| Manufacturer and type: | Mitutoyo Hardness Testing Machine HV, Model No. 810-165D |
| Purpose: | Hardness testing machine is used to determine the hardness of the material by penetration method, that is by measuring the resistance of materials to the penetration of a harder material into its surface. The measuring is carried out according to the Vickers method. |
| Kratki opis metode: | The Vickers hardness measurement method is based on measuring the size of the diagonals that are imprinted by a four sided diamond pyramid in the material. Hardness is the ratio of the force and the surface of the pyramid imprint. |
| Tehničke značajke: | The basic characteristics of the device are: the amount of load can be selected from 1 to 50 N, the force retention time can be set in range from 5 to 99 s. After measuring the diagonal reading device provides the hardness, HV, with the possibility of conversion to other units. |
| Standard: | EN ISO 6507-1 |
| Tip i priprava uzorka: | Solid samples of the round or rectangular cross-section, in accordance with norms used for testing. Samples must have parallel surfaces and need to be prepared by fine grinding and polishing of the surface to be tested. Dimensional constraints: the lower surface of samples up to the 50 mm in diameter, an samples height up to 40 mm. |
| Laboratory: | Laboratory for machining of deformation metal |
