Testing in general must comply with Section 6 of NEMA WC 57 or Section 6 of NEMA WC 70/ICEA S-95-658 as applicable. Specific tests required for particular materials, components, and completed cables must be as specified in the sections of the above standards applicable to those materials, components, and cable types. Perform tests in accordance with the additional requirements specified below. In addition to the manufacturer's routine sample testing, each reel provided must have passed an insulation resistance test and a shield continuity test. No wire or cable may be shipped until after the manufacturer's test reports have been submitted and approved.

1.5.2 Flame Tests

All multiple-conductor and single-conductor cable assemblies must pass IEEE 1202 flame tests (formerly under IEEE 383) or UL 1685 flame tests.
