referensmåttstocks

A referensmåttstock, which translates to "reference ruler" or "calibration ruler" in English, is a specialized measuring instrument used in various fields, primarily for calibration and quality control purposes. Unlike a standard ruler used for general measurements, a referensmåttstock is manufactured to extremely high precision, with its markings and overall length verified against national or international standards.

These rulers are often made from materials with very low thermal expansion coefficients, such as Invar or specialized glass, to minimize errors caused by temperature fluctuations. The scale markings on a referensmåttstock are typically etched or engraved rather than printed, ensuring durability and accuracy over time. The spacing between these markings is meticulously controlled and certified.

The primary function of a referensmåttstock is to serve as a known, accurate standard. It is used to calibrate other measuring instruments, such as calipers, micrometers, coordinate measuring machines (CMMs), and even less precise rulers. By comparing the readings of an instrument against the certified values of the referensmåttstock, its accuracy can be determined and, if necessary, adjusted.

In industries where precision is paramount, such as manufacturing, metrology, aerospace, and scientific research, referensmåttstocks are essential tools. They play a critical role in ensuring that manufactured parts meet tight tolerances, that experimental results are reliable, and that overall product quality is maintained. Regular calibration of the referensmåttstock itself is also a crucial part of the metrological process.
