MIL-DTL-55041F
3.22 Moisture resistance. When electromechanically operated switches are tested as specified in 4.7.20, the
switch shall be capable of reliable operation. Following the test, the switch shall be capable of meeting the specified
isolation, VSWR, insertion loss, holding current, pull-in voltage, dropout voltage, switching time and rotor motion
delay requirement.
3.23 Pressure (when specified) (see 3.1). When pressurized switches are tested as specified in 4.7.21 at the
specified pressure (see 3.1), the leak rate of the switches shall be less than 5.0 standard atmosphere cubic
centimeter per minute or shall be such that no stream of bubbles emanates from the switches.
3.24 Vibration. When tested as specified in 4.7.22, there shall be no evidence of displacement or loosening of
parts. Following this test, the switch shall be capable of meeting the specified isolation, VSWR, insertion loss,
holding current, pull-in voltage, dropout voltage, switching time, and rotor motion delay requirements.
3.25 Shock (specified pulse). When tested as specified in 4.7.23, the switches shall show no evidence of damage
or loosening of parts. Following this test, the switch shall be capable of meeting the specified isolation, insertion loss,
and switching time requirements.
3.26 Explosion (when specified) (see 3.1). When switches are tested as specified in 4.7.24, there shall be no
explosion within the test chamber. Following this test, the switch shall be capable of meeting the switching time
requirement.
3.27 Salt atmosphere (when specified) (see 3.1). When tested as specified in 4.7.25, the surfaces of the switch
shall exhibit no marked pitting or corrosion. Following this test, the switch shall be capable of meeting the switching
time, insertion loss, and dielectric withstanding voltage requirements.
3.28 Sand and dust. When electromechanically operated switches are tested as specified in 4.7.26, there shall be
no evidence of sand and dust accumulation within the enclosure.
3.29 Post electrical tests, environmental (see 4.7.27). Following the environmental tests, pull-in and dropout
voltages, operating and holding currents, rotor motion delay, dielectric withstanding voltage, isolation, VSWR,
insertion loss and switching time shall meet the specified values.
3.30 Marking. Switches shall be marked in accordance with MIL-STD-1285 with PIN (see 1.2) and manufacturer's
source code. The marking shall remain legible after completing all environmental tests specified herein.
a.
Electromechanically operated switches shall be marked with the type of supply, the operating voltage,
and the frequency in the case of an ac supply.
b.
Waveguide ports shall be marked in a logical manner to identify the input and output ports.
3.31 Recycled, recovered, or environmentally preferable materials. Recycled, recovered, or environmentally
preferable materials should be used to the maximum extent possible, provided that the material meets or exceeds the
operational and maintenance requirements, and promotes economically advantageous life cycle costs.
3.32 Workmanship. Switches shall be manufactured and processed in such a manner as to be uniform in quality,
and the surfaces of the switch shall be free from tool marks, burrs, deep scratches, and other defects that will affect
life, serviceability, or appearance.
4. VERIFICATION
4.1 Test equipment and inspection facilities. Test and measuring equipment and inspection facilities of sufficient
accuracy, quality and quantity to permit performance of the required inspection shall be established and maintained
by the manufacturer. The establishment and maintenance of a calibration system to control the accuracy of the
measuring and test equipment shall be in accordance with NCSL-Z540.3.
