ISO 17664-2:2021(E)
Introduction

This document applies to manufacturers of non-critical medical devices that are intended to be cleaned

and/or disinfected by the processor to be made ready for use or reuse. 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 ready for their next use;

— single-use medical devices that require processing before use and are intended to be used in a clean

and/or disinfected state.

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 and/or disinfect.

Cleaning and disinfecting 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 and/

or disinfection in order to ensure that medical devices are effectively processed. These developments

have led to the need to ensure that manufacturers of 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 subsequent use. Failure to

remove contaminants (e.g. blood, tissues, microorganisms, cleaning agents and lubricants) from

surfaces of medical devices could compromise the correct functioning of the medical device, its safe

use and (if required) any subsequent disinfection process. 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 risk to safety 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.

device shall conform with ISO 14971.

NOTE 1 Some of the points relevant to processing that any risk analysis can require (but not limited to)

include:

— the likely points of contact with the user and/or the patient that might allow cross-contamination;

— nature and design of the medical device;
— nature of the contamination on the medical device;
4 © ISO 2021 – All rights reserved
---------------------- Page: 9 ----------------------
ISO 17664-2:2021(E)
— intended use;
— foreseeable user error and misuse;
— user training;
— equipment required for processing;
— accessories and consumables required for processing;
— necessary maintenance of the medical device;
— post-market information;
— service life;
— necessary warnings.

The points above can also be of benefit to those validating alternative processes in accordance with the NOTE

2 to 5.2.

NOTE 2 Annex C provides information on classification of medical devices, which can assist with any risk

analysis process.
5 Validation of the processes identified in the information provided by the
medical device manufacturer

5.1 The medical device manufacturer shall validate each process that is identified in the information

supplied with the medical device and demonstrate that each process is suitable for processing of the

medical device. This shall include the intended points of contact with the user and/or the patient that

could likely lead to cross-contamination. Parts of the medical device that are unlikely to lead to cross

contamination may be excluded from validation, based upon the risk analysis described in Clause 4.

5.2 The medical device manufacturer shall have objective evidence available that validation of the

processing procedures has been undertaken to confirm that the specific medical device will be clean

and/or disinfected, when processed as directed.

NOTE 1 A worst-case approach, representing those areas of the medical device that are the intended points of

contact with the user, the patient or both and where there is opportunity for cross-contamination, can be used.

NOTE 2 In addition to the duty of a manufacturer to demonstrate the validity of provided information, national

authorities can require the effectiveness of the final process to be verified by the processor.

NOTE 3 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.

5.3 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

studies shall address the worst-case attribute(s) of the product family.
NOTE For guidance on grouping of medical devices as product families, see C.1.
6 Information to be provided by the medical device manufacturer
6.1 General

6.1.1 The information specified in this clause shall take into account the nature of the medical device,

its intended location for use and processing and its intended use.
© ISO 2021 – All rights reserved 5
---------------------- Page: 10 ----------------------
ISO 17664-2:2021(E)

NOTE The location of processing can be at the point of use or within a processing department.

6.1.2 The medical device manufacturer shall specify validated method(s) to reduce the risk of

transmission of infectious agents to a level appropriate for the intended use of the medical device.

6.1.3 Medical device manufacturers shall specify in their processing instructions any special

techniques and accessories that will enable the processor to provide a medical device that is suitable for

its intended use.

6.1.4 When providing processing instructions, medical device manufacturers shall be aware of:

— available national and international standards and guidelines;
— if applicable, the need for specific training;
— the processing equipment commonly available to the processor.

NOTE 1 Some national standards and regulations require cleaning and disinfection for all non-critical medical

devices.

NOTE 2 Annex A provides information which can assist with identifying the information required and the

processing equipment commonly available.

6.1.5 The equipment or materials required in the specified processes shall be identified by their

generic names or specification. Trade names may be added in cases where generic names do not provide

sufficient information (see Annex D).
6.2 Processing instructions

6.2.1 At least one validated method shall be specified for each applicable stage of processing of the

medical device. Disinfection may be carried out concurrently with cleaning of the medical device.

NOTE 1 Annex A provides information on the commonly used processes available.

NOTE 2 The requirements for cleaning and disinfection are stated as separate clauses in this document.

However, when the steps are concurrent, the requirements of both stages can be considered as one. In such cases

removal of soil, a reduction in microorganisms and inactivation of viable microorganisms can be achieved as a

result of the combination of applying the disinfecting agent and a physical action.

NOTE 3 The range of medical devices included within this document is wide and varied. Many of these

medical devices (e.g. stethoscopes and blood pressure cuffs) are relatively simple medical devices which do not

necessarily require automated processes. There will be other medical devices where automated processing is

not possible or contra-indicated (e.g. some medical devices with electronic components). However, some medical

devices such as beds, wheelchairs and footwear can be, and often are, subjected to automated processes. For this

final group of medical devices, a validated method of automated processing can be specified and is preferred.

6.2.2 The method shall be appropriate to the market in which the medical device is to be supplied.

6.2.3 The following information shall be stated where it is required for the maintenance of the intended

function of the medical device and the safety of the user(s) and the patient:
a) details of process steps;
b) a description of the equipment, the accessories or both;
c) specifications for process parameters and, if applicable, their tolerances.
NOTE For an example of an appropriate format see Annex B.

ISO 17664-2:2021(F)
Introduction

Le présent document s’applique aux fabricants de dispositifs médicaux non critiques destinés à être

nettoyés et/ou désinfectés par l’opérateur de procédé, afin de les rendre prêts à l’emploi ou au réemploi.

Sont inclus:

— les dispositifs médicaux destinés à être réutilisés et requérant un traitement pour les faire passer

de leur état «après utilisation clinique» à l’état «prêt à être réutilisé»;

— les dispositifs médicaux à usage unique requérant un traitement avant utilisation et destinés à être

utilisés dans un état nettoyé et/ou désinfecté.

Les importants progrès réalisés à la fois sur le plan des technologies et des connaissances ont permis

de développer des dispositifs médicaux complexes qui contribuent aux soins de santé des patients. Ces

avancées ont conduit à la conception de dispositifs médicaux potentiellement plus difficiles à nettoyer

et/ou désinfecter.

Les technologies de nettoyage et de désinfection ont également considérablement évolué au cours des

dix dernières années, aboutissant à de nouveaux systèmes et de nouvelles approches applicables au

traitement des dispositifs médicaux. Ces changements ont permis une meilleure prise en compte du

besoin de validation des procédés, notamment du nettoyage et/ou de la désinfection, afin de s’assurer

que les dispositifs médicaux sont traités efficacement. Ils ont également créé le besoin de s’assurer que

les fabricants de dispositifs médicaux fournissent des instructions adéquates, aidant les utilisateurs

finaux à traiter efficacement et en toute sécurité les dispositifs médicaux, en utilisant les équipements

et procédés disponibles.

Un dispositif médical requérant un traitement est fourni avec des instructions de traitement détaillées

afin d’assurer que, si celles-ci sont suivies correctement, les risques de transmission d’agents infectieux

sont réduits au minimum. En outre, un traitement efficace réduit au minimum le risque d’autres effets

néfastes sur les dispositifs médicaux.

Le nettoyage est une étape importante pour permettre la réutilisation ultérieure en toute sécurité

d’un dispositif médical utilisé. Les contaminants (par exemple, sang, tissus, microorganismes, agent

nettoyant et lubrifiants) qui ne sont pas éliminés des surfaces des dispositifs médicaux pourraient

compromettre le fonctionnement correct des dispositifs médicaux, leur utilisation en toute sécurité

(si cela est exigé) ainsi que tout procédé de désinfection ultérieur. Les dispositifs médicaux à usage

unique fournis par le fabricant de dispositifs médicaux de sorte qu’ils soient traités avant leur utilisation

peuvent également requérir un nettoyage avant toute poursuite du traitement.

Après le nettoyage, d’autres facteurs peuvent affecter l’utilisation sûre et efficace d’un dispositif

médical. Par exemple, des modes opératoires de contrôle et des essais de fonctionnement peuvent

s’avérer nécessaires pour s’assurer qu’un dispositif médical ne présente pas de risque pour la sécurité

à l’utilisation. Les fabricants de dispositifs médicaux peuvent aider les utilisateurs en leur fournissant

des instructions sur la manière dont il convient d’effectuer ces contrôles et essais.

Il est de la responsabilité des fabricants de dispositifs médicaux nécessitant un traitement de s’assurer

que la conception de ces dispositifs facilite la réalisation efficace dudit traitement. Cela inclut la prise

en compte des procédés validés les plus courants. Des exemples sont fournis dans l’Annexe A qui peut

servir de guide pour la validation des modes opératoires.

ISO 17664-2:2020(E)
Introduction

This document applies to manufacturers of non-critical medical devices that are intended to be cleaned,

disinfected or both by the processor to be made ready for use or reuse. 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 ready for their next use;

— single-use medical devices that require processing before use and are intended to be used in a clean

and/or disinfected state.

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 and disinfect.

Cleaning and disinfecting 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 and

disinfection in order to ensure that medical devices are effectively processed. These developments

have led to the need to ensure that manufacturers of 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 subsequent use. Failure to

remove contaminants (e.g. blood, tissues, microorganisms, cleaning agents and lubricants) from

surfaces of medical devices could compromise the correct functioning of the medical device, its safe

use and (if required) any subsequent disinfection process. 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 risk to safety 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.

The medical device manufacturer shall undertake risk analysis to determine the content and detail of

the information to be provided. The risk management undertaken by the manufacturer of the medical

device shall conform with ISO 14971.

NOTE 1 Some of the points relevant to processing that any risk analysis can require include:

— the likely points of contact with the user or the patient that might allow cross-contamination;

— nature and design of the medical device;
— nature of the contamination on the medical device;
— intended use;
4 PROOF/ÉPREUVE © ISO 2020 – All rights reserved
---------------------- Page: 9 ----------------------
ISO 17664-2:2020(E)
— foreseeable user error and misuse;
— user training;
— equipment required for processing;
— accessories and consumables required for processing;
— necessary maintenance of the medical device;
— post-market information;
— service life;
— necessary warnings.

The points above can also be of benefit to those validating alternative processes in accordance with the

NOTE 2 to 5.2.

NOTE 2 Annex C provides information on classification of medical devices, which can assist with any risk

analysis process.
5 Validation of the processes identified in the information provided by the
medical device manufacturer

5.1 The medical device manufacturer shall validate each process that is identified in the information

supplied with the medical device and demonstrate that each process is suitable for processing of the

medical device. This shall include the intended points of contact with the user, the patient or both that

could likely lead to cross-contamination. Parts of the medical device that are unlikely to lead to cross

contamination may be excluded from validation, based upon the risk analysis described in Clause 4.

5.2 The medical device manufacturer shall have objective evidence available that validation of the

processing procedures has been undertaken to confirm that the specific medical device will be clean,

disinfected or both, when processed as directed.

NOTE 1 A worst-case approach, representing those areas of the medical device that are the intended points of

contact with the user, the patient or both and where there is opportunity for cross-contamination, can be used.

NOTE 2 In addition to the duty of a manufacturer to demonstrate the validity of provided information, national

authorities can require the effectiveness of the final process to be verified by the processor.

NOTE 3 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.

5.3 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

studies shall address the worst-case attribute(s) of the product family.
NOTE For guidance on grouping of medical devices as product families, see C.1.
6 Information to be provided by the medical device manufacturer
6.1 General

6.1.1 The information specified in this clause shall take into account the nature of the medical device,

its intended location for use and processing and its intended use.

NOTE The location of processing can be at the point of use or within a processing department.

© ISO 2020 – All rights reserved PROOF/ÉPREUVE 5
---------------------- Page: 10 ----------------------
ISO 17664-2:2020(E)

6.1.2 The medical device manufacturer shall specify validated method(s) to reduce the risk of

transmission of infectious agents to a level appropriate for the intended use of the medical device.

6.1.3 Medical device manufacturers shall specify in their processing instructions any special

techniques and accessories that will enable the processor to provide a medical device that is suitable for

its intended use.

6.1.4 When providing processing instructions, medical device manufacturers shall be aware of:

— available national and international standards and guidelines;
— if applicable, the need for specific training;
— the processing equipment commonly available to the processor.

NOTE 1 Some national standards and regulations require cleaning and disinfection for all non-critical medical

devices.

NOTE 2 Annex A provides information which can assist with identifying the information required and the

processing equipment commonly available.

6.1.5 The equipment or materials required in the specified processes shall be identified by their

generic names or specification. Trade names may be added in cases where generic names do not provide

sufficient information (see Annex D).
6.2 Processing instructions

6.2.1 At least one validated method shall be specified for each applicable stage of processing of the

medical device. Disinfection may be carried out concurrently with cleaning of the medical device.

NOTE 1 Annex A provides information on the commonly used processes available.

NOTE 2 The requirements for cleaning and disinfection are stated as separate clauses in this document.

However, when the steps are concurrent, the requirements of both stages can be considered as one. In such cases

removal of soil, a reduction in microorganisms and inactivation of viable microorganisms can be achieved as a

result of the combination of applying the disinfecting agent and a physical action.

NOTE 3 The range of medical devices included within this document is wide and varied. Many of these

medical devices (e.g. stethoscopes and blood pressure cuffs) are relatively simple medical devices which do not

necessarily require automated processes. There will be other medical devices where automated processing is

not possible or contra-indicated (e.g. some medical devices with electronic components). However, some medical

devices such as beds, wheelchairs and footwear can be, and often are, subjected to automated processes. For this

final group of medical devices, a validated method of automated processing can be specified and is preferred.

6.2.2 The method shall be appropriate to the market in which the medical device is to be supplied.

6.2.3 The following information shall be stated where it is required for the maintenance of the intended

function of the medical device and the safety of the user(s) and the patient:
a) details of process steps;
b) a description of the equipment, the accessories or both;
c) specifications for process parameters and, if applicable, their tolerances.
NOTE For an example of an appropriate format see Annex B.
