61. Uncertainty Budgets for Realization of ITS-90 by Radiation Thermometry
Published: 1/1/2003
Authors: J Fischer, M Battuello, M Sadli, M Ballico, S N Park, P Saunders, Y Zundong, Bettye C Johnson, E Van der Ham, F Sakuma, Graham Machin, N Fox, W Li, S Ugur, M Matveyev
Abstract: Recent international comparisons [1,2] and key comparisons have shown that the realization of the ITS-90 above the freezing point of silver and its dissemination may be less straightforward than expected. In many cases, the deviations of the local s ...
