Reviewed by [Christian Espinosa, Founder, Blue Goat Cyber](/authors/christian-espinosa) Last reviewed May 5, 2026 ## Definition The ISO 11137 series (Parts 1, 2, 3) specifies requirements and guidance for development, validation, and routine control of gamma, X-ray, and electron beam [sterilization](/terms/sterilization) processes. What the regulation says The ISO 11137 series, encompassing Parts 1, 2, and 3, provides a framework for ensuring the sterility of medical devices using radiation. Regulators like the FDA often reference such international standards in their guidance and expectations for manufacturers, aligning with principles found in 21 CFR Part 820, [Quality System Regulation](/terms/qsr), regarding [process validation](/terms/process-validation). Adherence to ISO 11137 demonstrates a robust approach to [sterilization](/terms/sterilization) process control, a critical aspect of medical device safety and efficacy, as emphasized in EU [MDR](/terms/mdr-reporting) Annex I, [General Safety and Performance Requirements](/terms/gspr). ## What this means in practice Demand for non-EO [sterilization](/terms/sterilization) is growing; many manufacturers now maintain dual capability and qualify both routes. ## Examples - A manufacturer of sterile surgical kits uses ISO 11137-1 to establish the overall requirements for their gamma sterilization process, ensuring appropriate dose selection and validation methods. - A company developing a new implantable device follows ISO 11137-2 for performing dose establishment studies, determining the minimum required radiation dose to achieve sterility. - A quality control team routinely monitors the radiation dose delivered to each product batch and records environmental parameters in accordance with ISO 11137-3, ensuring ongoing process control. Common pitfalls - • Misinterpreting the dose necessary for different product types or bioburden levels can lead to ineffective sterilization or material degradation. - • Failing to re-validate sterilization processes after significant changes to the product, packaging, or manufacturing site can compromise sterility assurance. - • Inadequate documentation of the validation studies and routine monitoring procedures can result in regulatory non-compliance. - • Assuming a universal sterilization dose for all devices without conducting product-specific validation studies is a common error. - • Neglecting to consider the potential impact of radiation on material properties and device functionality can lead to product failures. ## Frequently asked questions What is the primary purpose of the ISO 11137 standard? The primary purpose is to establish requirements for the development, validation, and routine control of radiation [sterilization](/terms/sterilization) processes, specifically using gamma, X-ray, and electron beam methods, to ensure the sterility of medical devices. Which types of radiation sterilization does ISO 11137 cover? Why is validation crucial under ISO 11137? How does ISO 11137 relate to regulatory compliance for medical devices? ## Related terms Grouped by theme ### Editor's picks · Hand-selected related concepts [ Standards ISO 11135 Standard for development, validation, and routine control of ethylene oxide (EO) sterilization. ](/terms/iso-11135)[ Manufacturing Sterilization Validated process used to render a device free from viable microorganisms. ](/terms/sterilization) ### More in Standards · Same category [ Standards ASTM F2503 Standard practice for marking medical devices and other items for safety in the magnetic resonance environment. ](/terms/astm-f2503)[ Standards Essential Performance Performance of a clinical function whose loss or degradation would result in unacceptable risk. ](/terms/essential-performance)[ Standards ICH E6(R3) Good Clinical Practice(E6(R3)) Revision 3 of the ICH Good Clinical Practice guideline, restructured around principles, modernized for risk-based and decentralized trials, finalized in 2023. ](/terms/ich-e6-r3)[ Standards IEC 60601-1 General requirements for basic safety and essential performance of medical electrical equipment. ](/terms/iec-60601-1) Cited by Where this term appears across MedTech Terms.
