What is measurement uncertainty in calibration?
Measurement uncertainty in calibration refers to the range within which the true value of a measurement is expected to lie. It indicates the level of confidence in the accuracy of an instrument after calibration and helps users understand how precise the measurement results are.
For example, if a pressure gauge shows 10 bar with a measurement uncertainty of ±0.1 bar, the actual pressure may lie between 9.9 bar and 10.1 bar. This helps organizations assess whether the instrument is suitable for critical applications.
In India, measurement uncertainty is calculated and reported as part of calibration activities in accordance with guidelines from the National Accreditation Board for Testing and Calibration Laboratories (NABL) and international standards such as ISO/IEC 17025.
