kalibreringsgynnor

Kalibreringsgynnor are small, typically metallic, objects used in the calibration of measuring instruments. The term itself is a compound of "kalibrering" (calibration) and "gynnor" (a Swedish word for weights or counterbalances, though in this context it refers more broadly to reference standards). These gynnor are manufactured to extremely precise specifications, often with very low tolerances for mass, dimension, or other relevant properties.

The purpose of kalibreringsgynnor is to provide a known, reliable standard against which an instrument can be compared. For example, a weight calibration gynna would be used to verify the accuracy of a scale or balance. A dimensional calibration gynna might be used to check the precision of calipers or micrometers. The accuracy of the gynna itself is traceable to national or international standards, ensuring that the calibration performed is internationally recognized and valid.

The materials used for kalibreringsgynnor vary depending on their intended application. Stainless steel, brass, and specialized alloys are common. For applications requiring extreme stability and resistance to environmental factors, materials like invar may be employed. Their design can range from simple, uniform shapes to more complex forms depending on the instrument being calibrated. Regular recalibration of the gynnor themselves is crucial to maintain the integrity of the calibration process.
