kalibrerað

Kalibrerað is the Icelandic adjective used to describe an instrument or measurement result that has been calibrated against a reference standard to determine its accuracy. It is commonly used in science, industry, medicine and commerce to indicate that a device’s measurements can be traced to recognized standards.

Calibration involves comparing readings from the instrument to a known standard under defined conditions. If the instrument drifts, adjustments may be made to bring readings into alignment; if not adjustable, the deviation is recorded and applied as a correction factor in subsequent measurements. The process also involves documenting measurement uncertainty and the conditions under which the calibration was performed.

A calibration certificate is typically issued for a kalibrerað instrument. It includes identifiers for the instrument, the date of calibration, the next due date, the reference standards used, the reported measurement uncertainty, and the method or procedure followed. This documentation provides traceability to national or international standards.

Traceability is a core concept in calibration. Calibrations are linked to higher-level standards through a chain of comparisons that ultimately reaches SI units. Laboratories performing calibrations often operate under recognized quality systems, such as ISO/IEC 17025, and maintain control over environmental conditions and equipment.

Applications of kalibrerað span many fields. Common examples include thermometers, balances, pressure gauges, electrical measuring instruments, optical devices, and various medical and laboratory instruments. Regular calibration helps ensure measurement reliability, quality control, compliance with regulations, and informed decision-making across industries.
