During ISO 9001 certification audit we had discussion with audited organization. I want to know your opinions:
If serial number or ID code of measuring equipment hasn't been indicated in test or quality control reports, is it non-conformity based on ISO 9001 requirements?
If yes which clause and category of non conformity major, minor or only observation?
Note: there are 4 piece of same calibrated measuring equipment and 4 competent inspector which may use different equipment during inspection.
