Understanding ISO 13485: Ensuring Quality in Medical Devices
Summary of ISO 13485 Content
Starting on February 2, 2026, most medical device companies who sell their devices in the United States must comply with FDA’s new Quality Management System Regulation (QMSR, 21 CFR 820), which on that day will replace the current Quality System Regulation (QSR, 21 CFR 820). In addition, from February 2 forward, medical device organizations must comply with ISO 13485 – Medical devices – Quality management systems.
Nearly all the content in the current QSR (14 Subparts, A – O) the ISO standard’s framework of eight clauses will be incorporated by reference into the quality system standard. However, some QSR content (regulations and definitions) will remain in the new QMSR regulation to ensure continued regulatory alignment with the Food, Drug, and Cosmetic Act (FD&C Act). This includes some of the current regulations and definitions related to Document Controls, Labeling and Packaging Control, Records, and Servicing.
And as mentioned, in addition to the shortened FDA portion of the QMSR medical device organizations will be required to be in compliance with the quality management standard As an overview of the standard, the following are titles and content descriptions for ISO 13485’s clauses.
Clause 1: Scope
This clause outlines the standard’s applicability, focusing on medical devices and related services to consistently meet customer and regulatory requirements. It highlights the flexibility for organizations to exclude certain design or manufacturing requirements if not applicable, provided such exclusions do not compromise compliance.
Clause 2: Normative References
ISO 13485 has no normative references, meaning no additional documents are essential for its application. It is a standalone standard but is closely aligned with ISO 9001 and regulatory requirements for medical devices.
Clause 3: Terms and Definitions
This clause refers to the definitions provided in ISO 9000:2015, with additional terms specific to medical devices. It ensures consistent interpretation of key concepts, such as “risk,” “product,” and “medical device.”
Clause 4: Quality Management System
Organizations must establish, document, and maintain an effective quality management system (QMS). This includes identifying processes, determining interdependencies, managing outsourced processes, and documenting the QMS through procedures, manuals, and records.
Clause 5: Management Responsibility
Top management is responsible for QMS effectiveness. This clause emphasizes the need for quality policies, measurable objectives, management reviews, and ensuring resources and customer-focused communication are available to meet compliance and quality goals.
Clause 6: Resource Management
This clause focuses on allocating sufficient resources, including personnel, infrastructure, and the work environment, to maintain the QMS. It includes requirements for competence, training, awareness, and proper facilities to ensure safe and effective product realization.
Clause 7: Product Realization
This extensive clause covers planning and controls for product development, customer-related processes, design and development, purchasing, production, and service provision. It emphasizes risk management, traceability, and validation of processes critical to ensuring product safety and quality.
Clause 8: Measurement, Analysis, and Improvement
Organizations must establish processes to monitor, measure, and analyze product conformity, process performance, and customer satisfaction. This clause includes requirements for internal audits, nonconformity management, corrective actions, preventive actions, and data analysis to drive continual improvement.
