MIL-DTL-22992G
4.5.4.2 Noncompliance. If a sample fails to pass group C inspection, the supplier shall take
corrective action on the materials or processes, or both, as warranted, and on all units of product which
can be corrected and which were manufactured under essentially the same conditions, with essentially
the same materials, processes, etc, and which are considered subject to the same failure. Acceptance of
the product shall be discontinued until corrective action, acceptable to the qualifying activity, has been
taken. After the corrective action has been taken, group C inspection shall be repeated on additional
sample units (all inspections, or the inspection that the original sample failed, at the option of the
qualifying activity). Groups A and B inspections may be reinstituted, however, final acceptance shall be
withheld until the group C reinspection has shown that the corrective action was successful. In the event
of failure after reinspection, information concerning the failure and corrective action shall be furnished to
the cognizant inspection activity and the qualifying activity.
4.6 Methods of examination and test.
4.6.1 Visual and mechanical examination. Connectors, adapters, protective covers and stowage
receptacles shall be examined to verify that the material, design, construction, physical dimensions,
4.6.2 Magnetic permeability. Permeability of the connectors shall be measured with an instrument
conforming to ASTM A342/A342M (see 3.5).
4.6.3 Shell-to-contact resistance (class L grounding). The electrical resistance between grounding
contacts and the shell shall be determined by measuring the potential drop from each grounding contact
to the shell when carrying a current of 1 ± 0.1 amperes dc. Using the voltmeter-ammeter method, the
potential drop shall be measured at the extreme terminal end of the grounding pin or socket and the front
of the shell (plug or receptacle) (see 3.6).
4.6.4 Contact resistance. Each pair of mated pin and socket contacts shall be tested after only one
mating of the contacts, in accordance with test procedure of EIA-364-06 (see 3.7). The following details
and exceptions shall apply:
a. Wire size and type - See 4.4.3.
b. Test current - See table I.
c.
Test sample preparation - In addition to the preparation in test procedure 06, the
unassembled contacts shall be mated to the minimum depth as determined when the
contacts are installed in the appropriate connectors. The potential drop shall be
measured at the extreme terminal ends of the contacts. See figure 2 for wiring diagram.
d. Millivolt drop requirements - See table I.
