kalibraatioketju
Kalibraatioketju refers to the traceable sequence of comparisons between a measurement instrument and a known standard. Each step in this sequence involves a calibration process where the instrument's readings are compared to a reference. This reference is itself calibrated against a higher-level standard, and so on, creating a chain of traceability. The ultimate link in this chain is usually a national or international primary standard, maintained by a metrology institute.
The purpose of a kalibraatioketju is to ensure that measurements made by any instrument can be related
The integrity of the kalibraatioketju depends on the competence of the calibration laboratories involved and the
