Emissivity and Temperature of Fusion

The aims of this work package are:

• to establish a reference facility for the traceable measurement of the emissivity of solid materials above 1500 °C based on radiometric or calorimetric methods using pulse or induction heating and
• to use measurements from this new facility to compare results of total hemispherical and normal spectral emissivity measurements obtained with existing facilities.
• to develop validated methods for the measurement of the temperature of fusion of refractory materials up to 3000 °C.

The work will be split into three tasks:

• the development of reference facilities and methods with calibration procedures
• the metrological validation of the developed methods with uncertainty budgets
• the application of the methods on industrial materials
