The procedure of the estimates of the higher-order perturbative QCD corrections to the physical quantities is generalized to the case when the quantities under consideration obey the renormalization group equations with the corresponding anomalous dimension functions. This procedure is used to estimate the α 3 s-corrections to the singlet part of the Ellis-Jaffe sum rule for f = 3 numbers of flavours.
