- Abstract:
- A dead weight type Rockwell Hardness Standard Machine with a laser interferometer optic system was established to provide traceability in the field of hardness measurement for Rockwell Hardness scales at UME (National Metrology Institute of Turkey). Traceability of each component constituting Rockwell scales such as force, depth measuring system and testing cycle to national standards was provided by direct calibration. To realize performance tests of the machine as a whole, hardness reference blocks calibrated by PTB were used. In this paper, Rockwell Hardness Standard Machine of TÜBITAK UME Hardness Laboratory is introduced and its performance test results are interpreted.
