ASTM F2129: Standard Test Method for Conducting Cyclic Potentiodynamic Polarization Measurements to Determine the Corrosion Susceptibility of Small Implant Devices.
This test method evaluates the corrosion susceptibility of small medical implant devices, individual components of the devices or other material samples, which are made of metal. Potentiodynamic polarization, in a cyclic manner (forward and reverse), is used to perform the test.
Small medical implant devices which can be assessed by this test include, but are not limited to stents (vascular and ureteral), filters, grafts, occluders, staples and aneurysm or ligation clips.
EndoLab® uses a high precision computerized potentiostat by Bank Electronics. The commonly used test fluid is phosphate buffered saline (PBS).
