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).

changes compared to the previous edition are as follows:
— The document forms part of a revised and renumbered series dealing with the preparation and
quality management of fluids for haemodialysis and related therapies. The series comprise
ISO 23500-1 (previously ISO 23500), ISO 23500-2, (previously ISO 26722), ISO 23500-3, (previously
ISO 13959), ISO 23500-4, (previously ISO 13958), and ISO 23500-5, (previously ISO 11663).

ISO 23500-3:2019(E)
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 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 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 water are
continuously developed, this document will evolve and be refined accordingly. The physiological effects
attributable to the presence of organic contaminants in dialysis water are important areas for research,
however, the effect of such contaminants on patients receiving regular dialysis treatment is largely
unknown, consequently no threshold values for organic contaminants permitted in water used for the
preparation of dialysis fluids, concentrates, and reprocessing of haemodialysers has been specified in
this revised document.
Within this document, measurement techniques current at the time of publication have been cited.
Other standard methods can be used, provided that such methods have been appropriately validated
and are comparable to the cited methods.
The final dialysis fluid is produced from concentrates or salts manufactu
