Dr

(INRIM)
Summary
In this talk I will give an updated vision of the views internationally agreed on the evaluation and expression of uncertainty in measurement. Emphasis will be on the Guide to the expression of uncertainty in measurement, currently under revision, and on its Supplements. I will also present the activity in this field of the Joint Committee for Guides in Metrology, WG1. Finally, I will talk about the changes introduced in the next edition of the document, showing thus the evolution from a purely frequentist view to a Bayesian perspective.
