Definition
Realization of the definition of a given nominal property (2.1), with stated nominal property value (3.1) and associated examination uncertainty (3.9), used as a reference.

Note
A "realization of the definition of a given nominal property" can be provided by an examining system or a nominal reference material.

Example
A given examined value for a bacterial taxon can be compared for equivalence with the stated nominal property value of an examination standard in the form of typical bacteria of the species.
