MIL-DTL62062E
After the examination, the blower shall be reassembled and subjected to testing as specified in
4.4.4.2.
4.4.5 Interface requirements verification.
4.4.5.1 Electromagnetic compatibility. To determine conformance to 3.4.1, the blower
shall be tested and pass the test in accordance with MIL-STD-461.
4.4.5.2 Painting. To determine conformance to 3.4.2, the finish applied to the blower
assembly shall be visually inspected for conformance to this specification.
4.4.5.3 Interchangeability. To determine conformance to 3.4.3, the interchangeability
between different parts and assemblies having the same military part number shall be
demonstrated using one or more of the methods outlined in 4.4 or 4.4.1.
4.4.6 Support and ownership requirements verification.
4.4.6.1 Identification marking. To determine conformance to 3.5.1, the presence of the
identification marking required in this specification shall be visually inspected (see table IV).
4.4.6.2 Safety. To determine conformance to 3.5.2, the blower shall be visually
inspected for hazardous burrs, sharp edges, foreign materials, or other imperfections that pose
physical danger to an installer/operator. The assembly shall be inspected for exposed, frayed,
unsecured, or otherwise improperly protected circuits that pose electrical danger to the
installer/operator.
4.4.7 Operating environment requirements verification.
4.4.7.1 High temperature. To determine conformance to 3.6.1, the blower shall be stored
in a test chamber at 71 + 3C for a period of 24 hours. The blower shall then be operated for a
period of 4 hours at the 71 + 3C temperature. During operation the voltage input to the blower
shall be between 27 and 29 V with the input to the blower at not more than 14.5 A.
4.4.7.2 Low temperature. To determine conformance to 3.6.2, the blower shall be stored
in a test chamber at -18 + 3C for a period of 24 hours. The blower shall then be operated for a
period of 4 hours at the -18 + 3C temperature. During operation the voltage input to the blower
shall be between 27 and 29 V with the input to the blower at not more than 14.5 A.
4.4.7.3 Vibration. To determine conformance to 3.6.3, the blower shall be mounted
rigidly along any of the principal axes using a mounting apparatus which is free from resonances
over the test frequency range. The blower shall be subjected to a simple harmonic motion
having an amplitude of 0.03 inch (0.06-inch maximum total excursion), the frequency being
varied uniformly between the approximate limits of 10 and 55 Hz. The entire frequency range,
from 10 to 55 Hz and return to 10 Hz, shall be traversed in approximately 1 minute. This motion
shall be applied for a period of 24 hours in each of 3 mutually perpendicular directions (total 72
