1 NPL, India activity related to water as per the need of the country, Ph.D. (Sr. Scientist) Chemical & Food BND Group Indian Reference Materials (BND) Division CSIR-National Physical Laboratory, New Delhi, APMP GA 2018_Clean Water Focus Group 23rd November 2018_Singapore
2 Focus Technical capability in measurement of quality of water Development of Certified Reference Materials/BNDs Participation in Inter Laboratory Program Support to the Stake holders in our country Measurement Traceability through Dissemination of CRMs/BNDs Conducting Proficiency Testing program Establish Traceability of the Reference Material Producers CMC related to water Effort taken
3 Technical capability NPLI for trace elemental analysis Capabilities building of the personnel Scientists, supporting staff working have been trained under NPL-PTB Technical cooperation for MiC activity Undergone IDMS training at BAM, Berlin and NIM, Thailand
4 Work ne so far. Quality management system (ISO/IEC17025:2005) Implemented November 2011 International Peer-review on Aqueous elemental activity February 2012 by the technical expert from BAM Germany Balances Calibrated Mass Prototype 57
5 Development of CRMs Mandate - Development of Indigenous Certified Reference Materials (Bharatiya Nirdeshak Dravyas ) to improve the quality of life in India by Dissemination of Measurement Traceability to the end product CRM related to Aqueous Elemental Standard Solution Preparation, certification of reference materials and its dissemination (Trade Mark No , Registered
