Calibration Management System Auditing

Service summary

An assessment of how measuring equipment is identified, maintained and controlled for its intended use. The audit examines calibration or verification arrangements and the response to equipment found outside acceptance limits.

The service supports confidence in measurement management through documented findings. It does not perform calibration, issue calibration certificates or independently establish measurement accuracy for individual instruments.

Key objectives

• Assess measurement equipment control
• Examine calibration and traceability evidence
• Evaluate suitability and acceptance decisions
• Review out-of-tolerance impact handling

Methodology

Selected instruments are traced from intended use through calibration status, certificate review and any associated product-impact decisions.

• Define equipment groups, measurement uses and audit criteria.
• Review equipment registers, intervals and acceptance requirements.
• Select critical instruments, overdue items and out-of-tolerance cases.
• Observe identification, protection and calibration-status controls.
• Examine certificates, traceability evidence and technical review records.
• Assess impact evaluations and actions following unacceptable results.
• Report measurement management findings without issuing calibration results.
