Institutul Național de Metrologie București (BRML-INM)

Details regarding the calibrations and charges can be found in the List of measuring means for which the Romanian Bureau of Legal Metrology performs calibrations, LE 2016


MISSION

The fundamental mission of the National Institute of Metrology (INM) is to realise, maintain and disseminate units of measurement in Romania, in accordance with the requirements of the Mutual Recognition Arrangement of national measurement standards and Calibration and Measurement Certificates issued by the national institutes of metrology

(CIPM-MRA)

 

To achieve its mission

The National Institute of Metrology maintains, improves and uses reference measurement standards and the 21 national measurement standards of Romania.

 

PROFILE

The National Institute of Metrology is organised as a research and development institute in the field of metrology, subordinated to the Romanian Bureau of Legal Metrology (BRML).

Main activities of the INM consist in the development, maintenance and use of the national measurement standards, providing the traceability to the SI and dissemination of the units of measurement at national level.

INM operates as a public interest self-funded institution and has its own budget.

 

HISTORY

1951 - National Institute of Metrology (INM) is founded

1999 - INM signs the CIPM-MRA arrangement

2001 - INM becomes a correspondent member of the Regional Metrology Organisation EUROMET

2004 - INM is accepted as full member of EUROMET

2005 - INM becomes a member of NCSLI (National Conference of Standards Laboratories International)

2007 - INM is a founding member of EURAMET e.V.


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.

·         The list of calibration services supported by a related measurement capability

 

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.

AFFILIATION AND RECOGNITION

INM actively participates in the CIPM-MRA process, ever since the Signing of the Mutual Recognition Arrangement in 1999.

Within the EUROMET frame, INM participated in joint projects and claimed more then 300 calibration measurement capabilities (CMCs).

The acceptance of INM as a EURAMET e.V. founding member confirmed the recognition of the level attained in maintaining the national measurement standards and disseminating units of measurements, as well as in calibrating and measuring in accordance with CIPM-MRA requirements (www.bipm.org).

INM acts as the lead institute in the frame of EURAMET e.V. The designated institute in the field of Ionising Radiation is IFIN-HH (http://www.ifin.ro/research/departments/cpr.php).

Starting 2009, Romania through its INM participates in the European Research Programme in Metrology performed jointly in 22 UE members States (www.emrponline.eu).

Since 2014, INM participates in the European Metrology Programme for Innovation and Research (EMPIR) operated jointly by 28 UE member states(https://www.euramet.org/research-innovation/empir).

 

OUTLOOK

Maintenance, development and recognition of the calibration capabilities of the INM within the framework defined by the CIPM - MRA represent a permanent mission of the institute. Participation in many projects for the development and recognition of the CIPM - MRA has started and will be carried on during the next years. The calibration and measurement capabilities (CMCs) declared are validated in the frame of a documented process by the CIPM. The calibration and measurement capabilities of the INM are presented in the appendix C of the BIPM database: http://kcdb.bipm.org/AppendixC/default.asp
