How should the test force be selected for a Vickers hardness tester?

1. The selection of the Vickers hardness tester's test force should be based on the specimen type, specimen thickness, and expected hardness range. According to relevant standards, the thickness of the specimen or test layer must be at least 1.5 times the length of the indentation diagonal. After testing, no visible deformation marks should appear on the back of the specimen.
2. The indentation of the Vickers hardness test is square with a clear contour, and the diagonal measurement is accurate. Therefore, the Vickers hardness test has higher precision among commonly used hardness testing methods, and its repeatability is also very good.
