Endorsement notice
The text of ISO 13959:2014 has been approved by CEN as EN ISO 13959:2015 without any modification.
Annex ZA
(informative)
Relationship between this European Standard and the Essential
Requirements of EU Directive 93/42/EEC on medical devices
This European Standard has been prepared under a mandate given to CEN by the European
Commission and the European Free Trade Association to provide a means of conforming to Essential
Requirements of the New Approach Directive 93/42/EEC on medical devices.
Once this standard is cited in the Official Journal of the European Union under that Directive and has
been implemented as a national standard in at least one Member State, compliance with the 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 (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
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www.iso.org/patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.

assessment, as well as information about ISO’s adherence to the WTO principles in the Technical Barriers

Introduction
Assurance of adequate water quality is one of the most important aspects of ensuring a safe and effective
delivery of haemodialysis, haemodiafiltration, or haemofiltration.
This International Standard contains minimum requirements, chemical and microbiological, for the water
to be used for preparation of dialysis fluids, concentrates, and for the reprocessing of haemodialysers
and the necessary steps to ensure compliance with those requirements.
Haemodialysis and haemodiafiltration can expose the patient to more than 500 l of water per week across
the semi-permeable membrane of the haemodialyser or haemodiafilter. Healthy individuals seldom have
a weekly oral intake above 12 l. This over 40-fold increase in exposure requires control and monitoring of
water quality to avoid excesses of known or suspected harmful substances. Since knowledge of potential
injury from trace elements and contaminants of microbiological origin over long periods is still growing
and techniques for treating drinking water are continuously developed, this International Standard
will evolve and be refined accordingly. The physiological effects attributable to the presence of organic
contaminants in dialysis water are important areas for research. At the time this International Standard
was published it was not possible to specify threshold values for organic contaminants permitted in
water used for the preparation of dialysis fluids, concentrates, and reprocessing of haemodialysers. The
issue of organic contaminants will be reassessed on the next revision of this International Standard.
Within this International Standard, measurement techniques current at the time of publication have
been cited. Other st
