This article describes the progress made by the MeP-K HT (High Temperature 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 article.}, language = {en} } @inproceedings{HartmannMcEvoyMachinetal., author = {Hartmann, J{\"u}rgen and McEvoy, H.C. and Machin, Graham and Friedrich, R. and Hollandt, J{\"o}rg}, title = {Comparison of the New NPL Primary Standard Ag Fixed-Point Blackbody Source with the Primary Standard Fixed Point of PTB}, series = {AIP Conference Proceedings (684)}, booktitle = {AIP Conference Proceedings (684)}, publisher = {American Institute of Physics}, isbn = {0-7354-0153-5}, pages = {909 -- 914}, abstract = {Above the freezing point of silver (961.78 °C), the International Temperature Scale of 1990 is defined in terms of Planck's radiation law. The scale is maintained and disseminated using a validated and linear pyrometer in conjunction with a blackbody reference source at either the Ag, Au (1064.18 °C) or Cu (1084.62 °C) freezing point. In order to realize the scale with the highest precision high quality, well-characterised, reproducible fixed-point blackbody sources are required. Such sources have been maintained at NPL for a number of years, but it was felt that improvements to the design would be beneficial. A new Ag point blackbody source has therefore been constructed. The new design will improve the quality and reproducibility of the melting and freezing plateaux and reduce errors due to the 'out-of-focus' size-of-source effect which is difficult to measure and to eliminate.
