Fundaments of metrology
Paragrafo

TITOLARE DEL CORSO
Filippo Levi

DESCRIZIONE
The course aims to give a general view of the fundaments of metrology by presenting the international metrological organization, giving basic statistical elements to properly analyze uncertainties, and presenting the new SI and its measurement units. INRIM scientists will give lectures on the various topics proposed.

ARGOMENTI TRATTATI
1

a. History of the measurement units and the Convention of the meter
b. BIPM, regional organizations, MRA
2. Uncertainty of measurements: GUM, type of uncertainties, criteria for expression of uncertainties, basic mathematical tools for proper use of uncertainties (6 hours)
3. The new SI: the role of fundamental physical constants (22 hours)
Description of the SI units and their practical realizations:
