    Abstract

    This specification covers the tubing that is intended for electrical, mechanical, chemical and medical applications manufactured from extrusion resins made from the copolymer of tetrafluoroethylene and hexafluoropropylene. Three types of FEP-fluorocarbon tubing are classified which are differentiated by size schedules: Type I which is tubing based upon the American wire gage, Type II which is tubing based upon fractional inch sizes, and Type III which is tubing of all other sizes. Tubings are further differentiated in accordance to its increasing wall thicknesses in classes which are Class A, Class C, Class D, and Class E. Several properties of tubing such as inside diameter, wall thickness, specific gravity, tensile strength, elongation, dielectric breakdown voltage, dimensional stability, and heat resistance shall be determined by subjecting it to different test methods.

    This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.

    1. 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 1Abbreviations are in accordance with Terminology D1600.
    Note 2There is no known ISO eqivalent 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 and health practices and determine the applicability of regulatory limitations prior to use.
