Good call by the auditor. Probably knew that a micrometer would not be a good gage to measure to a .00005 tolerance, and found one supporting piece of evidence for the point. Gage R&R should also show a very dubious ndc for using that gage at that tolerance.
Wait a minute! Is the micrometer actually used in service to measure dimensions with the smaller tolerance? If the dimensions it is used to measure fall within the calibrated tolerance, where is the violation?

Yes, it is used in service for smaller dimensions only.

Good point, if the "tolerance" specified on the NC is what they are trying to measure on the part, then the gage is useless. If the tolerance is the gage tolerance, then there really is no basis for complaint (it just looks like a standard gage spec, see this) - the NC needs to identify the relationship to the part tolerance to be of an issue.
Thanks to bobdoering for your informative Post and/or Attachment!
