MIL-DTL-55116D
3.7.6 Humidity. Mated and unmated connectors shall be subjected to the test in accordance with
4.9.6. Following the test, the connectors shall meet the electrical requirements of 3.5 and the air leakage
requirement of 3.6.2.
3.7.7 Water immersion. There shall be no evidence of leakage into the body of unmated connectors or
into the body or contact-face area of mated connectors when tested in accordance with 4.9.7.
3.8 Marking. Marking shall conform to MIL-STD-13231.
3.9 Identification of contacts. All contacts shall be identified by letters, either raised or depressed, on
the front and on the rear surface of each male and female insert. Lettering shall be as specified on the
individual specification sheets.
3.10 Workmanship. Connectors and accessories shall be processed in such a manner as to be
uniform in quality, and shall be free from burrs, crazing, cracks, voids, pimples, chips, blisters, pinholes,
sharp cutting edges, and other defects as listed in 4.10, that will adversely affect life, serviceability, or
appearance. The connectors shall comply with the requirements of 3.3, 3.4, 3.8, and 3.9.
3.11 Safety requirements.
3.11.1 Personnel hazards. MIL-PRF-28800 safety requirements are applicable. Verification of
compliance with this requirement shall be via visual inspection (see 4.11).
3.11.2 Edge rounding exposed. Exposed edges and corners shall be rounded sufficiently to minimize
laceration/puncture hazards. The design goal being a minimum radius of 0.04 inch (1 mm) for edges, and
0.5 inch (12.7 mm) minimum for corners.
3.12 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.
4. VERIFICATION
4.1 Classification of inspections. The inspections specified herein are classified as follows:
a. Qualification inspection (see 4.5).
b. Conformance inspection (see 4.6).
c. Materials inspection (see 4.3).
4.2 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 contractor. The establishment and maintenance of a calibration
system to control the accuracy of the measuring and test equipment shall be in accordance with
ISO 10012, or equivalent. This requirement also applies to automatic test equipment.
4.2.1 Automatic testing. The inspection for insulation resistance and dielectric withstanding voltage
may be performed by automatic means, except during qualification testing. Insulation resistance and
dielectric withstanding voltage may be performed simultaneously in less than one minute provided that
the current flow in the circuit is zero before automatically proceeding to the next step. In addition, the
automatic test equipment shall be manually reset when failure occurs.
