PURPOSE:To enable a simultaneous testing of a number of test pieces under the same environment by mounting the test pieces detachably at the tip of a support rod fastened on the inner wall of a container at an arbitrary angle to an impeller. CONSTITUTION:A plurality of test pieces 4 are mounted close to the circumferential surface 3a of an impeller 3 and the other ends thereof are mounted detachably at the tip of a test piece support rod 5 fastened on the inner wall of a container 1 at an arbitrary angle theta to the impeller 3. The test pieces 4 hit the pass of a corrosion testing liquid following the rotation of the impeller 3 and as a result, undergoes an erosion and a corrosion. Thus, it is possible to decide on whether the test pieces 4 are put under the erosion or the corrosion as desired. |
