CV supplied by the author: I have been connected with metrology for the last 56 years. I have 37 years of experience in measurement science at the National Physical Laboratory (NPL), New Delhi, India. I am among the first to write about uncertainty in measurements and Glossary of Metrological terms-documents of the Commonwealth Sciences Council CSC(80) MS-8 and various papers in Indian an International journals. I retired from National Physical Laboratory from the post of Scientist in-charge Mass, Volume, Density and Viscosity measurements in 1991. I have served 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 measurement science. I have also served as Director Weights and Measures (Legal Metrology) for a few years and brought the Standards of Weights and Measures (W&M) 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 India's W&M ACT of 1976. I am in constant touch with leading Metrology Laboratories of the world. B Academics: I am M.Sc. (Physics); M.Sc. (Mathematics); Ph.D. (Physics) with very good academic records.ssary of Metrological terms-documents of the Commonwealth Sciences Council CSC(80) MS-8 and various papers in Indian an International journals.
