Sterilization is a cornerstone of modern healthcare, ensuring that medical devices used in patient care are free from harmful microorganisms. Among the various sterilization methodologies, industrial steam sterilization is distinguished for its efficacy and dependability. The recent publication of ISO 17665:2024 represents a pivotal development in this process. As experts in the industry, we’ll delve into the evolution, significance, and future of this standard, providing our perspective on its critical components.


ISO 17665:2024: A Comprehensive Guide


ISO 17665:2024 provides a framework for steam sterilization processes. This standard articulates rigorous requirements for the validation, control, and monitoring of the sterilization process. Its importance lies in its role in maintaining the sterility of medical devices, thereby mitigating infection risks, and ensuring patient safety.


Core Components of ISO 17665


ISO 17665 outlines stringent requirements for steam sterilization processes to ensure the safety and effectiveness of medical devices, including:


  • Process Validation: Ensuring that the sterilization process is capable of consistently producing sterile devices.
  • Control and Monitoring: Implementing robust controls and monitoring mechanisms to maintain process parameters within specified limits.
  • Microbiological Inactivity: Emphasizing the importance of effectively inactivating microbiological contaminants to prevent infections.
  • Patient Safety: Reinforcing the integral role of sterilization in safeguarding patient health and ensuring the reliability of medical devices.


What has changed in the newest version (ISO 17665:2024)?


ISO 17665:2024 synthesizes and supersedes three antecedent documents, which have been withdrawn:

  1. ISO 17665:-1:2006 Part 1:
    • Established foundational requirements for the development, validation, and routine control of sterilization processes for medical devices.
    • Its principles have been integrated and expanded in the current standard.
  2. ISO/TS 17665-2:2009 Part 2:
    • Provided interpretative guidance on the application of ANSI/AAMI/ISO 17665-1.
    • Facilitated practical implementation of the requirements by manufacturers.
  3. ISO/TS 17665-3:2013 Part 3:
    • Offered guidance on categorizing medical devices into product families and processing categories for steam sterilization.
    • Streamlined the process of device categorization to optimize sterilization protocols.


Anticipating the Future: Development of WD TIR116


In the ongoing effort to enhance sterilization processes, the development of WD TIR116 is a significant step forward. This new document aims to provide comprehensive guidance on establishing product families for steam sterilization based on attributes such as materials, packaging, and complexity. By facilitating the justification of product groupings, WD TIR116 will allow users to reduce cost and time needed to validate their product.




Sterilization standards such as ISO 17665:2024 are indispensable for ensuring safety of medical devices. The newest version of the standard supersedes legacy documents and provides clarity on sterilization requirements for medical device manufacturers. The impending WD TIR116 will help users understand how to establish product families based on materials, design complexity, and interaction with the packaging system.
