National Metrology Institute

The basis for a kilogram weighing the same in Stockholm as in Tokyo, and for efficient world trade, research and industry, is traceability through international comparisons and national standards. Without assured traceability, companies risk producing faulty products, incurring increased costs and losing the confidence of their customers. National measurement laboratories represent the top level of the metrological chain, carrying out measurements with the lowest possible uncertainty, which enables the calibration of all measuring instruments throughout the traceability pyramid. As Sweden's National Metrology Institute, RISE operates 14 national measurement laboratories covering 32 physical quantities, and represents Sweden in international metrology contexts through EURAMET and the Mutual Recognition Arrangement (MRA).

RISE's national measurement laboratories offer advanced calibrations with the lowest possible measurement uncertainties for those requiring the highest level of metrology. We maintain national standards such as the national kilogram, the UTC(SP) timescale and fixed-point cells for temperature, and we can calibrate your reference instruments directly against these. Through long-term research and development, we create new measurement methods and standards that are adapted to future technology and industrial needs. We also carry out international comparison measurements to ensure that Swedish calibration certificates are recognised globally, facilitating your exports and international collaborations.
