They maintain a database of the metrological calibration and measurement capabilities of various institutes around the world. These institutes, whose activities are peer-reviewed, provide the top-level reference points for metrological traceability

Applied, Technical or Industrial Metrology

This branch deals with application of measurement. In our today?s industry metrology plays very important role where every thing need to be measure very accurately to smooth running of the automated process.
