Scope of standard 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''These test methods appear in the following sections: Procedure Section(s) Test Method(s) Adhesive Peel Strength 94 ''' 100 '' Brittleness Temperature 40 D746 Color 55 and 56 D1535 Color Stability 57 ''' 62 D1535 Conditioning 7 D618 Copper Stability 89 '' Corrosion Testing 85 ''' 91 '' Dielectric Breakdown 20 ''' 25 D149 Dimensions 8 ''' 13 D876 Flammability 68 D8355 (Methods A, C, or D) Fluid Resistance 63 ''' 67 '' Fungus Resistance 100 ''' 104 '' Heat Resistance 49 ''' 54 '' Heat Shock 26 ''' 30 '' Low-temperature Properties 36 ''' 43 '' Restricted Shrinkage 14 ''' 19 '' Selection of Test Specimens 6 '' Secant Modulus 77 ''' 80 D882 Storage Life 31 ''' 35 '' Specific Gravity 69 and 70 D792 Stress Modulus 81 ''' 84 D412 Tensile Strength and Ultimate Elongation 44 ''' 48 D412 Thermal Endurance 92 and 93 '' Volume Resistivity 71 ''' 74 D257 Water Absorption 75 and 76 D570 Melting Point 100 ''' 104 D3418 1.3''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. 1.4''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 and for fire test safety caveats see Test Methods D8355. Note 1:''These test methods are similar, but not identical to, those in IEC 60684-2 (see also Note 9). 1.5''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.
