Definition
Fraction of examined values identical to one or more reference nominal property values among all the examined values provided.

Notes
1) Each examined value is either equivalent, or non-equivalent, to the reference nominal property value.
2) The examination trueness, in contrast to measurement trueness, is a quantity, and is complementary to examination uncertainty.

Example
The reference nominal property value is "B". The nominal property value set of all possible values is {A, B}. For nine of 10 examinations the examined value is "B". The examination trueness is therefore 0.9 (\(\pu{90\%}\)).
