Abstract

Techniques are recommended for comparisons, at the highest levels of accuracy, of fixed-point cells of the defining fixed points, excluding the vapour-pressure points, of the ITS-90, which are used for contact thermometry. The authors are the members of Working Group 1 of the Consultative Committee for Thermometry (CCT) of the Comite International des Poids et Mesures, dealing with Defining Fixed Points and Interpolating Instruments underlying the realization of the ITS-90.
