PROBLEM TO BE SOLVED: To provide a corrosion-proof testing device for performing safely a corrosion test by salt water, hydrofluoric acid, sulfuric acid or nitric acid in the air, hydrogen or oxygen. SOLUTION: In order to prevent explosion or to minimize a damage caused by explosion, this corrosion-proof testing device has (A) a means for replacing the inside of a test vessel with gaseous nitrogen before hydrogen supply into the test vessel and after discharge thereof, (B) a means for installing the test vessel in a temperature/humidity conditioning chamber having a rupture prevention means and performing temperature control of the test vessel indirectly, (C) a monitoring means of gas discharged from inside the the test vessel to the outside, (D) a monitoring means and a control means of gas in the test vessel, and (E) a means for adjusting the pressure of supplied corrosive gas in the range over 0.1 MPa and below 0.3 MPa.
