Traceability in infrared radiation thermometry

Objective

Infrared radiation thermometry is extensively used in many industrial sectors. Presently, in Europe, two traceability systems for infrared radiation thermometry can be distinguished in relation to the reference standards chosen to define the regional scales:
Compact fixed-point blackbody radiators, carrying the fixed points as defined in the ITS-90, providing the means for the calibration of interpolating transfer radiation thermometers.
Standard platinum resistance thermometers, carrying the ITS-90, and defining the temperature of reference blackbody radiators, continuously variable in temperature, serving as a means for the calibration of infrared thermometers.
These two systems need to be elaborated and compared at the highest levels available, in order to investigate whether or not one of them should be selected as the standard for traceability in Europe.

The overall objective of the project is to provide improved, sub-Kelvin accuracy in infrared radiation thermometry to industrial levels in the temperature range from - 50°C to 800°C by developing an effective traceability system, including a unified practical temperature scale for radiation thermometry in this temperature range, with an inherent accuracy approaching 0,1 K. The project implicitly envisages regional scales in development in the smaller partner states in northern and southern Europe being integrated in such a harmonised European traceability system.
The project is in progress. Guidelines for the development, testing and characterisation of the low and medium temperature transfer radiation thermometers and reference blackbody radiators have been produced.
