ESTABLISHMENT OF BRINELL AND VICKERS HARDNESS SCALES AT UME

Cihan Kuzu

Abstract

In this study the results of working on establishment of Brinell and Vickers hardness standards in UME Hardness Laboratory, made for several years, are presented. Brinell and Vickers hardness scales which had been aimed have been completed. Direct and indirect calibrations of the systems in accordance with ISO 6506- 3 and ISO 6507-3 were made and good results were obtained. For the indirect calibration of the systems, hardness reference blocks calibrated by PTB (National Metrology Institute of Germany) were used. In addition, Brinell and Vickers Hardness Standard Systems of UME Hardness Laboratory are introduced and their performance results are interpreted.
