Standard Specification for FEP Resin Tube
Standard Specification for FEP Resin Tube
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. 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 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.
ASTM D3296-24: Standard Specification for FEP Resin Tube defines the requirements for tubing produced from FEP (fluorinated ethylene propylene) resins. These tubes are intended for a wide range of applications across electrical, mechanical, chemical, and medical industries. The specification applies exclusively to virgin extrusion resins made from the copolymer of tetrafluoroethylene and hexafluoropropylene (FEP), with an allowance for up to 2% by weight of other fluoromonomers. This standard ensures that the tubing meets critical performance and quality benchmarks, supporting reliable and consistent use in demanding environments.
The ASTM D3296-24 standard is valuable across several sectors, delivering reliable performance where chemical resistance, electrical insulation, and mechanical robustness are paramount. Key applications include:
