Abstract. This report presents the results of a comparison of measurements on four electronic DC reference standards performed by national metrology institutes in the EUROMET region and BIPM. The results of the comparison, in terms of degrees of equivalence, show that there is a good agreement between the measurement results of the participants. The results also show that the time-dependent fluctuations in the output voltages of the travelling standards provide one of the main sources of uncertainty.
