Standard Specification for Unsintered Polytetrafluoroethylene (PTFE) Extruded Film or Tape

SCOPE
1.1 This specification covers unsintered extruded films or tapes manufactured from virgin polytetrafluoroethylene, in nominal thickness from 0.025 to 0.39 mm (0.001 to 0.010 in.), and are > 97 % PTFE in composition.
1.1.1 The use of recycled PTFE for production of unsintered extruded films or tapes has not been identified at this time. When commercial usable processes and materials are available, this specification will be revised to include recycled materials.
1.2 The values stated in SI units are detailed in IEEE/ASTM SI 10 are to be regarded as the standard. The values given in parentheses are for information only.
1.3 The following precautionary statement pertains only to the test method portion, Section 8 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.
Note 1--There is no ISO standard that covers information included in this specification. A few of the test methods are mentioned in ISO 12086-2: 1995.
