4.6.3.1.2
High
intensity.  U s e item 4 of table VI and subject the
a s s e m b l y to the shock test specified in MIL-STD-810, method 516.2, procedure
I V , figure 516.2-2. Apply three half sine wave shock pulses in each direction
a l o n g the three axes. Peak amplitude shall be 100.0 10.0 g with a time
d u r a t i o n of 1.5 + 0.2 msec measured at the 10 percent amplitude points. At
t h e conclusion of this test, subject the assembly to the performance tests of
4.6.2.
4 . 6 . 3 . 2 V i b r a t i o n .  A p p l i c a t i o n of Vibration A and Vibration B shall be
a s determined by the procurement conditions of 4.5.1 and the first article
c o n d i t i o n s of 4.4.
4 . 6 . 3 . 2 . 1 V i b r a t i o n A .  U s e item 4 of table VI and subject the assembly
t o the vibration test specified in MIL-STD-810, method 514.2 procedure VIII,
e x c e p t that the test level shall be the vibration curve shown in figure 3 and
d u r a t i o n of exposure shall be not less than 80 minutes per axis. At the
c o n c l u s i o n of this test, subject the assembly to the performance tests of
4.6.2.
4.6.3.2.2 V i b r a t i o n B .  This test shall be conducted as in 4.6.3.2.1
e x c e p t that the period of vibration shall be not less than 15 minutes in each
axis.
4 . 6 . 3 . 3 H i g h t e m p e r a t u r e .  S u b j e c t the assembly to the high temperature
t e s t specified. in MIL-STD-810, method 501.1, procedure I. "The highest
o p e r a t i n g temperature shall be 140F.  T h e performance tests of 4.6.2 shall
b e applied.
4 . 6 . 3 . 4 L o w  t e m p e r a t u r e .  S u b j e c t the assembly to the low temperature
t e s t specified in MIL-STD-810, method 502.1, procedure I.  T h e storage
t e m p e r a t u r e shall be -65F.  T h e lowest operating temperature shall be
-25F. The performance tests of 4.6.2 shall be applied.
4 . 6 . 3 . 5 T e m p e r a t u r e c y c l i n g .  W i t h power and loads of figure 2 applied,
subject the assembly to the temperature profile specified in figure 4. At the
c o n c l u s i o n of this test, subject the assembly to the performance tests of
4.6.2.
4 . 6 . 3 . 6 H u m i d i t y .  P l a c e the assembly in a humidity chamber and subject
i t to the humidity test specified in MIL-STD-810, method 507.1, procedure IV.
D u r i n g steps 4, 6 and 8 of procedure IV, subject the assembly to the
performance tests of 4.6.2. After exposure, subject the assembly to the
p e r f o r m a n c e tests of 4.6.2.
