This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
Designation:D6867–03 Designation: D 6867 – 03 (Reapproved 2009)
Standard Specification for
Perfluoroalkoxy (PFA)-Fluoropolymer Tubing
This standard is issued under the fixed designation D 6867; 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 of last reapproval. A
superscript epsilon (´) indicates an editorial change since the last revision or reapproval.
1. Scope
1.1 This specification covers tubing produced from PFA Fluoropolymer resins which are cited in Specification D 3307. This
document specifies tubing dimensional tolerances, tensile properties and related electrical properties as noted in the appropriate
tables when tested in accordance with the methods cited in this specification.This specification is for virgin material only and does
not address recycled material, as it is not appropriate for PFA tubing.
NOTE 1—Abbreviations are in accordance with Terminology D 1600.
NOTE 2—There is no similarknown ISO standard. equivalent to this specification.
1.2 The values stated in SI units are to be regarded as the standard. The values given in bracketsparentheses are for information
only.
1.3 The following safety hazards caveat pertains only to the test methods portion, Section 7, 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 requirements prior to
use.
