Academic Activities

Apart from its core mandate, i.e., dissemination of apex measurement traceability of various parameters on regular basis, Physico-Mechanical Metrology Division is also proactively engaged in performing metrology grade research in the frontier areas of metrology to upgrade the standards.

In order to support Indian Manufacturing Industries/Organization more than 1800 reports have been issued from the Division in the year 2020-21, providing apex measurement traceability to variousStrategic and Industrial Sectors, Major Private and Public Sectors Manufacturing Industries, Private and Government Research Organizations, NABL accredited and other Test and calibration laboratories etc.

Research outcomes in the form of high quality research articles are being published regularly in National and International peer reviewed journals on metrological R&D related to Physico-Mechanical parameters and on their applications.

The Division also provides need based consultancy/technical services to support Indian Industries and Institutionsin solving their challenging problems related to metrology and fulfilling their other metrological needs.

The Division also contributes significantly in conducting one-year Post Graduate Diploma (PGD) course on Precision Measurement and Quality Control (PMQC) imparting class room lectures along with hands-on laboratory experience to students for creating bank of trained man-power for Manufacturing Industries, Testing and Calibration laboratories, MSMEs, Entrepreneurs etc. under the CSIR skill development initiative program.

Programs are regularly conducted on specific parameter/disciplinestoprovide training toprofessionals from various Industries, NABL accredited labs, SAARC NMIs etc.

Lectures and various Lab based internships are also provided to B.Tech, M.Tech Trainees of other Institutions/Universities and PhD students.
