These test methods detail the standard procedures for testing hookup wire insulations including all components of the insulation system used on single insulated conductors or an assembly of single insulated conductors such as a cable bundle and harness or flat ribbon cable. The insulating materials include not only the primary insulation over the conductor, but also insulating jackets over shielded constructions. The test procedures covered here shall be performed in the conditions or shall determine the properties, as follows: axial stability (longitudinal change) after thermal exposure; bondability to potting compounds; capacitance; cold bend test; concentricity; crush resistance; dielectric breakdown voltage; dimensions; dry-arc tracking; dynamic cut-through; fluid immersion; high temperature shock; insulation-continuity proof tests; insulation resistance; partial discharge (corona) inception and extinction voltage; relative thermal life and temperature index; strip force; surface resistance; tensile properties; vertical flame test; voltage rating of hook-up wire; voltage withstand test; and wet arc-tracking.
