According to our customer requirement, our quality inspectors are signing each step in production rough card in the following way: they apply their personal stamp (which includes their first and last name and personal number), add a manual signature and date. I tried to convince our customer to give us permission to eliminate the manual signature (as the personal stamp and date are enough), but he doesn’t agree with me.
Is there any official standard for this procedure? I was not able to find any special requirement for this in AS9100 Rev. C – Requirements for Aviation, Space and Defense Organizations.
The AS9100 standard does not dictate any specific method of recording that a production step (clause 7.5.1) or verification step (clause 8.2.4) is complete. AS9100 does require the organization to comply with customer requirements. So this is a requirement which you need to discuss with your customer.
