3、ober 2007.1. Scope1.1 This specification covers a thermoplastic insulation ofpoly(vinyl chloride) or the copolymer of vinyl chloride andvinyl acetate.1.2 This insulation is recommended for use at conductortemperatures not in excess of 60 C in wet or dry locations ata maximum voltage rating of 600 V

4、for power and controlcircuits.1.3 Whenever two sets of values are presented, in differentunits, the values in the first set are standard, while those inparentheses are for information only.1.4 In many instances the insulation material cannot betested unless it has been formed around a conductor or c

5、able.Therefore, tests are done on insulated wire or cable in thisspecification solely to determine the relevant property of theinsulation material and not to test the conductor or completedcable.2.
