The 1987 international comparison of 1- Omega resistance standards at the BIPM and the resulting agreement among determinations of R/sub H/

To evaluate the agreement among determinations of the quantized Hall resistance, R/sub H/, at the request of the CCE (Comite Consultatif d'Electricite), the BIPM organized and conducted an international comparison of 1- Omega resistance standards among twelve laboratories. The weighted mean and standard deviation are R/sub H/=25812.8 (1+(2.059+or-0.021)*10/sup -6/) Omega /sub 69-BI/ on October 10, 1987. Values and uncertainties for R/sub H/ in Omega /sub I.AB/ and for Omega /sub LAB/- Omega /sub 69-BI/ are given.<
