It has now completed 74 glorious years after inception and entered into its 75th year, i.e. Platinum Jubilee Year. To commemorate its 75th Foundation Day, the CSIR-NPL organized a National Metrology Conclave (NMC) on January 04, 2021. On this auspicious occasion, the Honourable Prime Minister of India, Mr. Narendra Modi dedicated the National Atomic Timescale and Bhartiya Nirdeshak Dravya (BND^®)—CRMs to the nation. He also laid the foundation stone of National Environmental Standard Laboratory. He addressed the august gathering in the gracious presence of Honourable Union Minister of Science and Technology, Dr. Harsh Vardhan. Honourable Prime Minister inspired, motivated and appreciated the strides made by Indian Scientists for nation building, especially the role of CSIR-NPL and impact of metrology for self-reliant India. Honourable Minister, Dr. Harsh Vardhan, inaugurated the exclusively designed poster gallery, displaying accomplishments and importance of metrology in the CSIR-NPL campus and released a book entitled, “Metrology for Inclusive Growth of India”. Several of the world metrology leaders also presented their visions, in the NMC, on the role of metrology in societal and industrial growth through online virtual platform. The main emphasis was placed on the importance and impact of the metrology in the success of several initiatives of Government of India, namely ‘AtmaNirbhar Bharat’ (Self-Reliant India), ‘Make in India’, ‘Digital India’, ‘Skill India’, ‘Vocal for Local’, etc. During all these years, the journey of the CSIR-NPL has been wonderful, splendid and magnificent on several aspects of celebrations, pride, recognition, global visibility and its services for the national cause.
