ASTM D3296-24

Annotation of standard text ASTM D3296-24 :

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.
