What does a calibration overdue list indicate?

A calibration overdue list serves as an important tool within a quality management system. It specifically identifies devices that are past their scheduled due date for calibration. This is crucial because calibration ensures that measurement instruments meet specific standards of accuracy and precision. When devices are overdue for calibration, it indicates that they have not been verified against these standards and could potentially provide inaccurate measurements.

Identifying these devices allows organizations to prioritize their calibration efforts, ensuring that all equipment remains compliant with regulatory requirements and internal quality standards. This proactive approach helps maintain the integrity of processes and products, avoiding potential issues caused by uncalibrated instruments.

While routine maintenance may involve checking equipment for performance and wear, it is not the focus of a calibration overdue list; the main concern is verifying measurement accuracy through calibration. Similarly, devices functioning properly would not generally be listed as overdue, nor does this list imply that devices need immediate replacement. In essence, an overdue list is a notification system to ensure timely adherence to calibration schedules.
