Metrological characteristics of the Weston cells based on many years measurements

In This work the estimation of the usefulness of the Weston cells as the electrical voltage reference group measure standard in the hierarchical arrangement verification system are given. All Weston cells for which the measurements results are described in the paper were calibrated at Bureau International Des Poids et measures (BIPM) and the calibration results are taken into account for the analysis. The purpose of the analysis had been the answer to the question whether the Weston cells can be used in the hierarchical arrangement verification system as the voltage reference group measure standards.
