Indirect measurements of the quantized Hall resistance {rho}{sub xy} =R{sub H}(i) are carried out on the i=1 and i=2 plateaus for an AlGaAs/GaAs heterostructure cooled at 1.2 K under both directions of magnetic field. The mean value of the ratio k (i = 1)/P.H (i = 2) differs from the value 2 by + 0.3 part in 10{sup 9} with a combined relative uncertainty (1 {sigma}) lower than 3 parts in 10{sup 9}.
