1.1 These test methods cover the testing of homogeneous organic polymer films not over 2.4 mm (95 mils) thick that are to be used for electrical insulation. 1.2 These test methods are not necessarily applicable to testing films in combinations with a coating, another film, or with other types of substrate, such as fabrics or papers. 1.3 The values stated in SI units are the standard. The values in parentheses are provided for information only. 1.4 The procedures appear in the following sections: Procedure Sections Conditioning  6 and 7 Dielectric Breakdown Voltage & Dielectric Strength 21 to 26 Extractables 65 to 70 Heat-Seal Strength 59 to 64 Permittivity and Dissipation Factor 42 to 47 Resistance Method for Measuring the Tendency to    Corrode Metals 38 to 41 Sampling 5 Shrinkage 48 to 53 Strain Relief 13 to 20 Surface Resistivity 27 to 31 Tensile Properties 12 Thickness  8 to 11 Volume Resistivity 32 to 37 Water Absorption 53 to 58 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. Note 1: These test methods are similar to IEC 60674–2. 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.
