1.1 This specification covers extruded polytetrafluoroethylene (PTFE) rod, heavy-walled tubing, and basic shapes manufactured from the PTFE resin of Specification and reprocessed PTFE resin (as defined in Guide ).
1.2 The specification covers all sizes of rod, tubing, and basic shapes with a wall thickness of 1.6 mm (1/16 in.) or greater. These materials must be made wholly from PTFE and produced in accordance with good commercial ram extrusion practices.
Note 1: This specification and ISO/DIS 13000-1 (1997) and ISO/DIS 13000-2 (1997) differ in approach, however, data obtained using either are technically equivalent.
Note 2: For compression molded PTFE materials, see Specification . Material that can be certified to Specification may be substituted for Specification , however the reverse in not true.
1.3 The values stated in SI units, as detailed in IEEE/ASTM SI 10 are to be regarded as the standard. The inch-pound units given in parentheses are provided for information only.
