Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of

ISO 17664:2017(E)
Introduction
This document applies to manufacturers of those medical devices that are intended to be processed by
the user or a third party to be made ready for use. This includes
— medical devices that are intended for reuse and require processing to take them from their state
after clinical use to the state of being cleaned, disinfected and/or sterilized and ready for their next
use, and
— single-use medical devices that are supplied non-sterile but are intended to be used in a clean,
disinfected and/or sterile state and therefore will require processing prior to use.
Significant advances in technology and knowledge have resulted in the development of complex medical
devices to support the delivery of healthcare to patients. These advances have led to medical devices
being designed that are potentially more difficult to clean, disinfect and/or sterilize.
Cleaning, disinfecting and sterilizing technologies have also undergone significant change in the past
decade, resulting in new systems and approaches that can be applied in the processing of medical
devices. This has led to a greater appreciation of the need for validation of processing including cleaning,
disinfection and/or sterilization in order to ensure that medical devices are effectively processed.
These developments have led to the need to ensure that manufacturers of reusable medical devices
provide adequate instructions that support the end users to undertake safe and effective processing of
medical devices, utilizing the available equipment and processes.
A medical device requiring processing is supplied with detailed processing instructions in order to
ensure that, when followed correctly, the risks of transmission of infectious agents are minimized. In
addition, effective processing minimizes the risk of other adverse effects on medical devices.
Cleaning is an important step in rendering a used medical device safe for reuse. Failure to remove
contaminants (e.g. blood, tissues, microorganisms, cleaning agents and lubricants) from both the
inside and outside surfaces of medical devices could compromise any subsequent disinfection
and/or sterilization process or the correct functioning of the medical device. Single-use medical devices
provided by the medical device manufacturer for processing prior to use can also require cleaning prior
to further processing.
After cleaning, other factors can affect the safe and effective use of a medical device. For example,
procedures for inspection and functional testing might be necessary to ensure that a medical device
does not pose a safety risk when used. Manufacturers of medical devices can assist users by providing
instructions on how this inspection and testing should be performed.
Manufacturers of medical devices that are to be processed have a responsibility to ensure that the
design of the medical devices facilitates achievement of effective processing. This includes consideration
of commonly available validated processes; examples are shown in Annex A. This annex can be used as
a guide to validate procedures.

1 Scope
This document specifies requirements for the information to be provided by the medical device
manufacturer for the processing of a medical device that requires cleaning followed by disinfection
and/or sterilization to ensure that the device is safe and effective for its intended use.
This includes information for processing prior to use or reuse of the medical device. The provisions
of this document are applicable to medical devices that are intended for invasive or other direct or
indirect patient contact.
Processing instructions are not defined in this document. Rather, this document specifies requirements
to assist manufacturers of medical devices in providing detailed processing instructions that consist of
the following activities, where applicable:
a) initial treatment at the point of use;
b) preparation before cleaning;
c) cleaning;
d) disinfection;
e) drying;
f) inspection and maintenance;
g) packaging;
h) sterilization;
i) storage;
j) transportation.
This document excludes processing of the following:
— non-critical medical devices not intended for direct patient contact;
— textile devices used in patient draping systems or surgical clothing;
— medical devices specified by the manufacturer for single-use only and supplied ready for use.

NOTE 2 National authorities can allow or require the use of an alternative process. In such cases they usually
require validation of those processes by the processor.
4.3 If a manufacturer supplies a number of different medical devices that share common attributes,
then validation studies may be performed as a product family. If this approach is taken, the medical device
manufacturer shall demonstrate commonality between the different medical devices and the validation

6.6.2.1 If the automated cleaning process recommends the use of a washer-disinfector meeting the
requirements of the ISO 15883 series, the information regarding the automated process may be limited to
those parameters that are specific for the medical device, such as specific load configuration, positioning,
connection, accessories, process chemicals, pressures or temperature limit(s) and a statement confirming
the recommendation to use a washer-disinfector complying with the ISO 15883 series.
ISO 17664:2017(E)
6.6.2.2 If the specific cleaning requirements of the medical device do not allow a generic claim of
compatibility with a washer-disinfector meeting the requirements of the ISO 15883 series, then the
following information shall be included, where applicable:
