T1  - Thermodynamic temperature measurements of the melting curves of RE-C, TIC-C And ZRC-C eutectic irradiance mode fixed-point cells
T2  - Proceedings TEMPMEKO 2004
N2  - The thermodynamic temperatures of the phase transition of Re-C, TiC-C, and ZrC-C eutectic fixed-point cells have been measured for the first time using different filter radiometers in irradiance mode. The spectral responsivity of these filter radiometers was measured traceable to the primary detector standard of the PTB, a laser based cryogenic radiometer. The relative extended uncertainties of the spectral responsivities of the filter radiometers in the irradiance mode were in the range from 5· 10-4 up to 2.5· 10-3. The measurements have been performed at the high temperature calibration facilities of the VNIIOFI and the PTB with eutectic fixed-point cells manufactured by VNIIOFI.
