4.2.2 Conformance inspection. Conformance inspections shall be those tests specified in table XI

and shall be performed on specimens taken from the finished cable or material removed from finished

cable of each lot of reels, spools, or coils to be delivered. Sampling inspection shall be accomplished for

each lot specified in 4.2.2.2.

4.2.2.1 Lot. A lot shall consist of all cable of one type manufactured substantially under the same

conditions and offered for inspection at one time.

4.2.2.2 Sampling . A random sample shall be selected from each lot specified in table XII.

4.2.2.3 Rejected lots. Failure of any sample to pass any inspection shall constitute a failure of the

lot. If an inspection lot is rejected, the contractor may rework the lot to correct the defects, or screen out

the defective units and resubmit the lot for re-inspection. Such lots shall be separated from new lots and

shall be identified as re-inspected lots (see 4.2.2.4).

4.2.2.4 Noncompliance. If a sample fails to pass any inspection, the contractor shall notify the

cognizant inspection activity of such failure and take corrective action on the materials or processes, or

both, as warranted on all units of the product. Acceptance and shipment of the product shall be

discontinued until corrective action has been taken. After the corrective action has been taken, the

conformance inspection shall be repeated on replacement articles. This includes all tests and

examinations, or only the test that the original sample failed at the cognizant inspection activity. Final

acceptance and shipment will be withheld until inspection has shown that the corrective action was

successful. In the event of failure after re-inspection, information concerning the failure should be

provided to the cognizant inspection activity.
