We present a new normalization condition for the axial current, which is derived from the PCAC relation with non-vanishing mass. Using this condition reduces the O(rom) corrections to the axial current normalization constant ZA for an easier chiral extrapolation in the cases, where simulations at ze

Renormalization constants of vector (2,) and axial-vector (ZA) currents are determined non-perturbatively in quenched QCD for an RG-improved gauge action and a tadpole-improved clover quark action using the Schr6dinger functional method. Meson decay constants f, and fT show much better scaling when
