Linking the Results of EURAMET.T-K7 and CCT-K7 Key Comparisons

摘要：

The results of the EURAMET. T-K7 regional comparison of water triple point cells are presented. Different options in performing the link of EURAMET. T-K7 comparison to the corresponding CIPM comparison, CCT-KT, are critically considered and the final choice of the linkage mechanism is implemented. The impact of the recently refined definition of the water triple point temperature in terms of VSMOW (Vienna Standard Mean Ocean Water) on the equivalence is evidenced. The EURAMET. T-K7 reference value, calculated as the weighted mean of the participants national references, resulted about 65 μK higher than the CCT-K7 key comparison reference value, thus showing a very good agreement with the best approximation of the SI unit made in CCT-K7.
