There is an ASME standard for calipers- ASME B89.1.14-2018 as well. If you need a procedure, I'd be happy to send you ours if you need it. Message me.
Found Mitutoyo's guidance(s) for calibration, and loosely wrote protocols to that (referenced ASME B89.1.14); essentially 3-5 graduations measured across 90% of the equipment operational range. I added 3-5 measurements at each graduation in an effort to address R&R of devices in parallel. i would appreciate any information you'd be willing to share... especially any help with propagation of error/measurement uncertainty determination and reporting?
