Standard Test Methods for Polymeric Films Used for Electrical Insulation
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 | 5 and 6 |
| Dielectric Breakdown Voltage Dielectric Strength | 20 to 25 |
| Extractables | 64 to 69 |
| Heat-Seal Strength | 58 to 63 |
| Permittivity and Dissipation Factor | 41 to 46 |
| Resistance Method for Measuring the Tendency | |
| Corrode Metals | 37 to 40 |
| Sampling | 4 |
| Shrinkage | 47 to 52 |
| Strain Relief | 12 to 19 |
| Surface Resistivity | 26 to 30 |
| Tensile Properties | 11 |
| Thickness | 7 to 10 |
| Volume Resistivity | 31 to 36 |
| Water Absorption | 52 to 57 |
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 a specific warning statement see 23.1.
Note 1 - These test methods are similar to IEC 60674-2.
