A poster had asked some questions regarding in-house calibrations, and I inadvertantly deteled the post. Sorry!
Anyway, it was a pretty good question, so I figured it would build our BOK here at the Cove. I am going from memory, here, so I may have missed a few things here and there.

This particular facility performed in-house calibration using gauge blocks that are calibrated by an external source. There are several micrometers, calipers, etc. that are verified. Questions:
1. Do these instruments require a certificate of calibration?
2. What information is required on the certificate of calibrations?
2. Do the measurement uncertainties need to be listed?
If I remember correctly, the poster was nearing an external ISO 9001 audti, and was worried about getting an NCI for the calibration.
Your thougths and suggestions, please.

). You have an appropriate standard, a decent procedure, the right numbers... You have a calibration. I hope you know what I mean. I just want to suggest a middle ground, reasonable approach. Calibration (and CoC) is not something everyone can do, and not something too difficult for anybody. Make sense.
