Abstract

Procedure for evaluation of uncertainties of the ITS-90 based on the propagation of distributions using the Monte Carlo method is presented. It is based on generation of pseudo-random numbers for input variables of the multivariate Gaussian distribution. This allows to take into account the correlations between the resistances at the defining fixed points. Assumption of Gaussian probability density function is acceptable with respect to the several sources of uncertainties of resistances.
