1/ Lot size is based on number of reels, spools, or coils.
4.4.6 Rejected lot. Failure to pass any of the tests and inspections shall constitute failure of the lot
and the lot shall be rejected. If an inspection lot is rejected, the lot may be reworked to correct the
defects or screen out the defective units, and the lot submitted for re-inspection. Such lots shall be
separated from new lots and shall be identified as re-inspected lots.
4.4.7 Noncompliance. If a sample fails to pass group B inspection (see 4.4.5), the contractor shall
notify the cognizant inspection activity of such failure and take corrective action on the materials,
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,
group B inspection shall be repeated on replacement articles. (This includes all tests and examinations,
or only the 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
inspection has shown that the corrective action was successful. In the event of failure after re-inspection,
information concerning the failure shall be provided to the cognizant inspection activity.
4.5 Methods of inspection.
4.5.1 Visual and dimensional examination. The cable shall be examined to verify that the
workmanship and the characteristics listed in table III are in accordance with the applicable requirements.
The examinations and measurements specified in table III shall be made on specimens not less than 2
feet in length and cut no closer than 5 feet from the end of the sample unit. The examinations and
measurements shall be performed as specified in table III.
4.5.2 Coating. The weight, uniformity, and adherence of zinc coating on steel strands shall be
measured as specified in the tests for weight of tin or zinc coating, uniformity of zinc coating (Preece
method; see 6.3), and adherence of zinc coating for classes 1, 2, and 3 wire of ASTM A641/A641M, with
the following modifications of the Preece method:
a. All specimens shall withstand at least one immersion.
b. Uniformity shall be measured on three specimens from each sample unit of strand and the time of
immersion shall be 15 +1, -0, seconds. The coating shall be uniform if all three specimens withstand the
same number of immersions ±1 before the end point of the measured time is reached.
4.5.3 Tubing. A specimen of finished cable shall be looped back and wound tightly on itself for five
close turns. The ends shall be securely taped and the specimen shall be placed in an air oven
