TRACEABILITY AND CAPABILITY

The traceability of national and reference measurement standards to the International System (S.I.) is achieved by:

• comparisons with the primary measurement standards of other countries - in case of primary measurement standards held by INM;
• periodic calibration with respect to measurement standards of other international and national institutes of metrology - BIPM, PTB, BNM - INM, NPL etc. - whose traceability to the SI is already proven and widely recognized internationally.

The national standards are public goods, property of the State, represented by the Romanian Bureau of Legal Metrology, maintained, improved, compared, preserved and used within the National Institute of Metrology. The national standards are presented in Table. 1.

The types services corresponding to the specialization fields are presented in the INM laboratories section.

Calibration services for which are issued calibration certificates with CIPM MRA logo.

Other measurement and calibration services offered by INM

The INM's capability to disseminate the units in accordance with the CIPM-MRA requirements is proved by the results obtained in the key comparisons, supplementary key comparisons, as well as in other CIPM - MRA relevant comparisons performed with other institutes of metrology.
