    Q3. Is calibration laboratory of NCB accredited?

    Ans. It is accredited by NABL for calibration of equipment in mechanical and thermal field. A large number of areas: force, pressure, dimension, revolution,. Temperature and RH are covered.

    Q4. What is the use of certified reference materials (CRMs)?

    Ans. Certified Reference Materials are used for the calibration of equipment, preparation of standard solutions, validation of a test procedure and checking proficiency of a chemist/operator. NCB is the sole provider of CRMS for cement and construction materials sector. Many of these CRMS are mandatory for calibration of equipment under BIS scheme of testing and inspection (STI) for cement industry.

    Q5. What is uncertainty of measurement?

    Ans. It is a parameter associated with the result of measurement that characterizes the dispersion of the true values which could reasonably be attributed to the measurand.
