ASTM F3044: Test Method for Standard Test Method for Evaluating the Potential for Galvanic Corrosion for Medical Implants
This test method assesses the occurrence of galvanic corrosion of two dissimilar metals in electrical contact which are intended to be used as medical implants or components of it. Phosphate buffered saline (PBS) is used as standard test fluid; other simulated physiological solutions are possible (as listed in Test Method ASTM F2129, Appendix X2).
EndoLab® uses a high precision computerized potentiostat by Bank Electronics. A visual inspection of the implants, according to standard ASTM F3044-14 by means of a stereomicroscope, is performed before and after the test.
For the evaluation of the results the corrosion rate is calculated. This is based on the average current and potential data of the last fifteen minutes of the test.
