Abstract
Main textIn order to validate the participants' calibration measurement capabilities (CMCs) and to provide a basis for the submission of reviewed or new CMCs for National Metrology Institutes of member countries of the "Comité International des Poids et Mesures" (CIPM), supplementary comparisons of mass standards have been carried out under the auspices of the EURAMET. This is a comparison of the 20kg stainless steel mass standard. The aim of this supplementary comparison was to compare the results obtained by NMIs in the calibration of 20kg stainless steel weights. BEV, Austria was the pilot laboratory. Measurements were performed between 15 May 2022 and 28 June 2024. The data analysis was carried out by Dr Lars Nielsen (DFM). The participants' results were in agreement with the comparison reference value except one laboratory (SMU, Slovakia), after two laboratories updated their values.To reach the main text of this paper, click on Final Report.
