AS9100 D

Airplane, aerospace, AS9100


Section of AS9100D States that “the organization shall establish, implement, and maintain a process for the recall of monitoring and measuring equipment requiring calibration or verification.”

Are calibration and verification both referring to the checking of equipment to make sure that it is suitable for it’s purpose, or is verification referring to the measurements taken on product? More specifically, does this require the organization to be able to identify which piece of measurement equipment made which measurements? In other words, if I have two micrometers that are both in a system that recalls them periodically for calibration, have I satisfied the requirements of even if I don’t record which micrometer makes which measurements during it’s daily use?


The calibration or verification both refer to the monitoring and measurement equipment.  The AS9100D additional text is consistent with the ISO 9001:2015 by referring to calibration or verification.  The monitoring and measurement equipment could require verification as meeting requirements instead of a calibration.  If monitoring and measurement equipment is found to be out-of-tolerance and there is a product conformity impact, then it is very helpful if the organization has identified which instrument was used for which job.  Otherwise, the recall of product or alerting customers is much broader since the impact is not understood.  There is not specifically an AS9100D requirement to record which monitoring and measuring equipment was used but it is a good practice.
