Sažetak
Reference hardness standard with HV1 – HV50 measuring range was installed at LIMS (Laboratory for Testing Mechanical Properties) at the end of 2007 with the aim of providing continuous improvement of the metrology infrastructure of Croatia. The evaluation of the measurement uncertainty is one of the most important tasks for establishing this reference standard. Therefore, the influence quantities contributing to the uncertainty were determined and the machine calibrated by direct and indirect method. In this paper the results of the measurements are presented and discussed.
