Visszamérési

Visszamérési is a Hungarian term used in metrology, quality assurance and related fields to denote the act of performing a measurement after an initial measurement with the aim of verification, calibration, or uncertainty assessment. The word is formed from vissza ('back' or 'again') and mérés ('measurement'), with the adjectival suffix -i to yield visszamérési.

A visszamérés is typically planned within a measurement campaign to confirm the accuracy and reliability of results, to detect instrument drift, to verify traceability to recognized standards, or to support calibration cycles. It may involve using the same instrument under similar conditions or employing a calibrated reference instrument. The data from the initial and subsequent measurements are compared, and differences are analyzed to estimate measurement uncertainty, identify potential systematic errors, and decide whether corrective action is required.

Relation to other concepts: Visszamérési is related to repeatability and reproducibility studies, calibration procedures, and validation processes. It is distinct from a casual retake, as it is usually formalized within quality management or metrological frameworks and documented to support traceability and quality assurance. In practice, the term appears in Hungarian normative documents and technical reports describing measurement workflows and calibration regimes.
