Abstract
A corrosion resistance test method for a coated metal material, the method including: a preparation step of arranging one or two containers holding a water-containing material and one or two electrodes, and electrically connecting the electrode and the metal base to each other or the two electrodes to each other; a current supply step of supplying a current between the electrode serving as an anode and the metal base serving as a cathode or between one of the two electrodes serving as an anode and the other electrode serving as a cathode to cause corrosion of the coated metal material to progress; a calculation step of calculating a progress degree of the corrosion; a correction step of correcting the progress degree based on a posture of the test target portion; and an evaluation step of evaluating corrosion resistance based on a correction value for the progress degree.
