1.1 These test methods cover the testing of heat-shrinkable tubing used for electrical insulation. Materials used include poly(vinyl chloride), polyolefins, fluorocarbon polymers, silicone rubber, and other plastic or elastomeric compounds. 1.2 The procedures appear in the following sections: Procedure Sections ASTM Method Reference Adhesive Peel Strength 98 - 104 Brittleness Temperature 40 D746 Color 55 and 56 D1535 Color Stability 57 - 62 D1535 Conditioning 7 D618 Copper Stability 93 Coro sion Testing 89 - 95 Dielectric Breakdown 20 - 25 D149 Dimensions 8 - 13 D876 Flammability 68 - 72 D876 Fluid Resistance 63 - 67 Fungus Resistance 104 - 108 Heat Resistance 49 - 54 Heat Shock 26 - 30 Low-Temperature Properties 36 - 43 Restricted Shrinkage 14 - 19 Selection of Test Specimens 6 Secant Modulus 81 - 84 D882 Storage Life 31 - 35 Specific Gravity 73 and 74 D792 Stress Modulus 85 - 88 D412 Tensile Strength and Ultimate Elongation 44 - 48 D412 Thermal Endurance 96 and 97 Volume Resistivity 75 - 78 D257 Water Absorption 79 and 80 D570 Melting Point 104 - 108 D3418 1.3 This is a fire-test-response standard. 1.4 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. 1.5 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 Sections 5 and 68.2. Note 1 - These test methods are similar, but not identical to, those in IEC 60684-2 (see also Note 9).
