Designation: D 1710 – 02

Standard Specification for

Extruded and Compression Molded Polytetrafluoroethylene (PTFE) Rod and Heavy Walled Tubing1
This standard is issued under the fixed designation D 1710; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year oflast reapproval. A superscript epsilon (e) indicates an editorial change since the last revision or reapproval.

1. Scope * 1.1 This specification covers polytetrafluoroethylene (PTFE) rod and heavy-walled tubing manufactured from the PTFE resin of Specification D 4894 and reprocessed PTFE resin (as defined in Guide D 5033). 1.2 The specification covers rod 200-mm (8-in.) nominal diameter or underand heavy-walled tubing 100-mm outside diameter and 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 practice.
NOTE 1—Although this specification and ISO/DIS 13000-1 (1997) and ISO/DIS 13000-2 (1997) differ in approach or detail, data obtained using either are technically equivalent.

1.3 The valuesstated 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. 1.4 The following precautionary caveat pertains to the test methods portion, Section 12, only of this specification: This standard does not purport to address all of the safety concerns, if any, associated with its use. It is theresponsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. 2.
