Abstract:
This paper describes a primary Vickers hardness standard, which was developed by National Institute of for Standards (NIS), of Egypt. It is utilized synthetically the optics, precise mechanism, electronics, computer and automatic controlled technology. The CCD image system is employed, which makes the standard measuring of Vickers hardness value automatically and manually, so the indentation can be realized and accuracy can be improved .The machine has been evaluated through comparisons with the Physikalisch-Technische Bundesanstalt (PTB) Germany.
