Overview
EN 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 - specifies requirements and gives guidance for the development, validation and routine control of moist heat (steam) sterilization processes used on medical devices. The document combines normative requirements with explanatory guidance to promote good practice for moist heat sterilization in both industrial and health‑care settings. It replaces earlier editions (EN ISO 17665-1:2006 and CEN ISO/TS 17665-2:2009) and is endorsed by CEN.
Key topics and requirements
- Process development: requirements for designing a moist heat sterilization cycle appropriate to the device and load configuration.
- Process validation: requirements for establishing and documenting that a sterilization process consistently achieves the intended microbial reduction (including use of biological and chemical indicators and process challenge devices).
- Routine control and monitoring: requirements for ongoing control, routine testing and records to ensure continuing process performance.
- Guidance and good practice: explanatory guidance intended to clarify normative clauses and support practical implementation.
- Regulatory alignment: informative annexes (ZA and ZB) detail the relationship to EU Regulations (MDR 2017/745 and IVDR 2017/746), noting scope limits and how conforming to the standard can provide a presumption of conformity when cited in the Official Journal of the EU.
- Scope limits: the standard focuses on achieving microbial states via moist heat; aspects such as package design for maintenance of sterility during transport/storage or unrelated manufacturing activities are not covered.
Practical applications
- Developing and qualifying steam sterilization cycles for packaged medical devices and reusable instruments.
- Validating new sterilizer models, load configurations and process challenge devices.
- Establishing routine monitoring programs using biological and chemical indicators and documenting ongoing compliance.
- Supporting regulatory submissions and demonstrating compliance with EU MDR/IVDR when the standard is applied as part of a quality and validation program.
Who should use this standard
- Medical device manufacturers and contract sterilization service providers

Introduction
A sterile medical device is one that is free of viable microorganisms. International Standards that specify
requirements for validation and routine control of sterilization processes require when it is necessary to
supply a sterile medical device, that adventitious microbiological contamination of a medical device prior to
sterilization be minimized. Even so, medical devices produced under standard manufacturing conditions,
can, prior to sterilization, have microorganisms on them, albeit in low numbers. Such medical devices are
non-sterile. The purpose of sterilization is to inactivate the microbiological contaminants and thereby
transform the non-sterile medical devices into sterile ones.
The kinetics of inactivation of a pure culture of microorganisms by physical and/or chemical agents used
to sterilize medical devices generally can best be described by an exponential relationship between the
number of microorganisms surviving and the extent of treatment with the sterilizing agent; inevitably this
means that there is always a finite probability that a microorganism can survive regardless of the extent
of treatment applied. For a given treatment, the probability of survival is determined by the number and
resistance of microorganisms and by the environment in which the organisms exist during treatment. It
follows that the sterility of any one product in a population subjected to sterilization processing cannot be
ensured and the expression of sterility of a processed population is defined in terms of the probability of
there being a viable microorganism present on a product item.
The process variables for a moist heat sterilization process, i.e. those which contribute towards microbial
lethality, are exposure to adequate temperature for a prerequisite time in the presence of moisture. Moist
heat sterilization can be utilised as a saturated steam process, where saturated steam is allowed to directly
contact all surfaces to be sterilized, or as a contained product sterilization process, where steam, steam
mixed with air or other gas, or hot water under pressure are used as the heating medium in order to generate
moist heat within the sealed contained product. The term saturated steam describes a theoretical state
in which water and vapour are in equilibrium and that no other gases are present. In practice theoretical
saturated steam state conditions are not achieved. Mixtures of steam and NCGs, albeit in very low levels, will
be supplied to the sterilizer and employed as the sterilizing agent, moist heat.
This document describes requirements that, if met, will provide a moist heat sterilization process intended
to sterilize medical devices, which has appropriate microbicidal activity. Furthermore, conformance with
the requirements, ensures this activity is both reliable and reproducible so that predictions can be made,
with reasonable confidence, that there is a low level of probability of there being a viable microorganism
present on product after every sterilization process is complete. Specification of this probability is a matter
for regulatory authorities and can vary from country to country (see, for example, EN 556-1 and ANSI/
AAMI ST67).
Generic requirements of the quality management system for design and development, production,
installation and servicing are given in ISO 9001 and particular requirements for quality management
systems for medical device production are given in ISO 13485. The standards for quality management
systems recognise that, for certain processes used in manufacturing, the effectiveness of the process cannot
be fully verified by subsequent inspection and testing of the product. Sterilization is an example of such a
process. For this reason, sterilization processes are validated for use, the performance of the sterilization
process is monitored routinely, and the equipment is maintained.
Exposure to a properly validated, accurately controlled, monitored and recorded sterilization process is not
the only factor associated with the provision of reliable assurance that the product is sterile and, in this
regard, suitable for its intended use. Attention is therefore given to a number of factors including:
a) the microbiological status of either incoming raw materials or components, or both;
b) the validation and routine control of any cleaning and disinfection procedures used on the product;
c) the control of the environment in which the product is manufactured, assembled and packaged;
d) the control of equipment and processes;
e) the control of personnel and their hygiene;
vi
ISO 17665:2024(en)
f) the manner and materials in which the product is packaged;
g) the conditions under which product is stored.
The type of contamination on a product to be sterilized varies and this has an impact upon the effectiveness
of a sterilization process. It is preferable that products that have been used in a health care setting and
that are being presented for sterilization in accordance with the instructions for use (see ISO 17664-1) be
regarded as special cases. There is the potential for such products to possess a wide range of contaminating
microorganisms (bioburden) and either residual inorganic or organic contamination, or both, in spite of the
application of a cleaning process. Hence, particular attention is given to the validation and control of the
cleaning and disinfection processes used during processing. The ISO 15883 series provides requirements
for and information on automated cleaning and disinfection processes.
This document describes the requirements for ensuring that the activities associated with the process
of moist heat sterilization are performed properly. The requirements are the normative parts of this
