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.
IEC 60704-2-18 has been prepared by subcommittee 59C: Electrical heating appliances for
household and similar purposes, of IEC technical committee 59: Performance of household and
similar electrical appliances. It is an International Standard.
The text of this International Standard is based on the following documents:

This document is intended to be used in conjunction with IEC 60704‑1:2021, Household and
similar electrical appliances – Test code for the determination of airborne acoustical noise –
Part 1: General requirements.
The relevant text of IEC 60704‑1:2021 as amended by this publication establishes the test code
for electrical water heaters.
This document supplements or modifies the corresponding clauses in IEC 60704-1:2021. When
a particular subclause of IEC 60704‑1:2021 is not mentioned in this document, that subclause
is applicable as far as reasonable. Where this document states "addition", "modification",
"replacement" or "deletion", the relevant requirements, test specifications or explanatory matter
in IEC 60704‑1:2021 should be adapted accordingly.
Subclauses, figures and tables that are additional to those in IEC 60704‑1:2021 are numbered
starting from 101.

starting from 101, including those in a replaced clause or subclause.
A list of all the parts in the IEC 60704 series, under the general title Household and similar
electrical appliances – Test code for the determination of airborne acoustical noise, can be
found on the IEC website.
This document was drafted in accordance with ISO/IEC Directives, Part 2, and developed in
accordance with ISO/IEC Directives, Part 1 and ISO/IEC Directives, IEC Supplement, available
at www.iec.ch/members_experts/refdocs. The main document types developed by IEC are
