4.5.3.1 Failure. Failure of any specimen to pass any inspection listed in table IX shall be cause for
re-inspection of twice the original number of specimens selected for the test failed. These specimens
shall be selected from the unit of product from which the 20 foot (6.1 meters) length of cable that failed
had been originally taken. Failure of any specimen during re-inspection shall be cause for rejection of the
lot.
4.6 Control tests. Unless otherwise specified (see 6.2), control tests shall be conducted on 6 feet
(1.83 m) of cable from each 10,000 feet (305,000 m) of cable produced, except that no more than two
lengths of 6 feet (1.83 m) each shall be selected in any 30-day period. The cable shall be subjected to
the control tests specified in table V.
4.6.1 Failure. Failure of a control test sample to pass the specified test shall be cause for the
Government to refuse to accept subsequent lots until it has been proved to the satisfaction of the
Government that corrective action on the materials or process, or both, as warranted, has been taken and
is successful.
4.7 Methods of inspection.
4.7.1 Materials and construction. Conformance to materials, design, and construction shall be
determined by inspection of contractor records providing proof or certification that design, construction,
processing, and materials conform to requirements. Applicable records include drawings, specifications,
design data, receiving inspection records, processing and quality control standards, vendor catalogs and
certifications, industry standards, test reports, and rating data.
4.7.1.1 Copper strands. The sample shall be tested as specified in A-A-59551.
4.7.1.1.1 Tin coating. The sample shall be tested as specified in ASTM-B33.
4.7.1.1.2 Nickel coating. The sample shall be as specified in ASTM-B355.
4.7.1.1.2.1 Adhesion of nickel coating. Two 6-inch specimens shall be cut from the sample of nickel
coating strand. One specimen shall be wrapped over its own diameter for eight close turns. The second
specimen shall remain in its straight form. Both specimens shall then be subjected to 10 continuous
cycles of temperature change consisting of 4 hours at 482±5.4 °F followed by 4 hours at room
temperature. Upon completion of the thermal cycling, the straight specimen shall be wrapped over its
own diameter for eight close turns in a manner identical to that of the first specimen. Both wrapped
specimens shall then be tested for continuity of coating in accordance with the procedure as specified in
4.7.2 Examination. The sample shall be examined for the conditions listed in table VIII.
