Mérésmódszertan

Mérésmódszertan, often translated as measurement methodology or metrology, is the scientific study of measurement. It encompasses the practical application of measurement, the theory behind it, and the development of new measurement techniques. This field is crucial for ensuring the accuracy, reliability, and comparability of measurements across various disciplines, including science, engineering, industry, and commerce.

The core principles of mérésmódszertan involve defining what is being measured, selecting appropriate instruments and methods, calibrating these instruments to known standards, and evaluating the uncertainty associated with the measurement results. Uncertainty quantification is a fundamental aspect, as it provides a range within which the true value of the measured quantity is expected to lie.

Key areas within mérésmódszertan include the development of international standards, the establishment of traceability to national or international measurement standards, and the investigation of systematic and random errors. It also deals with the design of experiments, data analysis, and the reporting of measurement results in a clear and unambiguous manner. The goal is to achieve a high level of confidence in the data obtained, enabling informed decisions and scientific progress.
