Corrosion resistance testing method for coated metal material, corrosion resistance testing device, corrosion resistance testing program, and recording medium

Disclosed is a method for testing the corrosion resistance of a coated metal material (1) which is formed by providing an electrophoretic coating film (4) on a steel plate (2). The corrosion resistance test method includes: an energization step (S2) in which a change over time in a current and/or a voltage that is obtained by applying a corrosion factor to the surface of the electrophoretic coating film (4) in a state in which the corrosion factor is brought into contact with the surface of the electrophoretic coating film (4) is measured, and an evaluation step (S3) in which the change over time in the current and/or voltage is measured. In the evaluation step (S3), a current and/or voltage generated between the surface of the electrophoretic coating film (4) and the steel sheet (2) by applying a voltage and/or current between the surface of the electrophoretic coating film (4) and the steel sheet (2) is evaluated on the basis of a waveform that changes over time. 本发明公开了一种被覆金属材料(1)的耐腐蚀性试验方法，被覆金属材料(1)是在钢板(2)上
