On the Revision of the Gaussian Error Calculus

Two decades ago metrologists realized that the classical formalisms of Gaussian error calculus were obsolete. This is due to so-called unknown systematic errors whose influence turned out not to be negligible any more. As is well known Gaussian error formalisms exclusively process random errors. As measurements should be kept nationally and internationally comparable all the National Metrological Institutions had to standardize new procedures worldwide to be applied uniformly for the estimation of measurement uncertainties.
How should the revised Gaussian error calculus be structured? The main question referred and still refers to the problem how those unknown systematic errors should be formalized. While the National Metrological Institutions decided to essentially preserve the classical kind of Gaussian error calculus, in contrast to that, here, a rigorous revison of the Gaussian fomalisms shall be presented and discussed. Thereby, stationary measurement processes and normally distributed random errors are presupposed.
