found at any inspected end, the other end of that length shall be examined for the same defect. The reel
that contains the adjacent section of cable shall also be examined for the same defect.
4.5.2.2 Sampling for insulation and continuity tests. In each shipping length of cable, tests shall be
performed on the number of pairs specified in 4.5.2.1. Each of the selected pairs shall be subjected to all
of the tests necessary to verify conformance to 3.2.2, 3.2.2.1 and 3.3.3, respectively. If any pair fails in
any test, the entire length of cable shall not be offered for delivery. The same pair on the adjacent reels
shall be subjected to the same test in which the failure occurred.
