ISO 13485 Calibration Requirements
ISO 13485:2016 specifies quality management system requirements for organizations involved in the design, production, installation, and servicing of medical devices. Calibration management under ISO 13485 carries heightened significance because measurement errors can directly affect patient safety and device efficacy. The standard requires documented calibration procedures, validated software used in calibration, and complete traceability records retained for the lifetime of the medical device.
ISO 13485 Clause 7.6 requires that monitoring and measuring equipment be calibrated at defined intervals using traceable measurement standards. Unlike ISO 9001, ISO 13485 explicitly requires documented procedures for calibration activities and mandates that records be retained for at least the lifetime of the medical device or as specified by regulatory requirements. Software used in monitoring and measurement must be validated before initial use and revalidated after changes.
FDA inspectors and EU Notified Bodies scrutinize calibration records during medical device facility audits and design history file reviews. They verify that all equipment used to measure critical-to-quality characteristics is calibrated with appropriate traceability, that out-of-tolerance conditions trigger documented impact assessments, and that calibration software has been validated per 21 CFR Part 820 or EU MDR Annex I requirements. Calibration gaps can result in FDA Warning Letters or CE mark suspension.
CalibrationOS is designed with medical device regulatory requirements in mind, providing validated calibration workflows with electronic signatures compliant with 21 CFR Part 11. The platform enforces record retention policies aligned with device lifetime requirements and generates audit-ready documentation packages for FDA inspections and Notified Body assessments. Risk-based equipment classification ensures that instruments measuring critical device characteristics receive appropriate calibration rigor.
ISO 13485 requires calibration records to be retained for at least the lifetime of the medical device, which can span decades for implantable devices. Regulatory authorities such as FDA and EU Notified Bodies may specify additional retention periods. CalibrationOS provides configurable retention policies that ensure records are never purged prematurely.
Yes, ISO 13485 Clause 7.6 requires validation of software used in monitoring and measurement before initial use. CalibrationOS provides a validation package including IQ/OQ/PQ protocols, requirements traceability matrix, and test scripts that support customer validation activities per GAMP 5 guidelines.
FDA inspectors verify that calibration procedures are documented, intervals are justified and maintained, traceability chains are complete, and out-of-tolerance impact assessments are thorough. They also check that calibration software is validated and that electronic records meet 21 CFR Part 11 requirements for electronic signatures and audit trails.
When an instrument is found out of tolerance, CalibrationOS automatically identifies all medical devices inspected or tested with that instrument since its last passing calibration. The platform generates an impact assessment report linking affected device serial numbers, lot numbers, and distribution records to support CAPA investigations and potential field actions.
Yes, CalibrationOS addresses requirements from both ISO 13485 and FDA 21 CFR Part 820, which share similar calibration requirements. The platform provides a unified compliance framework that satisfies international and US regulatory expectations, reducing the burden of maintaining separate calibration systems for different markets.
CalibrationOS automates tracking, audit trails, and due date management to keep you ISO 13485-ready.
