A proposal for a new approach to the GUM

We propose a new approach to addressing the expression and evaluation of uncertainty in measurement, which at the one hand maintains the same original goals of the Guide to the Expression of Uncertainty in Measurement (GUM), as expressed by the original recommendations from the CIPM, on the other significantly differs in proposing how to implement them, for a closer orientation to the needs of the expected users, supported by a sound theoretical background. We suggest that this new approach may overcome some of the setbacks that have been experimented in the years in the application of the GUM, thus helping a wider diffusion of the practice of evaluating measurement uncertainty, by establishing a close link with the current state of the art of measurement science.
