Anotácia

This specification covers a thermoplastic poly(vinyl chloride) insulation for wire and cable at the prescribed temperature. This insulation is recommended for use in power and control circuits at the specified thickness and voltage ratings and to dry locations. Tests are done on insulated wire or cable in this specification solely to determine the relevant property of the insulation material and not to test the conductor or completed cable. The insulation shall conform to the physical property requirements prescribed for the following: (1) tensile strength and elongation for unaged specimen and aged (using air oven test) tubular and buffed die-cut specimen, (2) heat shock, (3) heat distortion, (4) vertical flame test, (5) tensile strength and elongation for oil resistance test, and (6) cold bond test. Electrical tests shall be performed in the following order: ac voltage test, insulation resistance test, and dc voltage test. The insulation shall conform to the other electrical requirements such as accelerated water absorption (including permittivity and capacitance) and dielectric strength, and shall meet the prescribed thickness as well.
