Main text The purpose of this comparison was to compare the results of the participating laboratories at the triple point of water temperature (TPW) and assess the uncertainty on the practical realization of triple point of water temperature by the participant laboratories and also to support the Calibration and Measurement Capabilities (CMC) entries of the participating laboratories for this fixed point. This comparison was initiated as a EURAMET project with project number 1357. Initially, the participants of the comparison included the Metrology Institutes of Albania (DPM), F.Y.R Macedonia (BOM), Montenegro (MBM) and Serbia (DMDM). But at the later stages of the comparison, these countries understandably chose to leave the comparison instead of repeating the measurements due to an unexpected problem. On the other hand, participants from GULFMET organization, Emirates Metrology Institute (EMI) and National Measurement and Calibration Center at Saudi Standards, Metrology and Quality Organization of the Kingdom of Saudi Arabia (SASO NMCC) and also Jordan National Metrology Institute (JNMI) were included in the comparison after having approvals of each participating laboratory. Then the comparison was registered as Key Comparison with the name EURAMET.T-K7-4 in BIPM KCDB. Finally, two loops was combined together and five institutes performed the comparison with the single circulating TPW Cell. This report presents the results of the TPW comparison and gives detailed information about the measurements made at TUBİTAK UME and participating laboratories.
