ASTM D3664-04

Standard Specification for Biaxially Oriented Polymeric Resin Film for Capacitors in Electrical Equipment

ABSTRACT
This specification covers two types and three grades of thin biaxially oriented polymeric resin film composed of polyethylene terephthalate (PET, Class A) or polypropylene (PP, Class B) for use in capacitors for electrical equipment. Type I has smooth surfaces, while Type II has at least one rough surface. Each of these types is further subdivided into the following grades: Grade 1, not pre-treated; Grade 2, one side pre-treated to facilitate the vacuum deposition of metal; and Grade 3, both side pre-treated. The physical, mechanical, and electrical requirements for which the polymer films shall be tested on for conformance are as follows: tensile strength and modulus, and break elongation; insulation resistance and conducting paths; permittivity, dissipation factor, and dielectric breakdown voltage; nominal thickness and width; density; melting point; shrinkage; tear and impact strength, and fold endurance; color or clarity; moisture absorption and permeability; oxygen index and permeability; resistance to corrosive agents; heat or solvent resistance, and hygroscopic coefficient of expansion; aqueous extract conductivity; and acidity. Thicknesses of the capacitor films shall be carried out by either the roll weight, ten-sheet stack, or gravimetric methods.
SCOPE
1.1 This specification covers thin biaxially oriented polymeric resin film for use in capacitors for electrical equipment. The material is biaxially oriented to improve the tensile properties in the machine (MD) and transverse (TD) directions.
The following safety hazards caveat pertains only to the test methods section of this specification.  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 specific warning statements see and footnote B.
1.2 The values stated in SI units are the standard. The values in parentheses are for information only.
Note 1—This standard resembles IEC 60674-3-2, Specification for plastic films for electrical use, in title only. The content is significantly different.
