ASTM D3296-03
(Specification)Standard Specification for FEP-Fluorocarbon Tube
Standard Specification for FEP-Fluorocarbon Tube
SCOPE
1.1 The tubing is intended for electrical, mechanical, chemical, and medical applications manufactured from extrusion resins made from the copolymer of tetrafluoroethylene and hexafluoropropylene (FEP-fluorocarbon). This specification is for virgin material only and does not address recycled material as it is not appropriate for FEP tubing.
Note 1—Abbreviations are in accordance with Terminology D 1600.
Note 2—There is no similar ISO standard.
1.2 The values stated in SI units are to be regarded as the standard. The values given in brackets are for information only.
1.3 The following safety hazards caveat pertains only to the test methods portion, Section 8, 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.
