Standard Test Methods for Nonrigid Vinyl Chloride Polymer Tubing Used for Electrical Insulation

Standard Details

1.1 These test methods cover the testing of general-purpose (Grade A), low-temperature (Grade B), and high-temperature (Grade C)2 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.

Note 1: 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 standard, except for temperature, which shall be expressed in degrees Celsius. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

1.3 The procedures appear in the following sections:

Procedure	Section	ASTM Reference Standard
Brittleness Temperature	37 – 39	D746
Corrosion Tests	68 – 79	D1000
Dielectric Breakdown Voltage at High Humidity	59 – 67	E104
Dielectric Breakdown Voltage	52 – 58	D149
Dimensional Tests	8 – 14	D374
Effect of Elevated Temperatures	19 – 30	D412
Flammability Test		D8355,
		Test Method A
Oil Resistance Test	29 – 36	D471
Penetration Test	40 – 45
Sampling	6
Strain Relief Test	62 – 67
Tension Test	16 – 18	D412
Test Conditions	7
Volume Resistivity	46 – 51	D257

1.4 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. For specific hazard statements, see Section 5.

1.5 For fire test caveats, see Test Methods D8355.

1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International StandardDetails, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
