| Zusammenfassung | Melting and freezing temperatures of Ir-C and Re-C eutectic fixed-point blackbody cavities were determined for the first time during a joint experiment using detectors from NPL, PTB and VNIIOFI which were all radiance-mode narrowband interference-filter based detectors calibrated against either national realisations of the Temperature Scale ITS-90 or radiometric detector scales. The average values of the observed melting temperatures for one Ir-C and one Re-C eutectic crucible were 2564.3 K and 2748.5 K, respectively. The corresponding values for the freezing points were 2564.6 K and 2748.2 K, respectively. The standard deviations were not larger than 0.2 K, which is well below the individual calibration uncertainties of the detectors. |
