Fraction of examined values with examination error that in replicate examinations remains constant or varies in a predictable manner.
Example: The reference nominal property value is "B". The following number of examined values were obtained in one set of examinations: 8 times "B", 9 times "C", 8 times "D", 4 times "E". In another set the following values were obtained: 16 times "B", 9 times "C", and 4 times "E". Narrative expression: The systematic examination error is that "C" and "E" are found in replicate examinations and neither represents a reference nominal property value.
Notes:
- Systematic examination errors for examined values are quantities.
- The systematic examination error for examined values can be expressed for a set of examined values as examination bias.
- Systematic examination error is a feature of an examining system used with a specified examination procedure.
