Visual and mechanical examination
4.5.1.1.6 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 condition, 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 which 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 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 taken 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 shall be examined to verify that the materials,
design, construction, marking and workmanship are in accordance with the applicable requirements
(see 3.1, 3.4, 3.5, and 3.27).
4.6.2 Torque to couple/uncouple (see 3.6). While applying a coupling or an uncoupling force to the
coupling ring at a uniform rate of approximately 4 inch-pound per second, the torque required to mate and
unmate the plug from its counterpart shall be measured and recorded.
