Organization: ASTM
Publication Date: 1 May 2015
Status: inactive
Page Count: 14
ICS Code (Thermosetting materials): 83.080.10
scope:

This specification2 covers polytetrafluoroethylene (PTFE) prepared by coagulation of the dispersion. These PTFE resins are homopolymers of tetrafluoroethylene or modified homopolymers containing not more than 1 % by weight of other fluoromonomers. The materials covered herein do not include mixtures of PTFE with additives such as colors, fillers, or plasticizers; nor do they include reprocessed or reground resin or any fabricated articles because the properties of such materials have been irreversibly changed when they were fibrillated or sintered.

The values stated in SI units as detailed in IEEE/ASTM SI-10 are to be regarded as standard. The values given in parentheses are for information only.

The following safety hazards caveat pertains only to the Specimen Preparation Section, Section 9, and the Test Methods Section, Section 10, of this specification: 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. See Warning note in 9.1.1 for a specific hazards statement.

NOTE 1-Information in this specification is technically equivalent to related information in ISO 12086-1 and ISO 12086-2.

2 Specifications for other forms of polytetrafluoroethylene are found in Specifications D4441 and D4894.
