Some recent international comparisons and the preliminary results of the key comparison CCT-K5 evidenced that the realisation of theITS-90 above the freezing point of silver and its dissemination with tungsten strip lamps may be less straightforward than expected. Inmany cases, the deviations of the local realisations were higher than the combined estimated uncertainties. On the other hand, it must beconsidered that the realisation of the ITS-90 by radiation thermometry is a complex exercise involving a large number of operations andwith many influencing parameters.
