In the framework of the International Cavitation Erosion Test (ICET), 52 cavitation erosion tests were performed in cavitation tunnels. These tests were performed by six labs in eight test groups, on five metallic reference materials. The subjects studied are: cavitation erosion trail, test specimen, calculation of mean depth of erosion (MDE), values, cavitation erosion–time curves, measuring accuracy, variation of test results, and material classification. In all these categories, deficiencies were detected such as: lack of data on eroded areas, water flow velocity at the specimen’s surface, and an evaluation misconception based on the assumption that the eroded area is equal to the specimen area. These deficiencies cast heavy doubt on the reliability of the test results. Only eighteen tests were found relevant for obtaining quantitative data. Recommendations are made to overcome some of the detected deficiencies and to improve both reliability and applicability of future cavitation erosion tunnel test results.
