Metrological traceability
A core concept in metrology is metrological traceability, defined by the BIPMas «the property of the result of a measurement or the value of a st andard whereby it can be related to stated references, usually national or international standards, through an unbroken chain of comparisons, all having stated uncertainties)). The level of traceability establishes the level of comparability of the measurement: whether the result of a measurement can be compared to the previous one, a measurement result a year ago, or to the result of a measurement performed anywhere else in the world.
