(Specification)Standard Specification for Perfluoroalkoxy (PFA)-Fluoropolymer Tubing
Standard Specification for Perfluoroalkoxy (PFA)-Fluoropolymer Tubing
ABSTRACT
This specification covers tubing produced from PFA fluoropolymer resins which are cited in another specification. 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. Different tests shall be performed in order to determine the following properties of resins: inside diameter, wall thickness, specific gravity, tensile strength, elongation, and dimensional stability.
SCOPE
1.1 This specification covers tubing produced from PFA Fluoropolymer resins which are cited in Specification D3307. 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 D1600.
Note 2: There is no known ISO equivalent to this standard.
1.2 The values stated in SI units are to be regarded as standard. The values given in parentheses 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

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.
