6.1 Physical tests, properly interpreted, provide information with regard to the physical properties of the insulation or jacket. The physical test values give an approximation of how the insulation will physically perform in its service life. Physical tests provide useful data for research and development, engineering design, quality control, and acceptance or rejection under specifications.1.1 These test methods cover procedures for the testing of thermoplastic insulations and jackets used on insulated wire and cable. To determine the test to be made on the particular insulation or jacket compound, refer to the product specification for that type. These test methods do not apply to the class of products known as flexible cords. The electrical tests on insulation and water-absorption tests do not apply to the class of products having a separator between the conductor and the insulation.1.2 These test methods pertain to insulation or jacket material for electrical wires and cables. In many instances the insulation or jacket material cannot be tested unless it has been formed around a conductor or cable. Therefore, tests are done on insulated or jacketed wire or cable in these test methods solely to determine the relevant property of the insulation or jacket material and not to test the conductor or completed cable.1.3 Whenever two sets of values are stated, in different units, the values in the first set are regarded as standard, while the values in parentheses are provided for information only and are not considered standard.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 hazards see Section 4 and for fire test safety caveats see Test Method D8354.1.5 These test methods appear in the following sections:Test Method Section(s)   Cold Bend Test 75 to 77Dielectric Strength Retention Test 45 to 51Electrical Tests of Insulation 17 to 29Heat Distortion Test 74Heat Shock Test 73Insulation Resistance Test 30 to 37Test Method Section(s)   Partial-discharge Extinction Level Test 38 to 44Physical Tests of Insulation and Jackets 5 to 16Flammability 63(Test Method D8354)Surface Resistivity Test 64 to 67Thermal Tests 72 to 77Track Resistance Test 78 to 81U-bend Discharge Test 68 to 71Vertical Flame Test 63Water Absorption Tests, Accelerated 52 to 621.6 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.

This specification covers poly(vinyl chloride) thermoplastic insulation for conducting wires and cables operating continuously at a specified conductor temperature, within the specified voltage range, and under wet or dry conditions. The insulation has potential low-temperature installation limitations. The prescribed tests cannot be performed unless the insulation is formed around a conductor, but these are done solely to determine the insulation properties and not to test the conductor or completed cable. Each test sample should be subjected to an ac and dc voltage withstand tests and insulation resistance test and should comply with the required values for unaged and aged requirements of tensile strength and elongation at rupture, heat shock, heat distortion, vertical flame test results, oil resistance, and cold bend test results. All joints and repairs in the insulation should be done in such a way as the affected parts meet the same electrical requirements as the rest of the insulation.1.1 This specification covers a thermoplastic insulation of poly (vinyl chloride) or the copolymer of vinyl chloride and vinyl acetate. This insulation is recommended for use at conductor temperatures not in excess of 90 °C.1.2 Depending on the thickness of the insulation, the maximum voltage used, and whether the location is wet or dry, this insulation is acceptable for use in 300 V (dry) and 600 V (wet or dry) power and control circuits.1.3 This insulation has potential low-temperature installation limitations. Consult the manufacturer for specific recommendations for installation.1.4 In many instances, the insulation material cannot be tested unless it has been formed around a conductor or cable. Therefore, tests are done on insulated wire or cable in this specification solely to determine the relevant property of the insulation material and not to test the conductor or completed cable.1.5 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.1.5.1 In some cases (including the title), temperatures are described in degrees Celsius only.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.

For copper conductors, the insulation can be applied over the uncoated metal.1.3 Materials covered by this specification are not sunlight and weather resistant unless they are carbon black pigmented or contain an additive system designed for this protection.1.4 In many instances the insulation cannot be tested unless it has been formed around a conductor. Therefore, tests are done on insulated wire in this standard solely to determine the relevant property of the insulation and not to test the conductor or completed cable.1.5 Whenever two sets of values are presented, in different units, the values in the first set are the standard, while those in parentheses are for information only.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.
