适用范围：This part of ISO 6507 specifies the Vickers hardness test method, for the three different ranges of test forcefor metallic materials.The Vickers hardness test is specified in this part of ISO 6507 for lengths of indentation diagonals between0,020 mm and 1,400 mm.NOTE 1 For indentation diagonals less than 0,020 mm, the increase of the uncertainty has to be considered.NOTE 2 In general, decreasing the test force increases the scatter of results of the measurements. This is particularlytrue for low-force Vickers hardness tests and Vickers microhardness tests, where the principal limitation will arise in themeasurement of the diagonals of the indentation. For Vickers microhardness, the accuracy of determination of the meandiagonal length is unlikely to be better than ± 0,001 mm (see Bibliography [2]-[5]).For specific materials and/or products, particular International Standards exist.
