MIL-PRF-22885H
4.6.3.1.4 Noncompliance. If a sample fails to pass group B inspection, the contractor shall notify the qualifying
activity and the cognizant inspection activity of such failure and 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, and so forth, and which are
considered subject to the same failure. Acceptance of the product shall be discontinued until corrective action,
acceptable to the Government, has been taken. After the corrective action has been taken, group B inspection shall
be repeated on additional sample units (complete inspection, or the inspection which the original sample failed, at the
option of the Government.) Group A inspection may be reinstituted; however, final acceptance shall be withheld until
the group B reinspection has shown that the corrective action was successful. In the event of failure after
reinspection, information concerning the failure and the corrective action taken shall be furnished to the contracting
officer and the qualifying activity.
4.7 Methods of inspection.
4.7.1 Visual and mechanical inspection. Switches and associated modular sub-assemblies shall be examined to
verify that the materials, physical dimensions, marking, and workmanship are in accordance with the applicable
4.7.1.1 Switching characteristic. The switching operation shall be examined by use of suitable test circuits for
4.7.1.2 Lamp circuit. The lamp circuit shall be examined for continuity and operation for compliance with the
4.7.2 Solderability (applicable to solderable terminals, see 3.7). Switches shall be tested in accordance with
method 208 of MIL-STD-202. The soldering iron method may be used. The following details and exceptions shall
apply:
a.
Number of terminals to be tested: A minimum of two switch and two lamp terminals shall be tested. When
lamp terminals are located only on recessed planes and cannot be readily dipped, separate specimens of
the lamp terminals may be tested.
b.
Examination of terminals: Method for evaluation of lugs and tabs shall apply.
4.7.3 Resistance to soldering heat (applicable to switches with solderable terminals, see 3.8). Switches shall be
tested in accordance with method 210 of MIL-STD-202. The following details shall apply:
a.
Number of terminals to be tested: A minimum of two terminals of closed contacts per switch and two
indicator light terminals (the indicator light terminals may be tested separately).
b.
Depth of immersion in molten solder: Terminals shall be immersed to within .079 inch to .099 inch (2.0 mm
to 2.5 mm) of the switch body.
c.
Test condition letter: B.
d.
Cooling time prior to final examinations and measurements: Not applicable.
e.
Examinations and measurements:
(1)
Before: None.
(2)
After: Internal examination not required. Samples shall be subjected to Group IV testing in the
qualification table.
