Apex Level Standards & Industrial Metrology

Division objective is to strengthen and encourage the overall development in the field of science and technology for the country. The main responsibility is the realization, establishment, custody, maintenance, dissemination and upgradation of the national standards for Physico-mechanical, Electrical, Optical and Thermal precision parameters involving twelve groups. Established the National Measurement Standard (NMS) System with international traceability. The division offers various apex level calibration services to the industry & user organizations of the country and provides educational training on industrial metrology to support the economic growth. At this moment CSIR-NPL has 246 CMC and 149 International Key/Supplementary intercomparisons at the BIPM website. In the XIIth five year plans, our major emphasis is to develop the quantum standards. India is the member of Meter convention since 1957 and out of 12 Consultative committees, India is the full member in three Consultative committees namely, CCEM, CCM and CCTF.
