## Abstract Various characteristic pitting potentials are defined which may be observed in a system simultaneously. Following these definitions, galvanostatic polarization techniques are expected to result in potential oszillations whenever the pit nucleation potential, U~np~, differs from the crit

Abstract
Commonly used electrochemical methods of determination of characteristic potentials for pitting are briefly described and compared. The possibility to predict an βabsoluteβ and/or relative pitting resistance of a material from measurements of the characteristic potentials is discussed. Factors and parameters affecting the measurements are summarized.
