Mass Metrology Division
Introduction
Mass Metrology Division (MMD) was established to meet the requirements of quality system as per International Standards ISO/IEC 17025. Calibration services for Mass and Volume are accredited by PNAC.
The Division provides calibration and measurement services in the fields of Mass, Volume, Density and Hardness to a large number of customers from public, defense and private sectors’ laboratories and industries
Funtions
The main functions of Mass Metrology Division (MMD) are
- Realization and maintenance of National Primary Standards of Mass &Volume
- Dissemination of mass standards of E1, E2, F1 & F2 class and volume measures of different capacities ranging from 10 µL to 50 L
- To conduct R&D activities for improving the existing measurement techniques in the field of Mass & Volume Metrology
- To provide on-site calibration to customers for mass balances having capacity from 5 g to 5000 g and readability from 1 µg to 100 mg
- To extend training services to different customers in the field of mass and volume metrology
- To carry out designing, development and production of secondary and working standard of masses from 1 mg to 20 kg of F1, F2 class and volume measures according to OIML recommendations
- Participations in ILC/PT program of mass and volume standards for maintaining the measurement traceability
- To provide measurement services for density, specific gravity of different liquids and calibration of specific gravity meters/hydrometers
-
To provide calibration services for hardness standard of Rockwell, Vickers and Brinell scales
- To impart training to personnel working in industry and other organizations on calibration techniques in the field of Mass & Volume Metrology
