FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
International standard IEC 60734 has been prepared by subcommittee 59D: Home laundry
appliances, of IEC Technical Committee 59: Performance of household and similar electrical
appliances.
This fourth edition cancels and replaces the third edition published in 2001. This edition
constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) four types of standard water, from soft to very hard, are defined with specification for
hardness, alkalinity and conductivity;
b) preparation method A is no longer maintained; and
c) method C3 is added to prepare water of specified hardness, conductivity and alkalinity
starting with natural water while the natural water based methods C1 and C2 focus on
water hardness only, without allowing control or setting of alkalinity and conductivity.

INTRODUCTION
This publication specifies water qualities with regard to hardness, alkalinity and conductivity
and describes several methods to prepare water to be used for testing household appliances
in cases where the water quality is important for the reproducibility of the test results. The
described methods allow the preparation of water complying with all three target requirements
(hardness, alkalinity, conductivity), or just hardness – depending on the requirements set
out in the referring appliance test method.
Compared to the third edition of IEC 60734 (2001), method A is no longer maintained and
another method, method C3, is added.
Method B is used to prepare water of the correct total hardness. Preparation starts with
demineralised water in which hardening salts are dissolved. It will give water specified
temporary as well as permanent hardness, whilst complying with the specifications for
alkalinity and conductivity.
Method C1 starts with natural water with higher hardness than required, while method C2
starts with soft natural water, which is hardened. Depending on the composition of the natural
water, several other ions might be present. Restrictions regarding the amounts are given for
some ions, which may influence the cleaning results when testing washing machines and
dishwashers. No specification regarding temporary and permanent hardness is given.
The development of method C3 appreciates the need for water of specified conductivity and
alkalinity for testing the performance of tumble dryers. While synthetic method B meets this
need, the natural water based methods C1 and C2 focus on water hardness only without
allowing control or setting of alkalinity and conductivity. The new method C3, which starts
with natural water, fills that gap.
