The aim of this project is to compare the results of the calibrations of a 20, a 50 and a 250 L proving tank. The comparison will allow the participating laboratories to test whether their results and uncertainties are in agreement with the results of the other participants and provide support to the CMC claim for this type of calibration. VNIIM provides the proving tanks that will be used for the comparison. The proving tanks are of the overflow type. The measurements to determine the repeatability of the proving tanks will be performed by VNIIM.
VNIIM is the pilot lab for the comparison. VSL is the coordinating lab.
