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 document 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).
ISO draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed patent
rights in respect thereof. As of the date of publication of this document, ISO had not received notice of (a)
patent(s) which may be required to implement this document. However, implementers are cautioned that
this may not represent the latest information, which may be obtained from the patent database available at
www.iso.org/patents. ISO shall not be held responsible for identifying any or all such patent rights.

This document was prepared by Technical Committee ISO/TC 150, Implants for surgery, Subcommittee
SC 2, Cardiovascular implants and extracorporeal systems, in collaboration with the European Committee for
Standardization (CEN) Technical Committee CEN/TC 205, Non-active medical devices, in accordance with the
Agreement on technical cooperation between ISO and CEN (Vienna Agreement).
This second edition cancels and replaces the first edition (ISO 23500-3:2019), which has been technically
revised.
The main changes are as follows:
— the use of WHO Drinking Water Guideline as the drinking water quality reference has replaced the
previously used EPA Water quality requirements;
— thallium has been removed from the list of contaminants of other trace elements in dialysis water as no
published study reports that this contaminant is of particular concern in the setting of haemodialysis;
— alternatives to classic microbial analytical methods (endotoxin testing using recombinant Factor C [rFC])
have been incorporated.

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 document contains the minimum chemical and microbiological requirements for the water to be used
for preparation of dialysis fluids and concentrates, and for the reprocessing of haemodialysers and the
necessary steps to ensure conformity with those requirements.
Haemodialysis and related therapies such as 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 regular surveillance 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 wate
