Abstract
Main textThis is a report to the Technical Committee for Thermometry of EURAMET (EURAMET TC-T) on the regional key comparison EURAMET.T-K9 of SPRT calibration on the International Temperature Scale of 1990 (ITS-90), from 83.8058 K (the Ar triple point) to 692.677 K (the Zn fixed point). The transfer standards used are long-stem SPRTs.EURAMET.T-K9 is an RMO key comparison linked to the CIPM key comparison CCT-K9. The comparison is organized in five separate collapsed Stars, each one having a CCT-K9 participant as pilot, which provides the link to the KCRV of CCT-K9. Four to five participating laboratories are involved in each Star. The pilots of the five Stars are LNE-Cnam, PTB, INRiM, VSL, NPL. LNE-Cnam is also the coordinator of the comparison, in charge of the collection of the measurement reports from all participants and the preparation of the final report.To reach the main text of this paper, click on Final Report. Note that this text is that which appears in Appendix B of the BIPM key comparison database https://www.bipm.org/kcdb/.The final report has been peer-reviewed and approved for publication by the CCT, according to the provisions of the CIPM Mutual Recognition Arrangement (CIPM MRA).
