Final report of SIM key comparison on 50 kg stainless steel mass standard SIM.M.M-K6 piloted by CENAM – Mexico

Main text In order to show equivalence in the calibration of 50 kg stainless steel mass standards, this key comparison was organized among eight National Metrology Institutes (NMI) of the Sistema Interamericano de Metrología (SIM). The aims of this key comparison were to compare the results obtained by NMIs in calibration of 50 kg stainless steel weights and to link the participant results to the key comparison identified as CCM.M-K6, organized by Consultative Committee for Mass and Related Quantities (CCM). For this key comparison CENAM – Mexico acted as pilot laboratory. CENAM – Mexico and NRC – Canada act as linking laboratories between this comparison and the CCM.M-K6.
