CSIR-National Physical Laboratory is the custodian of national measurement standards through an act of Parliament and provides traceability to SI units in India. CSIR-National Physical Laboratory, New Delhi in association with Metrology Society of India (MSI) organized the World Metrology Day on 20th May 2022 to commemorate the anniversary of the signing of the Metre Convention on 20th May 1875. The theme for World Metrology Day 2022 was “Metrology in the Digital Era”, announced jointly by the International Bureau of Weights and Measures (BIPM) and the International Organisation of Legal Metrology (OIML).
This theme was chosen for introducing digital measurement frameworks and requirements for an open and transparent exchange of digital information technology for revolutionising the scientific community, improving processes and providing the way for new opportunities through new digital initiatives in metrology.
On this occasion, World Metrology Day poster was released by the dignitaries. Three Bharatiya Nirdeshak Dravyas (BNDs®) namely, BND 6019 for gas, BND 4203 and BND 4204 for gold alloys, respectively, were also released. India’s first Robotic Mass Comparator was also inaugurated during this event. Robotic mass comparator is a unique facility and state-of-art facility that serves both the fundamental research and highly accurate automatic measurement in mass. The automation will help in significant reduction and potential elimination of manual handling risks and ensure highest accuracy in weights calibration. It brings many benefits to the scientist, metrologists, industries and all the stakeholders throughout the country.
