Overview

EN IEC 60704-2-18:2022 - Household and similar electrical appliances - Test code for the determination of airborne acoustical noise - Part 2-18: Particular requirements for electric water heaters - specifies particular acoustic test requirements for single‑unit electric water heaters used in homes and similar environments. It is intended to be used together with IEC 60704‑1:2021 (general requirements) and focuses on the determination of airborne acoustical noise (sound pressure and sound power) emitted by electric water heaters.

This standard covers appliances intended for:

• floor placement (against a wall),
• built-in or under‑counter / under‑sink installation,
• wall‑mounting,
• countertop placement.

It excludes combustion heaters, water kettles, heat‑pump water heaters, conventional electric storage water heaters (as defined in IEC 60335‑2‑21:2012), and instantaneous electric water heaters without any noise‑producing components.

Key topics and technical requirements

EN IEC 60704‑2‑18:2022 supplements or modifies clauses of IEC 60704‑1:2021 and addresses:

• Measurement methods and acoustic environments - selection of test environments and measuring procedures to ensure comparability between laboratories.
• Instrumentation - requirements for microphones, analysers and calibration when measuring airborne acoustical noise.
• Operation and location of the appliance under test - prescribed mounting/installation and operating conditions reflecting realistic household use.
• Measurement of sound pressure levels and calculation of sound power levels - procedures for acquiring, processing and converting measured data.
• Information to be recorded and reported - mandatory test data, conditions and results to ensure transparency and repeatability.
• Normative annexes (e.g., standard test table) and bibliographic references.

The document aims to capture special noise sources present in some products (for example motors and pumps) and disregards sporadic, low‑level control noise.

Practical applications and users

Who uses this standard:

• Manufacturers and R&D teams of electric water heaters for product design, noise reduction and quality control.
• Acoustic test laboratories performing standardized noise measurement and certification.
• Regulatory bodies and conformity assessment organizations verifying declared noise levels for labeling or market surveillance (e.g., EU energy‑labelling schemes).
• Product compliance and technical documentation authors.

Practical benefits:

• Enables consistent, repeatable measurement of airborne acoustical noise across labs.
• Supports product improvements (reduced noise) and prevents misleading noise declarations in regulatory contexts.

• IEC 60704‑1:2021 - General requirements (used in conjunction).

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.
