Abstract

Measurement result without defined metrological traceability does not represent valid metrological information. National laboratory for length (HMI/FSB-LPMD), as constitutive part of Croatian Metrology Institute (HMI), has a responsibility to assure traceability using national and first line standards for length, roughness and angle. In HMI/FSB-LPMD traceability for roughness parameters is assured using calibrated National roughness standards. In this paper calibration of the vertical measuring system of stylus instrument Perthometer S8P using roughness standard is presented. Calibration has been performed according to the recommendations from DKD Guideline 4-2. Based on the model shown in Directive DKD R 4-2, sheet 1, Annex A measurement uncertainty of a roughness parameter Rz determined using Perthometer S8P has been evaluated.
