MIL-DTL-55041F
4.7.24 Explosion (see 3.26). The switch shall be tested in accordance with test method 109 of MIL-STD-202.
Indicator and interlock circuits shall be energized at rated voltage and current (see 3.1). Unless otherwise specified
(see 3.1), switches that are pressurized and are designed so that the switching mechanism is completely isolated
from the RF path need not have RF power applied. However, all other switches shall be tested with full RF power
applied.
4.7.25 Salt atmosphere (see 3.27). The switch shall be tested in accordance with test condition B of method 101,
MIL-STD-202. The waveguide ports shall be sealed during this test.
4.7.26 Sand and dust (see 3.28). The switch shall be tested in accordance with step 1 only of test method 110,
MIL-STD-202. The air velocity shall be between 100 and 500 feet per minute. Unless otherwise specified (see 3.1),
protective caps shall be used to cover the waveguide ports.
4.7.27 Post electrical tests, environmental. Following environmental tests, pull-in and dropout voltages, operating
and holding currents, rotor motion delay (when specified), dielectric withstanding voltage, isolation, VSWR, insertion
loss and switching time shall be measured as specified in 4.7.4 through 4.7.9 and 4.7.11 through 4.7.14, respectively.
5. PACKAGING
5.1 Packaging. For acquisition purposes, the packaging requirements shall be as specified in the contract or order
(see 6.2). When packaging of materiel is to be performed by DoD or in-house contractor personnel, these personnel
need to contact the responsible packaging activity to ascertain packaging requirements. Packaging requirements are
maintained by the Inventory Control Point's packaging activities within the Military Service or Defense Agency, or
within the military service's system commands. Packaging date retrieval is available from the managing Military
Department's or Defense Agency's automated packaging files, CD-ROM products, or by contacting the responsible
packaging activity.
6. NOTES
