1、Designation: D 3296 03Standard Specification forFEP-Fluorocarbon Tube1This standard is issued under the fixed designation D 3296; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revision. A number in parentheses in

2、dicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.1. Scope*1.1 The tubing is intended for electrical, mechanical, chemi-cal, and medical applications manufactured from extrusionresins made from the copolymer of tetrafluo

3、roethylene andhexafluoropropylene (FEP-fluorocarbon). This specification isfor virgin material only and does not address recycled materialas it is not appropriate for FEP tubing.NOTE 1Abbreviations are in accordance with Terminology D 1600.NOTE 2There is no similar ISO standard.1.2 The values stated

4、 in SI units are to be regarded as thestandard. The values given in brackets are for information only.1.3 The following safety hazards caveat pertains only to thetest methods portion, Section ,8 of this specification: Thisstandard does not purport to address all of the safety concerns,if any, associ
