Active Standard ASTM D7193 | Developed by Subcommittee: D20.15
Book of Standards Volume: 08.03
Historical (view previous versions of standard)
1.1 This specification covers unsintered, pigmented, extruded films or tapes manufactured from polytetrafluoroethylene, in nominal thicknesses from 0.025 mm (0.001 in.) to 0.51 mm (0.020 in.), which are >97 % virgin PTFE in composition prior to introducing pigments.
Note 1—For unsintered non-pigmented products refer to Specification D6585.
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.
1.3 This standard does not purport to address all of the safety problems 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 2—Although this specification and ISO/DIS 13000-1 (1997) and ISO/DIS 13000-2 (1997) differ in approach or detail, data obtained relating to specific properties, using either are technically equivalent.
Note 3—This specification is intended to be a complement to Specification D6585, as the materials covered herein vary significantly enough due to their additives to warrant a stand-alone set of requirements.
