Calibration hierarchy
The sequence of calibrations from a stated reference to the final measuring system, each calibration depending on the previous one; uncertainty necessarily grows down the chain.

Metrological traceability to a measurement unit
Traceability whose stated reference is the definition of a unit through its practical realization — "traceable to the SI" in its precise sense.

Calibration curve
The expression of the relation between indication and corresponding measured quantity value established by calibration — the diagram's central line, without the uncertainty strip.

Calibration interval
The period between successive calibrations of an instrument, set and adjusted from stability history, usage, environment, and risk — commonly managed with interval-analysis methods such as those in NCSLI RP-1 and ILAC-G24.

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.
