The ASTM F2129 test method is a valuable method for determining the susceptibility of small medical implants to localized corrosion.  However, one limitation of its current form, particularly at a scan rate of 0.1667mV/sec, is testing time per specimen.  Several modifications to the ASTM F2129 method were evaluated for their impact on breakdown potentials, including: scan rates, open circuit hold method and elimination of the 100mV cathodic excursion at the start of the test.  Experiments were performed on commercially available stainless steel and nitinol wires.
