MIL-DTL-83739D
4.7.8 Temperature shock (see 3.6.8). Switches shall be placed within a test chamber wherein the highest
specified temperature (see 3.1) is maintained. Unless otherwise specified, switches shall be exposed to this
temperature for a period of 4 hours; at the conclusion of this time and within 5 minutes, unless otherwise specified,
the switches will be transferred to a chamber having the lowest specified temperature (see 3.1) for a period of
4 hours. This constitutes one cycle of temperature shock. Switches shall be non-operating for the entire exposure.
Three complete cycles shall be performed on a continuing basis. However, either the high or the low temperature
soak periods can be extended to an overnight period to prevent interruption of the transfer sequence. After the test,
the switches shall be subjected to the individual tests of group I in table III.
4.7.9 Vibration (see 3.6.9). Switches shall be tested in accordance with MIL-STD-202, method 204, test
condition C. After the test, switching rate, primary input power, transition time, VSWR, isolation, and insertion loss
4.7.10 Humidity (applicable to type E only) (see 3.6.10). Switches shall be tested in accordance with
MIL-STD-202, method 103, test condition A. After the test, switching rate, primary input power, transition time,
VSWR, isolation, and insertion loss shall be measured as specified in 4.7.2 through 4.7.6, respectively.
4.7.11 Hermetic seal (applicable to type H only) (see 3.6.11). Hermetically-sealed switches shall be tested in
accordance with method 112 of MIL-STD-202. The following details shall apply:
a.
Test condition letter: C (protective connector caps shall be used during test).
b.
Procedure III.
c.
Degree of leakage rate sensitivity: See 3.6.11.
4.7.12 Immersion (applicable to type I only) (see 3.6.12). Immersion-proof switches shall be tested in accordance
with method 104 of MIL-STD-202. The following details shall apply:
a.
Test condition letter: A (protective connector caps shall be used during test).
b.
During test cycle and while submerged, the sample shall be subjected to a low barometric pressure of
3.44 in Hg (50,000 feet altitude).
c.
Measurements: No leakage as evidenced by a continuous stream of bubbles. Bubbles which are the result
of entrapped air on the exterior surface of the switch shall not be considered as an indication of leakage.
After the test, switching rate, primary input power, transition time, VSWR, isolation, and insertion loss shall be
4.7.13 Salt Atmosphere (see 3.6.13). Switches shall be tested in accordance with MIL-STD-202, method 101, test
condition B. After the test, switching rate, primary input power, transition time, VSWR, isolation, and insertion loss
4.7.14 Shock (see 3.6.14). Switches shall be tested in accordance with MIL-STD-202, method 213, figure 213-2,
time duration 11 ms, 20 g's. After the test, switching rate, primary input power, transition time, VSWR, isolation, and
4.7.15 Temperature-altitude (see 3.6.15). Switches shall be tested individually for environmental effects of altitude
and temperature in accordance with (1) MIL-STD-202, method 105, test condition D and (2) MIL-STD-202,
method 107, test condition B, with environmental test chamber exposure times of 2 hours for step 1 and of 4 hours for
step 3. After each test, switching rate, primary input power, transition time, VSWR, isolation, and insertion loss shall
