Abstract

See full text

A corrosion resistance test method for a coated metal material that includes a metal base and a surface treatment film, includes the steps of: disposing one or more water-containing material holders each holding a water-containing material to be in contact with the surface treatment film and one or more electrodes to be in contact with the water-containing material, and electrically connecting, with an external circuit, between the one electrode and the metal base, or between the electrodes; and supplying a current between the one electrode and the metal base, or between at least one of the electrodes and at least one of the other electrodes, as an anode and a cathode, to bring corrosion of the coated metal material to progress. The water-containing material comprises water, an electrolyte material, and kaolinite, and comprises the kaolinite at 36.0 mass % or more to 45.0 mass % or less.
