Annex ZA
(informative)
Relationship between this European standard and the essential
requirements of Directive 93/42/EEC [OJ L 169] aimed to be covered

This European standard has been prepared under a Commission’s standardisation request M/023

concerning the development of European standards related to medical devices to provide one voluntary

means of conforming to essential requirements of Council Directive 93/42/EEC of 14 June 1993

concerning medical devices [OJ L 169].

Once this standard is cited in the Official Journal of the European Union under that Directive,

compliance with the normative clauses of this standard given in Table ZA.1 confers, within the limits of

the scope of this standard, a presumption of conformity with the corresponding essential requirements

of that Directive, and associated EFTA regulations.

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 Directive 93/42/EEC as amended by 2007/47/EC. This

means that risks have to be reduced ‘as far as possible’, ‘to a minimum’, ‘to the lowest possible level’, ‘minimized’

or ‘removed’, according to the wording of the corresponding essential requirement.

NOTE 2 The manufacturer’s policy for determining acceptable risk must be in compliance with Essential

Requirements 1, 2, 5, 6, 7, 8, 9, 11 and 12 of the Directive.

NOTE 3 This Annex ZA is based on normative references according to the table of references in the European

foreword, replacing the references in the core text.

NOTE 4 When an Essential Requirement does not appear in Table ZA.1, it means that it is not addressed by this

European Standard.

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. 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

any patent rights identified during the development of the document will be in the Introduction and/or

Introduction

This document is concerned with the extracorporeal blood circuit manufactured for single use

and intended for use in conjunction with haemodialysers, haemodiafilters and haemofilters. The

requirements specified in this document for the extracorporeal blood circuit will help to ensure safety

and satisfactory function.

It was not found practicable to specify materials of construction. This document therefore requires

only that materials have been tested and that the methods and results are made available upon request.

The dimensions of the connectors intended for connecting the extracorporeal blood circuit to a

haemodialyser, haemodiafilter or haemofilter have been revised and specified to ensure compatibility

with these devices, as specified in ISO 8637-1. The design and dimensions have been selected in order

to minimize the risk of leakage of blood and ingress of air. Connectors with either fixed or loose locking

shells are permitted.

This document reflects the consensus of physicians, manufacturers and other interested parties for

devices that are approved for clinical use.

INTERNATIONAL STANDARD ISO 8637-2:2018(E)
Extracorporeal systems for blood purification —
Part 2:
Extracorporeal blood circuit for haemodialysers,
haemodiafilters and haemofilters
1 Scope

WARNING — Other requirements and other EU Directives may be applicable to the product(s)

falling within the scope of this document.

This document specifies requirements for the blood circuit for devices used in extracorporeal blood

filtration therapies such as, but not limited to, haemodialysis, haemodiafiltration, haemofiltration and

transducer protectors (integral and non-integral) intended for use in such circuits.

This document does not apply to:
— haemodialysers, haemodiafilters or haemofilters;
— plasmafilters;
— haemoperfusion devices;
— vascular access devices;
— blood pumps;
— pressure monitors for the extracorporeal blood circuit;
— air detection devices;
— systems to prepare, maintain or monitor dialysis fluid;

— systems or equipment intended to perform haemodialysis, haemodiafiltration, haemofiltration or

haemoconcentration.

NOTE 1 Requirements for haemodialysers, haemodiafilters, haemofilters and haemoconcentrators are

specified in ISO 8637-1, and requirements for plasmafilters are specified in ISO 8637-3.

NOTE 2 Extracorporeal blood tubing sets can also be used for other extracorporeal therapies such as

haemoperfusion, plasmafiltration and plasma adsorption.
