This specification covers unfilled, unpigmented FEP-fluorocarbon resin sheet and film. The sheet and film shall be made from FEP-fluorocarbon resin without filler or plasticizer. This specification allows for the use of recycled, reprocessed, and reworked FEP materials provided that: the final physical, mechanical, and performance requirements are met; and the toxicological characteristics are essentially unaltered from that of virgin material. The tensile strength, elongation at break, dimensional change on heating, cementability, dielectric strength, and density of the sheet and film shall be tested.

1.1 This specification covers unfilled, unpigmented FEP-fluorocarbon resin sheet and film less than 3.175 mm (0.125 in.) thick. Recycled materials are allowed in accordance with 6.2.

1.2 The values stated in SI units as detailed in are to be regarded as standard and the practices of incorporated herein.

1.3 The following safety hazards caveat pertains only to the test methods portion, Section 14, 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 known ISO equivalent to this standard.
