ASTM D2219 Standard Specification for Poly(Vinyl Chloride) Insulation for Wire and Cable, 60°C Operation
ASTM D2219 电线和电缆用聚氯乙烯绝缘材料(工作温度60℃)的标准规范

This specification covers thermoplastic insulating materials made of poly(vinyl chloride) or the copolymer of vinyl chloride and vinyl acetate recommended for use in wires and cables operating in wet or dry locations at specified conductor temperatures and maximum voltage ratings for power and control circuits. Since the insulation material cannot be tested unless it has been formed around a conductor or cable, tests shall then be done on insulated wire or cable solely to determine the relevant property of the insulation material and not to test the conductor or completed cable. Materials shall conform to the following physical requirements: unaged tensile strength and elongation at rupture; tensile strength and elongation after air oven aging; heat shock; heat distortion; behavior during vertical flame test; oil resistance; tensile strength and elongation after oil immersion; behavior during cold bend test, and size and thickness. Insulations shall also perform satisfactorily during tests for AC and DC voltage, insulation resistance, accelerated water absorption, and dielectric strength retention.
This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.

1. Scope
1.1 This specification covers a thermoplastic insulation of poly(vinyl chloride) or the copolymer of vinyl chloride and vinyl acetate.
1.2 This insulation is recommended for use at conductor temperatures not in excess of 60°C in wet or dry locations at a maximum voltage rating of 600 V for power and control circuits.
1.3 In many instances, the insulation material cannot be tested unless it has been formed around a conductor or cable. Therefore, 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.
1.4 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
1.4.1 In some cases (including the title), temperatures are described in degrees Celsius only.
