1.1 These test methods cover the testing of general-purpose (Grade A), low-temperature (Grade B), and high-temperature (Grade C) nonrigid vinyl chloride polymer tubing, or its copolymers with other materials, for use as electrical insulation. For the purpose of these test methods nonrigid tubing shall be tubing having an initial elongation in excess of 100% at break.
1.2 The values stated in inch-pound units are to be regarded as the standard, except temperature, which shall be stated in degrees Celsius. Values in parentheses are for information only.
1.3 The procedures appear in the following sections:
