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.

The interlaboratory comparison (ILC) was initiated in 2019 as an important first step in the EURAMET project 1459. The aim of the ILC was first and foremost to gain knowledge later used in developing guidelines for air thermometry, particularly within the realm of calibration and dissemination of the temperature scale. While the ILC protocol asked the participants to report a set of main data that followed a rather strict formular, they were also encouraged to perform different characterisation experiments and to explore different strategies for calibration. The idea was to have a set of common baseline data and analyse them in a traditional ILC framework, but at the same time gather exploratory data that could help advance the knowledge in air temperature metrology. The results were intended to be used as input to guidance documents for the calibration of thermometers for air temperature measurements, and possibly to some initial best practice guides for practical air thermometry in the field.
