The report summarises the results of the EURAMET.T-K8 key comparison (EURAMET Project No. P 717) in the field of humidity. The comparison covers the dew-point temperature range from +30 °C up to + 95 °C dew point temperature. The report gives details of the scheme, procedure and analysis of the comparison. The overall results display a very good agreement of the 16 participating laboratories. The two dew-point hygrometers used as travelling standard were sufficiently stable. The linkage to the corresponding CCT-K8 comparison will be calculated when the final results for both comparisons are available. Possible procedures are described in the text. In the conclusion, some remarks for improvement for future RMO key comparisons are given.

Final report to the CCT on key comparison CCT-K8 - comparison of local realisations of dew-point temperature of humid gas in the range 30 °C to 95 °C
(IOP Science, 2025-02-04) García Gallegos, Jaime; Mitter, Helmut; Abe, Hisashi; Benyon Puig, Robert; Carroll, P.; Choi, B. I.; Deschermeier, Regina; Ebert, V.; Fernicola, Vito; Wang, L.; Meyer, C.; Smorgon, Denis; Vicente Mussons, Tomás
The report summarises the results of the CCT-K8 key comparison in the field of humidity. The main target of this comparison was to obtain the degree of equivalence (DoE) between realizations of local scales of dew point temperature of humid gas (air), in the range from 30 °C to 95 °C, among the participating national metrology institutes. The report gives details of the scheme, procedure and analysis of the comparison. The overall results display a very good agreement of the nine participating laboratories. The results show excellent agreement between the realized scales with no detected outliers. The performance of the travelling standards was excellent and can be attributed to the intensive preconditioning and selection of the platinum resistance thermometers, prior to their integration into the measuring head assembly, that led to insignificant drift. In the conclusion, some lessons learned are reported that could be beneficial for future key comparisons.
