After successful implementation of two hardness standardizing machines at TSE (Turkish Standards Institution) in Rockwell and Brinell-Vickers hardness scales separately, it became unavoidable to combine them in one machine with a newer design and install it in Hardness Laboratory of UME (National Metrology Institute of Republic of Turkey) within the scope of an internally funded project. In this paper the new design of the Rockwell-Brinell- Vickers hardness standard machine with deadweight force application principle and a laser interferometer optic system as depth measurement unit for Rockwell Hardness scales designed by UME Hardness Laboratory is explained.
