1、Designation: D 6585 05Standard Specification forUnsintered Polytetrafluoroethylene (PTFE) Extruded Film orTape1This standard is issued under the fixed designation D 6585; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of
2、last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.1. Scope*1.1 This specification covers unsintered extruded films ortapes manufactured from virgin, unpigmented polytetrafluoro-et
3、hylene, in nominal thickness from 0.025 to 0.51 mm 0.001to 0.020 in., and are 97 % PTFE in composition.1.1.1 The use of recycled PTFE for production of unsinteredextruded films or tapes has not been identified at this time.When commercial usable processes and materials are avail-able, this specifica
4、tion will be revised to include recycledmaterials.1.2 The values stated in SI units are detailed in IEEE/ASTMSI 10 are to be regarded as the standard. The values given inparentheses are for information only.1.3 The following precautionary statement pertains only tothe test method portion, Section 8
5、of this specification: Thisstandard does not purport to address all of the safety concerns,if any, associated with its use. It is the responsibility of the userof this standard to establish appropriate safety and healthpractices and determine the applicability of regulatory limita-tions prior to use

Inspection frequency shall be adequate to ensure thematerial is certifiable in accordance with 9.4.9.4 Certification sha
28、ll be that the material was manufacturedby a process in statistical control, sampled, tested, and in-spected in accordance with this classification system, and thatthe average values for the lot meet the requirements of thespecification.9.5 A report of test results shall be furnished when re-quested
29、. The report shall consist of results of the lot-acceptanceinspection for the shipment and the results of the most recentperiodic-check inspection.10.
