This specification covers the chemical, mechanical, and dimensional requirements for wrought seamless nickel-titanium shape memory alloy tubes used for the manufacture of medical devices and surgical implants. Tubes shall be furnished in the superelastic condition, and the outer surface shall have a pickled, ground, or mechanically polished finish, or as agreed upon between purchaser and supplier. This specification addresses those product variables that differentiate drawn medical grade tube from the raw material and mill product forms. This specification applies precisely to tube with 10 mm (0.4 in.) and smaller nominal outside diameter and 2 mm (0.08 in.) and thinner nominal wall thickness. The mechanical properties to which the tubes shall conform are ultimate tensile strength (UTS), uniform elongation, upper plateau strength, lower plateau strength, and residual elongation.
