- Metal‐carbon eutectic mixtures show much promise for high‐temperature standards applications. A research project, Novel, High temperature, Metal‐carbon Eutectic fixed points for Radiation Thermometry, Radiometry and Thermocouples (HIMERT) was accepted by the European Union (submitted under the Framework 5 Growth Programme) with a view to developing a unified European approach to these standards. The objectives of the project are to develop fixed‐point cells both for radiation thermometry/radiometry and contact thermometry calibration applications. In total three sets of cells will be developed, two for radiation thermometry (by BNM‐INM and NPL) and one for contact sensors (by BNM‐LNE) and comparisons performed of the differing crucible designs. The cells developed for radiation thermometry will be calibrated according to the ITS‐90 and measured radiometrically by a third participant (PTB …
