This paper describes how the Istituto Nazionale di Ricerca Metrologica (INRIM) performs the practical realisation of the ohm in order to transfer the traceability to the Italian accredited calibration laboratories in the field of dc and ac electrical resistance and of capacitance. These quantities are afterwords disseminated by the accredited laboratories to the Italian industry through the calibration of electric standards and electronic instruments. The INRIM primary measurement setup, the transfer method and more than 20 years of calibrations results are here presented.

Abstract
This paper describes how the Istituto Nazionale di Ricerca Metrologica (INRIM) performs the practical realisation of the ohm in order to transfer the traceability to the Italian accredited calibration laboratories in the field of dc and ac electrical resistance and of capacitance. These quantities are afterwords disseminated by the accredited laboratories to the Italian industry through the calibration of electric standards and electronic instruments. The INRIM primary measurement setup, the transfer method and more than 20 years of calibrations results are here presented.| File | Dimensione | Formato | |
