Specs: What are the effects on accuracy due to possible deterioration within calibration periods?

The measurement uncertainty will increase as the instrument deteriorates within the calibration period. However, this would not be apparent until the instrument is calibrated. This would make it necessary to review manufacturing records to track down any potentially out-of-tolerance products, then shorten the calibration interval.
