Calibration Extended Labels

A calibration date might be extended if historical data shows the device has very low drift, if the equipment is used infrequently, or if a risk assessment determines the extension will not compromise quality. It is a formal, documented decision, as opposed to a simple calibration not required status.

These labels must include the "New Due Date" for the calibration. They also typically have fields for the "Extended By" (authorizing person's initials) and the "Date" the extension was granted, ensuring full traceability for the decision.

Only authorized quality assurance personnel or a calibration technician should apply this label. It is not a decision an everyday operator can make; it must be a controlled action within the company's quality management system.

While not done universally, extending calibration periods is a common practice in mature quality systems. It is a data-driven approach to optimize calibration frequency, saving costs on unnecessary calibrations while still ensuring measurement accuracy.
