Metrological traceability
The property of a result whereby it can be related to a stated reference — usually the SI — through a documented unbroken chain of calibrations, each contributing to the uncertainty.

Calibration
The operation that, under specified conditions, first establishes a relation between values (with uncertainties) provided by measurement standards and corresponding indications (with uncertainties), and second uses that information to obtain results from indications. Calibration is not adjustment.

Metrological traceability chain
The sequence of standards and calibrations used to relate a result to a stated reference — the concrete path behind a traceability claim.

Metrological comparability of measurement results
Comparability of results traceable to the same reference — what shared traceability buys: results that can be meaningfully compared even from different labs and methods.

Verification
Provision of objective evidence that a given item fulfils specified requirements — e.g. that an instrument performs within its maximum permissible errors. A pass/fail attestation, distinct from calibration.
