Are devices that are exempt from calibration clearly marked as such?
Are the reference devices (standard equipment) used for base-point calibrations (0 point, maker's scale, etc.) correctly stored, managed and calibrated to NIST standards?
Does the master standard for internal calibration have adequate capability (i.e. 10x higher resolution)
Is an appropriate method set up for storing measuring equipment, tools, and jigs?
Are measuring and test equipment re-calibrated when found not meeting the requirement?
Is there a process for the disposition or recall of product that has been built/tested with equipment found to be out of calibration?
Have the personnel in charge of calibration been trained and formally certified?
