Abstract

PURPOSE:To improve a reproducibility of a corrosion state as well as to perform a test in a short time by a method wherein sulfuric acid or a sulfuric acid compound is added to a salt water and it is used as a test liquid. CONSTITUTION:Each sample 1 is dipped in a test liquid for a defined time by a time by a timer 12 by means of ascending a piston rod 5a of an air cylinder 5. And after a defined time, the piston rod 5a is made to lower to dry each sample 1 within a drying chamber 4 for a defined time by the timer 12 and thereafter, dipping is performed once more to perform an operation of repeating of dipping- drying. As a test liquid, a test liquid in which sulfuric acid or a sulfuric acid compound is added to a salt water is used.
