Since the necessary calculations are independent of the indenter’s size and the indenter may be used for any materials regardless of hardness, the Vickers test is frequently simpler to apply than other hardness tests. As with all accepted methods of determining hardness, the fundamental idea is to look at a material’s resistance to plastic deformation caused by a typical source. All metals can be tested with the Vickers test, which also has one of the widest hardness scales available.

The Vickers Pyramid Number (HV) or Diamond Pyramid Hardness is the term for the hardness measurement provided by the test (DPH). Although the hardness value can be expressed in pascals, pressure, which also employs the same units, should not be mistaken. The hardness number is determined by the load over the surface area of the indentation and not the area normal to the force and does therefore not pressure. These are the Vickers Scales for the NG-1000 – Micro Vickers and Knoop Hardness tester: HV0.01, HV0.025, HV0.05, HV0.1, HV0.2, HV0.3, HV0.5, HV1, HV2 (Optional).
