Full title and description

ISO 17665:2024 — Sterilization of health care products — Moist heat — Requirements for the development, validation and routine control of a sterilization process for medical devices. This International Standard defines requirements and accompanying guidance for establishing, validating, monitoring and documenting moist heat (steam) sterilization processes used to render medical devices sterile for safe clinical use.

Abstract

This standard provides normative requirements and informative guidance covering cycle development, equipment qualification, biological and physical process monitoring, load configuration, routine process control, acceptance criteria and documentation necessary to ensure consistent moist heat sterilization of medical devices. It consolidates and replaces earlier parts and technical specifications related to moist heat sterilization to provide a single, comprehensive document for manufacturers, sterilization service providers and healthcare facilities.

General information

• Number of pages: 154 pages (PDF/print edition as published by ISO).

Scope

Applies to the development, validation and routine control of moist heat (steam) sterilization processes for medical devices, including guidance on process design, load specification and arrangement, physical and biological monitoring, equipment qualification (IQ/OQ/PQ), process challenge devices, acceptance criteria and ongoing routine control. The standard is intended for use in industrial manufacturing, contract sterilization services and healthcare facility sterilization operations and replaces earlier part‑based and technical specification documents on moist heat sterilization.

Key topics and requirements

• Requirements for development and qualification of sterilization cycles (cycle design and load characterisation).
• Equipment installation, operational and performance qualification (IQ, OQ, PQ) for steam sterilizers.
• Physical monitoring requirements (temperature, pressure, time, measurement system calibration and traceability).
• Biological indicators and chemical indicators: selection, placement, interpretation and use for validation and routine control.
• Process challenge devices, load configuration and worst‑case load determination.
• Acceptance criteria, sterility assurance considerations and nonconforming product handling.
• Requirements for routine process control, record keeping and ongoing verification/maintenance.
• Guidance on risk management, statistical methods for validation and transfer of validated cycles between sites or equipment.

Typical use and users

Primary users include medical device manufacturers, contract sterilization service providers, hospital central sterile services departments (CSSD), regulatory and compliance personnel, validation engineers, QA/QC laboratories and test houses. The standard is used to design and validate sterilization processes, to prepare validation protocols and reports, and to establish routine monitoring and control practices.

Related standards

Related and complementary standards include ISO 11135 (ethylene oxide sterilization), ISO 11137 (radiation sterilization), ISO 14644 series (cleanrooms), ISO 13485 (medical device quality management systems) and historical/replaced documents ISO 17665‑1:2006, ISO/TS 17665‑2:2009 and ISO/TS 17665‑3:2013. Users should consult applicable regulatory guidance in addition to these standards when implementing sterilization validation programs.

FAQ

Q: What is this standard?

A: ISO 17665:2024 is an international standard that sets requirements and provides guidance for the development, validation and routine control of moist heat (steam) sterilization processes for medical devices.

Q: What does it cover?

A: It covers cycle design and development, equipment qualification, physical and biological process monitoring, load configuration and worst‑case determination, acceptance criteria, documentation and routine process control for steam sterilization. The document includes both normative requirements and explanatory guidance.

Q: Who typically uses it?

A: Manufacturers of medical devices, contract sterilization providers, hospital sterile services, validation and QA/QC teams, regulatory compliance specialists and testing laboratories use the standard to ensure and demonstrate effective moist heat sterilization.

Q: Is it current or superseded?

A: ISO 17665:2024 is the current published standard (published March 2024) and supersedes earlier documents including ISO 17665‑1:2006, ISO/TS 17665‑2:2009 and ISO/TS 17665‑3:2013 which were withdrawn upon publication of the consolidated 2024 edition.

Q: Is it part of a series?

A: Historically ISO 17665 existed as a multipart set (parts and technical specifications). The 2024 publication consolidates those materials into a single International Standard; related sterilization standards (different modalities) form a broader family of sterilization standards (for example ISO 11135 and ISO 11137).

Q: What are the key keywords?

A: Moist heat, steam sterilization, validation, sterilizer qualification, biological indicators, process monitoring, medical devices, cycle development, sterility assurance.
