4.6.2.1.1 Inspection sample. One sample shall be selected per each 5,000 feet of cable, or fraction thereof, not to
exceed the total of five samples per order. Samples shall be selected periodically through the life of the contract to
assure representative results.
4.6.2.1.2 Noncompliance. No failures shall be allowed in group C inspection. If a sample unit fails to pass group
C inspection, acceptance of the product shall be discontinued until corrective action, acceptable to the government,
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 that the original sample failed, at the option of the government).
Groups A and B inspection may be reinstituted; however, final acceptance shall be withheld until the group C
reinspection has shown that the corrective action was successful. In the event of failure after re- inspection,
information concerning the failure and the corrective action taken shall be furnished to the cognizant inspection
activity and the procuring activity.
4.7 Methods of inspection.
4.7.1 Visual and dimensional inspection. Cable shall be inspected to verify that the design, construction of
conductors, ground wires, insulated conductors, shielding, identification coding, grouping and cabling, jacket,
diameter tolerances, marking, and workmanship are in accordance with the applicable requirements. The inspections
shall be made on a specimen not less than 2 feet in length and cut no closer than 5 feet from the end of the sample.
4.7.2 Spark test. All insulated conductors shall be subjected to the spark test in accordance with method 6211 of
FED-STD-228 or method 900 of UL 1581 with the following exceptions:
a. It shall be performed on all insulated conductors prior to cabling or shielding.
b. For conductors larger than 6 AWG, an adaptation of method 6211, satisfactory to the Government inspector,
