Significance and Use

Many electrical and physical properties of films vary significantly with changes in temperature and humidity. Properties of thin plastic films can change very rapidly; therefore, the specimen should be in the stated conditioning environment when the test is being performed. When the test is performed in a different environment, note these conditions and the time of exposure to this new environment.


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:

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 Metals37 to 40
Sampling 4
Shrinkage 47 to 52
Strain Relief 12 to 19
Surface Resistivity 26 to 30
Tensile Properties11
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.
