MIL-DTL-83522E
completion of the test in order to meet the requirements of 3.5.1.2. At the completion of the test, the connector shall be visually
examined with 4.7.2.
4.7.16 Impact (see 3.5.2.6). Unmated connector plugs with protective covers (i.e., dust cap over ferrules) installed shall be tested
in accordance with the following or other suitable technique:
a. The impact test facility shall consist of a clamp for securing a single jumper cable and a steel block, 1/2 inch (1.2 cm)
minimum thickness, as shown on figure I.
b. The impact test shall be conducted as follows: The cable is clamped so that, with the connector plug hanging under its own
weight, the end of the plug extends 59 inches (1.5 meters) below the cable clamp to the center of the steel block. The plug is
then raised to the height of the clamp, and with the cable extended, released so as to strike the block. The unmated plug shall
be dropped 8 times.
c. The change in optical transmittance shall be measured after the test (see 3.5.1.2).
d. At the completion of the test, the connector shall be visually examined in accordance with 4.7.2.
4.8 Environmental requirements. The environmental tests in 4.8.2 through 4.8.16 shall be performed per the applicable TIA-455
series standards with the exception for adhering strictly to the setup and test procedure specified in the applicable 3200, 3300 and 3400
series measurements in MIL-STD-1678-3. Connectors with a composite body shall be unmated and re-mated after each environmental
test. Post exposure optical transmittance measurements may be taken up to 24 hours after completion fo the environmental exposure.
4.8.1 Pressure altitude (see 3.5.3.1). Connector mated pairs shall be tested for susceptibility to low pressure (altitude) in
accordance with method 500 of MIL-STD-810. The following conditions shall apply:
a. Specimens shall be mounted in a manner simulating that in actual service.
b. Pressure shall be increased or decreased, as applicable, at a rate not to exceed 2,500 feet per minute.
c. Operating and non-operating: Specimens shall be subjected to a simulated altitude of 70,000 feet above sea level for a
minimum of 2 hours. Change in optical transmittance measurements shall be performed at 15 minute intervals during and
immediately following the test and there shall be no degradation of optical performance beyond the limits specified in 3.5.1.2.
Following the test, specimens shall be examined for compliance to 3.5.3.1.
d. At the completion of the test, the connector shall be visually examined in accordance with 4.7.2.
