MISSION OF THE NATIONAL METROLOGY INSTITUTE SMD - ENS

ASSURE THE QUALITY OF MEASUREMENTS: Assure traceability to SI standards; Realisation and management of the national SI standards; Assure international recognition of our measurements and calibrations.

GIVE SUPPORT TO INNOVATION: Develop and improve the national SI standards; Develop and improve transfer techniques of these standards to the final user; EMRP – EMPIR activities.

TRANSFER OF METROLOGICAL KNOWLEDGE: Expertise and consultation tasks; Continuous transfer of knowledge (advice, presentations, training…).

For economic and scientific sectors:

ASSURE THE QUALITY OF MEASUREMENTS


Assure traceability to SI standards

Traceability: property of a measurement result whereby the result can be related to a reference through a documented unbroken chain of calibrations, each contributing to the measurement uncertainty”. Only traceable measurements, given with their uncertainty values are comparable

2. Quality of the measurement and

3. Equivalence to other similar measurements

TASKS AND OBJECTIVES OF THE NATIONAL METROLOGY INSTITUTE SMD - ENS

The actions set up to ensure our services in an optimal way are: • routine calibrations

• collaboration with and support to industrial metrology and research

• a special attention towards the nanometrology through investments and an

innovating development programm

• the implication in European research programs in metrology (EMRP, EMPIR and Euramet)

• the technical and scientific support to the Belgian organizations Belac and Belmet and to research centers and industry

• the participation in activities and international comparisons of Euramet and BIPM.
