Polarization tests constitute one of the most useful tools available to the corrosion engineer in the determining of cathodic protection current requirements; yet, polarization tests are probably the least used method in determining this all important information. A portion of this lack of use is due to lack of understanding of the nature of polarization, and to a further lack of understanding of the proper method to be followed in conducting the tests. This chapter attempts to provide a basis for the corrosion engineer's working understanding of polarization criteria. The theory involved will be reduced to basic levels so that use and appreciation of the tests do not become clouded in endless equations and precise definitions of laboratory conditions which are impossible to duplicate in the field.
