    There is widespread disagreement as to the applicability of various test procedures in the study of pitting corrosion in alloy systems. A literature survey has been made to identify areas of agreement and to rationalize areas of disagreement, especially in the area of test methods, such as potentiodynamic scanning to determine the breakthrough pitting potential, potentiostatic tests, and other electrochemical tests. The variables causing disagreement and the lack of reproducibility of test results are discussed. The current status of attempts to formulate a detailed mechanism for pitting corrosion in a given system is reviewed.
