That is my irony.
We are AS9100 Certified, oue Aerospace customers require us to use only ISO or AS cerified calibration labs.
There isn't a catagory in Nadcap for calibration certification, but I can strech the rules a little, and approve a Nadcap welding certification instead of ISO or AS.
From what I see, Nadcap leaves it up to your QMS to determine who can calibrate your machines.
