ASTM F1875: Standard Practice for Fretting Corrosion Testing of Modular Implant Interfaces: Hip Femoral Head-Bore and Cone Taper Interface

Two kinds of test methods are part of this standard, a quantitative analysis (method I) and a qualitative assessment (method II).
Method I will be used to determine the amount of damage by measuring the production of corrosion products, therefore taking a long time to test.
Normally a particle analysis as well as an ion concentration analysis of the test solution will be performed after the fatigue test.
Method IIb is a short-term electrochemical evaluation (measurement of current) to compare different designs, surface treatments and so on.
