scope:

The purpose of this test is to determine the susceptibility of non-noble metal contact interfaces to the phenomena of fretting corrosion. Fretting corrosion is an accelerated oxidation of contact surfaces brought about by smallamplitude cyclic relative motions between mating contacts. In this test, a driving motion is imposed which tends to cause relative motion at the contact surfaces. From contact resistance measurements, one determines whether the resulting contact motion, if any, generates significant or detrimental films in the contact interface.
