PROBLEM TO BE SOLVED: To provide a test device and a test method for simulating a dynamic pressure to an article exposed to caustic/corrosive fluid during actual use. SOLUTION: This dynamic pressure test machine is provided with a first cylinder 12 and a first piston capable of moving relatively to the cylinder. The piston 14 may includes one or more weights 36 added to the piston. The cylinder is vibrated by a vibration generater table 20, a pressure pulse inside the fluid is transmitted to a fixed housing 22 and a second piston 26 inside the housing. The opposite side of the second piston is brought into contact with the caustic/corrosive fluid 30 touching it in the similar manner to the sensor face of the tested article 34. The pressure pulse is transmitted to the sensor face by the second piston 26 and the corrosive fluid 30, and consequently, a dynamic pressure test can be carried out in the caustic fluid.
