ASTM D 876:2021

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 Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
