1/ Only required for initial certification or when there is a change in material used in manufacturing.
2/ Only required for initial certification, when there is a change in materials used, or when the
manufacturing process changes.
3/ Only required for initial certification or when there is a change in materials used. A certificate of
compliance is required, stating materials are inert to fungus growth.
4.5.2.1.1 Sampling plan. On a 5-year basis starting from the date of qualification, the lot shall be
selected from the cable with largest number of conductors that is covered by a single specification sheet
and is in production.
4.5.2.1.2 Failures. If one or more specimens fail to pass group B inspection, the sample shall be
considered to have failed.
4.5.2.1.3 Disposition of sample units. Units of product from which a specimen has failed shall not be
delivered on the contract or order, even though the inspection lot submitted is accepted.
4.5.2.1.4 Noncompliance. If a sample fails to pass group B inspection, the manufacturer shall notify
the qualifying activity and the cognizant inspection activity of such failure and take corrective action on the
materials or processes, or both, as warranted, and on all units of product which can be corrected and
which were manufactured under essentially the same conditions with essentially the same materials,
processes, etc., and which are considered subject to the same failure. Acceptance and shipment of the
product shall be discontinued until corrective action acceptable to the qualifying activity has been taken.
After the corrective action has been taken, groups A and B inspections shall be repeated on additional
sample units (all inspections, or the inspection on which the original sample failed, at the option of the
qualifying activity). Group A (and group B, if applicable) inspection may be reinstituted; however, final
acceptance and shipment shall be withheld until the group B inspection has shown that the corrective
action was successful. In the event of failure after reinspection, information concerning the failure shall
be furnished to the cognizant inspection activity and the qualifying activity.
4.6 Methods of inspection.
4.6.1 Visual and mechanical inspection. The cable shall be inspected to verify that the design,
construction, physical characteristics and dimensions, color, weight, marking, and workmanship are in
accordance with the applicable requirements.
4.6.1.1 Cable weight. A specimen of cable 26.44±.02 inches (672 ±.51mm) long shall be cut and
weighed in grams to the nearest one percent of its weight. The weight of the specimen, after conversion
from grams to weight in pounds per 1,000 feet, shall meet the applicable requirement.
