4.6 Conformance inspection. Conformance inspection shall consist of the inspections listed for groups A, B,
and C. Conformance inspection shall be performed on every lot of cable procured under this specification.
4.6.1 Inspection lot. An inspection lot shall consist of all cables of any one type produced under substantially
the same conditions and offered for inspection at one time.
4.6.1.1 Lot rejection. In the event that failure is incurred in the samples as specified herein, the lot represented
by the samples shall be rejected. The contractor may screen out defectives or rework the lot and submit it
again for conformance.
4.6.2 Group A inspection. Group A inspection shall consist of the examination and tests provided in table VII.
One sample from each 10,000 feet of cable shall be inspected for the visual and dimensional requirements and
conductor resistance. The voltage test for insulated conductors shall be conducted on each reel prior to
cabling. The voltage test and insulation resistance test on completed cable shall be performed on the entire lot
of finished cable submitted in accordance with 4.6.1.
