 Summary:
 Metrological assurance comprises determination of metrological features of instruments and accesories, during the calibration process, before usage. A level, together with levelling rods, is a subject of calibration. The calibration results at Serbian National Metrological Institute (Directorate for Measures and Precious Metals - DMDM) and respectable scientific institutions, Faculty of Civil Engineering in Belgrade (GFUB) and Faculty of Civil Engineeringin Ljubljana (GFULJ) will be presented in this paper. In order to confirm the method realiabillity and calibration data in mentioned institutions, calibration of the precise levelling rod is performed. The results obtained in laboratories are transformed in statistical quantities due to their easier interpretation and comparison. Obtained results are used for statistical analysis following the procedures of interlaboratory comparison, defined with ISO/IEC 17043 standard.
