Abstract

The 'Mise en pratique for the definition of the kelvin' (the MeP-K) was established in April 2006 to be the repository of information required to perform a 'practical measurement of temperature in accordance with the International System of Units (SI)'.

This paper describes the progress made by the MeP-K HT (High Temperatures task group) of CCT-WG5 (radiation thermometry) in drawing together the appropriate methods for accessing thermodynamic temperature above the silver point involving direct radiometric measurements on the one hand and indirect extrapolation, interpolation and least-squares fitting on the other. An examination of the uncertainties and a brief discussion of the advantages and disadvantages of the various approaches are given. A summary of the remaining issues to be resolved concludes the paper.
