The triple point of water defines the unit of thermodynamic temperature, kelvin, and is the most important fixed point of the International Temperature Scale of 1990. Several international comparisons of cells for the realization of the water triple point were carried out to estimate the temperature values obtained in real conditions at national metrology institutes. A separate bilateral comparison was set up for INTiBS, Poland with INRiM, Italy, as CCT-K7 participant, in order to create a direct reference to CCT-K7 for the Polish institute. Results of the bilateral comparison carried out as EUROMET project no 895 are presented in this paper.
