Connected with metrology for the last 54 years, 37 years of experience in measurement of mass and associated parameters at the National Physical Laboratory (NPL), New Delhi, India, among the firsts to establish the mass measurement facility including evaluation and testing of balances at NPLI. I have first-hand experience of electronic and EMFC balances, retired from National Physical Laboratory from the post of Scientist in-charge Mass, Volume, Density and Viscosity measurements, served in various countries like Cyprus, Syria, Kuwait, Vietnam and Oman as UNIDO advisor and established their measurement laboratories and trained the staff of concerned department in handlings weighing systems of all types, also served as Director Weights and Measures (Legal Metrology) for a few years and brought the Standards of Weights and Measures Act 1976 and developed various sub-ordinate legislations for effective implementation of the Act. Many neighboring and gulf countries have the Weights and Measures Acts based on our W&M ACT of 1976, in constant touch with leading Metrology Laboratories of the world.
