Calculation of measurement uncertainty

Calculation of measurement uncertainty is the basis of measurements, tests in calibration laboratories, tests and their calibration, tests reports. Calculation of measurement uncertainty is one of the basic requirements of the international standard ISO/IEC 17025 General requirements for the competence of testing and calibration laboratories, on the metrological traceability of measurements. Calculation of measurement uncertainty has a direct impact on the development of trade and technology, the production and marketing of certain products in the measurement chain with a high degree of accuracy. The measurement uncertainty is calculated and defined as a value, accompanied by the result of a measurement, a test that is characterized by the distribution of values that can reasonably describe a measurement
