Standard Test Methods for Heat-Shrinkable Tubing for Electrical Use

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 values stated in inch-pound units are the standard except for temperature, which shall be expressed in degrees Celsius. Values stated in parentheses are for information only.

1.3 The procedures appear in the following sections:

ASTM Method Procedure Sections Reference Adhesive Peel Strength 98 to 104 Brittleness Temperature 40 D 746 Color 55 to 56 D 1535 Color Stability 57 to 62 D 1535 Conditioning 7 D 618 Copper Stability 93 Corrosion Testing 89 to 95 Dielectric Breakdown 20 to 25 D 149 Dimensions 8 to 13 D 876 Flammability 68 to 72 D 876 Fluid Resistance 63 to 67 Heat Resistance 49 to 54 Heat Shock 26 to 30 Low-Temperature Properties 36 to 43 Restricted Shrinkage 14 to 19 Selection of Test Specimens 6 Secant Modulus 81 to 84 D 882 Storage Life 31 to 35 Specific Gravity 73 to 74 D 792 Stress Modulus 85 to 88 D 412 Tensile Strength and Ultimate Elongation 44 to 48 D 412 Thermal Endurance 96 to 97 Volume Resistivity 75 to 78 D 257 Water Absorption 79 to 80 D 570

1.4 This is a fire-test-response 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.
