A calibration is basically defined as an activity which performs and documents a comparison between a standard and a unit under test, under defined conditions and with the relevant measurement uncertainty. A traceable calibration in an accredited laboratory is the only way to guarantee complete metrological proof – as per factory, national or international standards, to comply with norms such as IATF 16949.

Traceable calibrations are performed by laboratories that are accredited for this purpose (to DIN EN ISO/IEC 17025). This is the globally recognized standard that defines the requirements for the competence of test and calibration laboratories.
