A prototype comparison of the ITS-90, as realized by NPL, NIM, and CEM, using high-temperature fixed points (HTFPs) of Co-C (1324 °C), Pt-C (1738 °C), and Re-C (2474 °C), is reported. The local realizations of ITS-90 temperatures were assigned by NPL, NIM, and CEM to their own set of HTFPs. NIM and CEM then transported their cells to NPL, and the ITS-90 temperatures of all three sets of cells were...
We report about the data analysis of this first formal scattering parameter comparison of the coaxial 2.4mm system. Multivariate statistics and a Monte Carlo method are applied to determine a comparison reference value (CRV) with a 95% confidence region
