Summary:At the SIM meeting in Buenos Aires, from 30 May 2012 to 1 June 2012, it was decided to perform a RMO Key Comparison and a Pilot Study to evaluate the performance of SIM national metrology institutes for measuring electrolytic conductivity. The Brazilian Institute of Metrology, INMETRO, agreed to act as coordinating laboratory. The proposed RMO Key Comparison aims to investigate the equivalence of electrolytic conductivity measurement results around 0.05 S m-1 at 25 °C. Four institutes took part in the comparison. There was a good agreement of the reported results with the average value, considering the measurement uncertainties.
