Abstract | At the request of the Consultative Committee for Thermometry (CCT), Working Group 4 (WG4) has critically reviewed all available measurements of the differences between thermodynamic and ITS-90 temperatures, (T - T₉₀), and documented the conversion of older data to the ITS-90. Particular attention has been given to the uncertainties. Based on this review, we provide consensus estimates of T - T₉₀ for selected measurements from 0.65 K to 1358 K. We provide two analytic functions for T - T₉₀, one for use from 8 K to the triple point of water (T TPW) and one for use above T TPW. The small discontinuity of the derivative dT 90/d T at T TPW is discussed. We also identify temperature ranges where researchers are encouraged to undertake high-accuracy measurements of T - T₉₀. |
