Måttkontrollen

Måttkontrollen is a term used to describe the processes and practices involved in measuring and controlling dimensions, quantities, and other metrological quantities to ensure accuracy, reliability, and suitability for purpose. It encompasses the methods used to verify that instruments and measurement results are trustworthy within an organization’s quality system and external requirements.

Key components of måttkontrollen include calibration, verification, and adjustment of measuring equipment; establishing traceability to recognized national or international standards; and assessing measurement uncertainty. It also involves standardized measurement procedures, proper documentation, and periodic checks to maintain consistency. Environmental conditions such as temperature and humidity are often monitored because they can influence measurement results.

Methodologically, måttkontrollen uses calibration intervals based on risk and usage, gauge repeatability and reproducibility studies, and statistical approaches such as SPC (statistical process control) and measurement system analysis to monitor and improve measurement quality. A measurement plan defines what is measured, how it is measured, and the acceptance criteria. Records of calibrations, deviations, and corrective actions form an essential part of the process.

Applications and governance vary by industry but commonly appear in manufacturing, laboratories, and trade to ensure products meet specified tolerances and regulatory requirements. Practitioners include metrologists, calibration technicians, quality engineers, and machine operators. Standards bodies and accreditation organizations support måttkontrollen by certifying laboratories and providing frameworks such as ISO 9001, ISO/IEC 17025, and ISO 10012 to guide measurement management and ensure traceability of results.
