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 or modified FEP resins containing no more than 2 % by weight of other fluoromonomers. 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 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 the 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 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, 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.
