Annex ZA
(informative)
Relationship between this European Standard and the General Safety and
Performance requirements of Regulation (EU) 2017/745 aimed to be
covered
This European standard has been prepared under M/575 to provide one voluntary means of
conforming to the General Safety and Performance Requirements of Regulation (EU) 2017/745 of 5
April 2017 concerning medical devices [OJ L 117] and to system or process requirements including
those relating to quality management systems, risk management, post-market surveillance systems,
clinical investigations, clinical evaluation or post-market clinical follow-up.
Once this standard is cited in the Official Journal of the European Union under that Regulation,
compliance with the normative clauses of this standard given in Table ZA.1 and application of the
edition of the normatively referenced standards as given in Table ZA.2 confers, within the limits of the
scope of this standard, a presumption of conformity with the corresponding General Safety and
Performance Requirements of that Regulation, and associated EFTA Regulations.
Where a definition in this standard differs from a definition of the same term set out in Regulation (EU)
2017/745, the differences shall be indicated in this Annex Z. For the purpose of using this standard in
support of the requirements set out in Regulation (EU) 2017/745, the definitions set out in this
Regulation prevail. In this context, the definition of ‘medical device’ in EN ISO 17664-2 is a modified
version of the definition prepared by the Global Harmonization Task Force with modification to the
Note in the definition.
Where the European standard is an adoption of an International Standard, the scope of this standard
can differ from the scope of the European Regulation that it supports. As the scope of the applicable
regulatory requirements differ from nation to nation and region to region, the standard can only
support European regulatory requirements to the extent of the scope of the European regulation for
medical devices (EU) 2017/745).
NOTE 1 Where a reference from a clause of this standard to the risk management process is made, the risk
management process needs to be in compliance with Regulation (EU) 2017/745. This means that risks have to be
‘reduced as far as possible’, ‘reduced to the lowest possible level’, ‘reduced as far as possible and appropriate’,
‘removed or reduced as far as possible’, ‘eliminated or reduced as far as possible’, ’removed or minimized as far as
possible’, or ‘minimized’, according to the wording of the corresponding General Safety and Performance
Requirement.
NOTE 2 The manufacturer’s policy for determining acceptable risk must be in compliance with General Safety
and Performance Requirements 1, 2, 3, 4, 5, 8, 9, 10, 11, 14, 16, 17, 18, 19, 20, 21 and 22 of the Regulation.
NOTE 3 When a General Safety and Performance Requirement does not appear in Table ZA.1, it means that it is
not addressed by this European Standard.
Table ZA.1 — Correspondence between this European Standard and Annex I of
Regulation (EU) 2017/745 [OJ L 117] and to system or process requirements including those relating

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.

4 Risk analysis
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 (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

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 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
