During our recent surveillance audit, we were given a nonconformance "the laboratory scope does not include equipment calibrated in the plant". We do have a lab scope which includes equipment in our test lab facility, which has been accepted. IMTE in the production units (x-ray gaging, micrometers, calipers, etc.) is under calibration and listed in each areas master list. Calibration occurs at the equipment or within the area of use (taken to an office in the area and calibrated). Does a lab scope really apply here?
