    Abstract

    ASTM Subcommittee G01.11 on Electrochemical Measurements in Corrosion Testing has conducted round-robin testing on the reproducibility of cyclic potentiodynamic polarization measurements for determining susceptibility to localized corrosion. This work was used in the development of a practice that provides a standard experimental procedure for conducting these tests. This paper presents the experimental procedure and results of the round-robin tests with statistical analysis of the data. The reproducibility of the measurements and sources of error are discussed.
