摘要：

Main text A measurement comparison of DC voltage, DC current, DC resistance, AC voltage and AC current has been carried out among seventeen national metrology laboratories with the travelling standards 6½ digit multimeter (Fluke model 8846A) as Loop A, Loop B and Loop C for the nominal values of the measured parameters DC voltage (100 mV, 1 V, 10 V, -10 V, 100 V and 1000 V), DC current (10 mA and 1 A), DC resistance (100 ω, 1 kω and 10 kω (using 4-wire), AC voltage (100 mV, 1 V, 10 V, 100 V and 700 V at 40 Hz and 1 kHz) and AC current (10 mA and 1 A at 40 Hz and 1 kHz) for establishing the degrees of equivalence among the participating NMIs. This is the final report on the comparison. The report presents the combined results (Loop A, Loop B and Loop C), represented by corrections in measured parameters and the corresponding expanded uncertainties. The combined results from the three loops have been used to calculate the Supplementary Comparison Reference Values, degrees of equivalence di and corresponding uncertainties u(di) of each laboratory that participated in the comparison. To reach the main text of this paper, click on Final Report. Note that this text is that which appears in Appendix B of the BIPM key comparison database https://www.bipm.org/kcdb/. The final report has been peer-reviewed and approved for publication by the CCEM, according to the provisions of the CIPM Mutual Recognition Arrangement (CIPM MRA). © 2023 BIPM & IOP Publishing Ltd.
