The results of validation of the latest release of International Reactor Dosimetry and Fusion File, IRDFF-1.03, in the standard ²⁵²Cf(s.f.) and reference ²³⁵U(n_th,f) neutron benchmark fields are presented. The spectrum-averaged cross sections were shown to confirm IRDFF-1.03 in the ²⁵²Cf standard spontaneous fission spectrum; that was not the case for the current recommended spectra for ²³⁵U(n_th,f). IRDFF was also validated in the spectra of the research reactor facilities ISNF, Sigma-Sigma and YAYOI, which are available in the IRDF-2002 collection. The ISNF facility was re-simulated to remove unphysical oscillations in the spectrum. IRDFF-1.03 was shown to reproduce reasonably well the spectrum-averaged data measured in these fields except for the case of YAYOI.
