1. Scope

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.

These test methods are similar but not identical to those in IEC 60684-2.

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:

This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. For specific hazard statements, see Section .

1.4 This is a fire-test-response standard. The test procedure described measures the resistance of the tubing to ignition or the spread of flame after ignition when tested under the specified conditions.

1.5 This standard is used to measure and describe the response of materials, products, or assemblies to heat and flame under controlled conditions, but does not by itself incorporate all factors required for fire hazard or fire risk assessment of the materials, products, or assemblies under actual fire conditions.

1.6 The effect of elevated temperature is indicated by the changes in ultimate elongation and weight caused by exposure of the tubing to elevated temperatures for a specified time under controlled conditions of air circulation.

2. Referenced Documents (purchase separately) The documents listed below are referenced within the subject standard but are not provided as part of the standard.
