This specification is intended to be a means of calling out plastic product used in the fabrication of end items or parts.
Formerly under the jurisdiction of Committee D20 on Plastics, this specification was withdrawn in November 2018 since the materials in this standard are covered by other active ASTM standards. Specificationon Extruded Polytetrafluoroethylene (PTFE) Rod, Heavy Walled Tubing and Basic Shapes covers the extruded materials in D6457, while Specification on Polytetrafluoroethylene (PTFE) Resin Molded Sheet and Molded Basic Shapes covers the molded materials.
1.2 This specification covers requirements and test methods for the material, dimensions, and workmanship, and the properties of extruded- and compression-molded rod, and heavy-walled tube manufactured from granular unfilled PTFE resin in accordance with Specification D4894.
1.4 The properties included in this specification are those required for the compositions covered. Requirements necessary to identify particular characteristics important to specialized applications are described by using the classification system given in Section 4.
1.5 This specification allows for the use of recycled plastics as defined in Guide D7209.
1.7 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.
