Abstract
A painting fiber probe having a measurement surface on which a coating film is formed with the same painting specification as that of a sample (painted steel sheet) is placed in a test tank together with the sample. A cycle consisting of three steps of saline water spraying, drying and wetting is repeated on the sample and the painting fiber probe. In the drying step of the cycle, absorbance at a specific wavelength of the coating film formed on the painting fiber probe is measured at a regular interval and drying is ended when the measured absorbance satisfies a predetermined condition.
