Calibration Recall

Calibration recall is the systematic process that ensures instruments are recalibrated before their due dates. An effective recall system identifies instruments coming due within a specified lead time (typically 30-90 days), generates notifications to the responsible parties (instrument owners, department managers, calibration coordinators), and facilitates the logistics of getting instruments to the calibration lab and back to the user.

The recall process typically involves generating a recall report or list of upcoming calibrations, notifying the custodian or owner of each instrument, scheduling the calibration (internally or with an external provider), arranging pickup, shipment, or hand-delivery to the calibration lab, tracking the instrument through the calibration process, and returning the calibrated instrument to service.

For calibration management, an efficient recall process is essential for maintaining high on-time calibration rates. Key metrics include the on-time calibration rate (percentage of instruments calibrated before their due date), average days past due for late calibrations, and recall processing time. Common challenges include instruments in use during production runs that cannot be released, instruments at remote locations, long lead times at external calibration providers, and instruments in storage or not in active use. Calibration management software automates much of the recall process and provides visibility into the calibration pipeline.
