Unless otherwise specified (see 6.2), an inspection lot shall consist of all wire of the same Part or Identifying Number (PIN), produced under essentially the same conditions on the same machin
31、e, that is presented for inspection and shipment at one time. 4.2.2 Unit of product.

37、f the tests and inspections constitutes failure of the lot and the lot shall be rejected. 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 a
38、nd shall be identified as re-inspected lots. 4.2.9 Non-compliance. If a sample fails to pass group B or C inspections (see 4.2.5 and 4.2.7), the contractor shall notify the cognizant inspection activity of such failure and take corrective action on the materials or processes, or both, as warranted,
39、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, group B or C inspection shall be repeated on the replacement articles. (This includes all tests and examinations, or only the
40、test that the original sample failed, at the option of the cognizant inspection activity). Group A inspection may be re-instituted; however, final acceptance and shipment shall be withheld until group B or C inspection has shown that the corrective was successful. In the event of failure after re-in
41、spection, information concerning the failure shall be provided to the cognizant inspection activity. 4.2.10 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
