The Vickers hardness test is a static hardness test method, used for both macro and microhardness testing. . Place the specimen carefully on the testing table. Bring the objective to the "set" position. . The obtained results are reported as 800 HV/10, where 800 is the Vickers hardness and 10 is the load applied. But it is a general .NOTE 2 In general, decreasing the test force increases the scatter of results of the measurements. This is particularly true for low-force Vickers hardness tests and Vickers microhardness tests, where the principal limitation will arise in the measurement of the diagonals of the indentation.Table of Contents. When testing the . For example, if you are using the Rockwell hardness test on a metal part, you need to convert your test results from the Rockwell scale to the Vickers scale. Various scales are used when measuring the hardness of materials because each has advantages depending on the properties of the material being . The Vickers hardness test combines the advantages of both the Brinell and Rockwell tests, suitable for materials from extremely soft to extremely hard, and their results can be compared. The Knoop hardness test, as one of the static test methods, is suitable for various materials, but further understanding of its specifics is needed.
