Concerning the paper 'On the propagation of the uncertainty at the triple point of water, associated with the calibration of SPRTs according to the ITS-90: a case study'

摘要

This letter complements our paper "On the propagation of the uncertainty at the triple point of water, associated with the calibration of SPRTs according to the ITS-90; a case study", Metrologia, 1995/96, 32, 253-257. The representation (11), used in that paper, can be considered a special case of the more general expression ΔW(T)=W(T)·ΔW(T_(0))+f[α_(1), ..., α_(n); W_(r)(T)-1], (11′) (11) being the limiting form of (11′) for temperatures approaching T_(0).
