4.6.2.8 Pulse forming network (PFN) low charge voltage. Use item 1 of
table VII or suitable equipment to determine compliance with 3.3.8.
4.6.2.9 Computer ON characteristics. Use item 1 of table VII a suitable
equipment to determine compliance with 3.3.9.
4.6.3 Environment tests.
4.6.3.1 Shock.
4.6.3.1.1 Basic design. Use items 2, 3 and 4 of table VII or mount the
assembly in a suitable shock fixture and subject it to the shock test
specified in MIL-STD-810, method 516.2, procedures I, figure 516.2. Apply
three half sine wave shock pulses is each direction along the three axes.
Peak amplitude shall be 40 4 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 IV.
4.6.3.1.2 High incensity. Use item 4 of table VII or mount the assembly
in a a suitable shock fixture and subject it to the shock test specified in
MIL-STD-810, method 516.2, procedure IV, figure 516.2-2. Apply three half
sine wave shock pulses in aach direction along the three axes. Peak amplitude
shall be 100.0 + 10.0 g with a time duration of 1.5 0.2 msec measured at the
10 percent amplitude points. At the conclusion of this test, subject the
assembly to the performance tests of table IV.
4.6.3.2 Vibration. Vibration A as specified in 4.6.3.2.1 shall be
conducted only for first article inspection. Vibration a specified in
4.6.3.2.2 shall be conducted only for quality conformance inspection.
4.6.3.2.1 Vibration A. Use items 3 and 4 of table VII or mount the
assembly in a suitable vibration fixture end 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 4 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 IV.
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.
4.6.3.3 High temperature. Use items 5 and 6 of table VII or suitable
equipment and subject the assembly to the high temperature test specified in
MIL-STD-810, method 501.1, procedure 1. The highest operating temperature
shall be 140F. the performance tests of table IV shall be l pplied.
