L'IEC 60704-2-16:2019 s'applique aux lavantes-séchantes électriques en un seul équipement pour une utilisation domestique ou similaire prévue avec un placement au sol contre un mur, une intégration ou un placement sous un comptoir, un plan de travail de cuisine ou sous un évier, pour une fixation murale ou sur un comptoir. La présente norme concerne des méthodes objectives de degré de précision «expertise» destinées à déterminer les niveaux de puissance acoustique d'un bruit aérien situé à l'intérieur du domaine de fréquences utile. Les exigences pour la déclaration des valeurs d'émission sonore ne relèvent pas du domaine d'application du présent document. La présente partie est destinée à être utilisée conjointement avec l'IEC 60704-1:2010.

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 60704-2-16 has been prepared by subcommittee 59D: Home and

similar laundry appliances of IEC technical committee 59: Performance of household and

similar electrical appliances.
The text of this International Standard is based on the following documents:

This Part 2-16 is intended to be used in conjunction with the third edition (2010) of

IEC 60704-1, Household and similar electrical appliances – Test code for the determination of

airborne acoustical noise – Part 1: General requirements.
NOTE When "Part 1" is mentioned in this standard, it refers to IEC 60704-1:2010.

The relevant text of Part 1 as amended by this publication establishes the test code for

washer-dryers.

This Part 2-16 supplements or modifies the corresponding clauses in IEC 60704-1. When a

particular subclause of Part 1 is not mentioned in this Part 2-16, that subclause is applicable

as far as reasonable. Where this standard states "addition", "modification" or "replacement",

the relevant requirements, test specifications or explanatory matter in Part 1 should be

adapted accordingly.

Subclauses and tables that are additional to those in Part 1 are numbered starting from 101.

Unless notes are in a new subclause or involve notes in Part 1, they are numbered 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.

The committee has decided that the contents of this document will remain unchanged until the

stability date indicated on the IEC website under "http://webstore.iec.ch" in the data related to

the specific document. At this date, the document will be
• reconfirmed,
• withdrawn,
• replaced by a revised edition, or
• amended.

INTRODUCTION

The noise of washer-dryers has been measured up to now by making use of two standards,

IEC 60704-2-4 and IEC 60704-2-6. This first edition of IEC 60704-2-16 makes it possible to

test the noise of washer-dryers by using one single standard. The following significant

technical changes with respect to the separate use of IEC 60704-2-4:2011 and
IEC 60704-2-6:2012 have been introduced:
• measurement uncertainty and standard deviations are taken into account,

• definition of periods and cycles, in particular definition of thermal spin period and

continuous cycle,
• definitions of standard test programme and standard test load,
• location and mounting,
• information to be reported.

The measuring conditions specified in this document provide for sufficient accuracy in

determining the noise emitted and comparing the results of measurements taken by different

laboratories, whilst simulating as far as possible the practical use of household washer-

dryers.

It is recommended to consider the determination of noise levels as part of a comprehensive

testing procedure covering many aspects of the properties and performance of household

washer-dryers.

NOTE As stated in the introduction to IEC 60704-1, this test code is concerned with airborne noise only.

Replacement:

The method specified in ISO 3744 is applicable to noise sources of any size. When applying

ISO 3743-1 and ISO 3743-2, care should be taken that the maximum size of the washer-

dryers under test fulfils the requirements specified in 1.2 of ISO 3743-1:2010 and 1.3 of

ISO 3743-2:1994.
