apply
three halt sine wave shock pulses in each direction along the three axes.
Peak amplitude shall be 125 12.5 g with a time duration of 0.6 0.2 msec
measured at the 10 percent amplitude points. The tolerance shall be 0.2
msec on the first shock for each direction set up and 0.1 msec for
subsequent shocks for each direction set up when the specified pulse duration
is 1.0 msec or less. At the conclusion of this test, subject the assembly to
the performance tests of table V.
4.6.3.2 Vibration. Vibration A as specified in 4.6.3.2.1 shall be
conducted only for first article inspection. Vibration B as specified in
4.6.3.2.2 shall be conducted only for qualify conformance inspection.
4.6.3.2.1 Vibration A. Use items 3, 4 and 6 of table VIII or mount the
assembly in a suitable vibration fixture and subject the assembly to the
vibration test specified in MIL-STD-810, method 514.2 procedure VIII, except
that the test level shall be the vibration curve shown in figure 1 and
duration of exposure shall be not less than 80 minutes per axis. At the
conclusion of this test, subject the assembly to the performance tests of
table III.
4.6.3.2.2 Vibration B. This test shall be conducted as in 4.6.3.2.1
except that the period of vibration shall be not less than 15 minutes in each
axis.
