(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 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 known ISO equivalent to this specification.
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 and health practices and determine the applicability of regulatory requirements prior to use.
