Abstract
The metrological equivalence of national measurement standards and of calibration certificates issued by national metrology institutes is established by a set of key and supplementary comparisons chosen and organized by the Consultative Committees of the CIPM or by the regional metrology organizations in collaboration with the Consultative Committees. During the June 2019 SIM Length Working Group meeting, it was decided to run a supplementary comparison of the measurement of long gauge blocks by mechanical comparison, SIM.L-S2.2.n02, with INTI, the National Metrology Institute (NMI) of Argentina as pilot of the comparison, and the National Research Council (NRC) Canada as co-pilot. INTI provided the gauge blocks, registered the participants, processed the results and generated the reports in collaboration with NRC who provided the reference interferometry measurements for the gauges and served as a neutral third party for collection of the results.
