Role of Indian Reference Materials for the Calibration of Sophisticated Instruments

Measurements play an important role in technical field, construction, engineering sectors and in day-to-day activities. The accurate and precise measurements are crucial for scientific and industrial fields. Accuracy and precision in measurements eliminate chaos and encourage novelties which would help to save valuable lives, time and resources. To get accurate and precise measurement, calibration of sophisticated instruments is mandatory. For calibration of these complicated instruments, Certified Reference Materials (CRMs) will help to identify the non-performance of instrument and using this, one can ensure to get accurate and precise data. National Physical Laboratory, India (NPLI) is maintaining the primary and secondary standards and realization of “National Standard” and distribution of measurement traceability to national accreditation bodies and industries. Bharatiya Nirdeshak Dravya (BND^®) division of NPLI is continuously working for the development of various Indian Reference Materials (IRMs) in different sectors. This unbroken chain of traceable measurements improves confidence level in the international trade. In present article, we are going to discuss about the role of BNDs for calibration of sophisticated instruments and quality assurance of products.
