Disagreement between an examined value and a reference nominal property value.
Examples: - The reference nominal property value is "red" and the examined value is "pink". Narrative expression: The examined value disagrees with the reference nominal property value, so that an examination error is present.
- The reference nominal property value is "BCD" and the examined value is "BCD". Narrative expression: The examined value agrees with the reference nominal property value, so there is no examination error.
Notes: - An examination error is either present or absent.
- Examination error is associated with an examined value, but not with an examining system.
- Examination error should not be confused with production error or mistake.
