Standard Specification for
Biaxially Oriented Polymeric Resin Film for Capacitors in
This standard is issued under the fixed designation D 3664; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of the last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (e) indicates an editorial change since the last revision or reapproval.
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.
1.2 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 9.3 and Table 1
1.3 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
