How should tool calibration schedules be documented?

• A. Calibration intervals are not linked to identifiers.
• B. Intervals defined but not recorded.
• C. Calibration intervals should be defined, recorded, and linked to tool identifiers and standards.
• D. Only the date of last calibration is needed.

Answer: (C)

Calibration schedules must be traceable to each tool and reference the standard used. The key practice is to define how often a tool should be calibrated, record that interval, and link it to the tool’s unique identifier and to the relevant calibration standard. This creates a complete, auditable trail: you know which device the schedule applies to, what the due date is, and which standard or specification governs the calibration criteria. When the interval is tied to the tool ID and the standard, inspectors can verify that the correct criteria were applied and that the tool remains within specification. If you only have the last calibration date, you lose the projected due date and you can’t prove that the next calibration will occur on time. If the interval exists but isn’t recorded, there’s no concrete schedule to follow or reference during audits. If the interval is recorded but not linked to the tool identifier, you can’t determine which device that schedule protects. Linking all three elements—defined interval, recorded record, and association with both the tool identifier and the standard—delivers reliable, verifiable calibration management.
