Standard practice for fretting corrosion testing of modular implant interfaces: hip femoral head-bore and cone taper interface

The ASTM F1875 standard describes how to test, characterize and analyze the mechanical stability of the bore and cone interface of the head and stem junction of modular hip implants subjected to cyclic loading by measurements of fretting corrosion.

The following fretting corrosion test methods are described:

• Method I - long-term testing
• Method II - short-term electrochemical testing either as Method II, Procedure A (measurement of the corrosion potential) or as Method II, Procedure B (measurement of the corrosion current)
