Abstract
This specification covers the requirements for wrought seamless and welded and drawn cobalt alloy small diameter tubing used for the manufacture of surgical implants. Product variables that differentiate small diameter medical tubing from the bar, wire, sheet, and strip product forms are addressed. This specification applies to straight length tubing of specified diameters and thickness. Seamless tubing shall be made from bar, hollow bar, rod, or hollow rod raw material forms through a prescribed process. Welded and drawn tubing shall be made from strip or sheet raw material forms that meet the specified chemical requirements. The tubing shall be subject to tensile testing.
Scope
1.1 This specification covers the requirements for wrought seamless and welded and drawn cobalt alloy small diameter tubing used for the manufacture of surgical implants. Material shall conform to the applicable requirements of Specifications F 90, F 562, F 688, F 1058 or F 1537, Alloy 1. This specification addresses those product variables that differentiate small diameter medical tubing from the bar, wire, sheet and strip product forms covered in these specifications.
1.2 This specification applies to straight length tubing with 0.250 in. (6.3 mm) and smaller nominal outside diameter (OD) and 0.030 in. (0.76 mm) and thinner nominal wall thickness.
1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
