Abstract :
To evaluate the agreement among determinations of the quantized Hall resistance, RH, at the request of the CCE (Comite Consultatif d´Electricite), the BIPM organized and conducted an international comparison of 1-Ω resistance standards among twelve laboratories. The weighted mean and standard deviation are R H=25812.8 [1+(2.059±0.021)×10-6] Ω69-BI on October 10, 1987. Values and uncertainties for RH in ΩI.AB and for ΩLAB-Ω69-BI are given
