Re: Should Serial # of all Measurement Instruments (Calipers,etc) be in Control Plans
We had a similar case, in control sheet, QC person was signed and stamped, and measurement method stated (digital caliper or something).
So auditor said we need to state s/n of the caliper on the control sheet.
I argued that it was absurd, as we have complete database of measurement equipment and list showing who was using what from when to when, so all is traceable and certified, and we really don't need to know what gage was used for what measurement...
In my oppinion, traceability is far more important then stating all information everywhere.
All the papers regarding gages, people, control methods or statistics can be easily and quickly found in QC headquarters
