Household and similar electrical appliances - Test code for the determination of airborne acoustical noise - Part 2-8: Particular requirements for electric shavers, hair clippers or trimmers

IEC 60704-2-8:2020 is available as IEC 60704-2-8:2020 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.IEC 60704-2-8:2020 applies to electric shavers, clippers or trimmers for domestic and similar use, supplied from mains or secondary batteries or primary batteries. The term "similar use" is understood to mean the use in hotels, hospitals, shops, offices, etc. This document does not apply to shavers, clippers or trimmers that are powered by means other than electrical, for example by a spring-device. If possible, this document can also be applied to analogous electrically operated devices, such as depilating devices. This second edition cancels and replaces the first edition published in 1997. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) the scope of the products has been enlarged to include hair clippers and trimmers; b) it includes standard deviations of sound power levels in 1.1.3; c) the normative references have been updated (ISO 3744:2010 and ISO 3743-1:2010); d) it is adjusted with respect to IEC 60704-1:2010; e) it has been updated to comply with the ISO/IEC Directives, Part 2. This Part 2-8 is intended to be used in conjunction with 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. This Part 2-8 supplements or modifies the corresponding clauses in IEC 60704-1:2010, so as to establish the test code for shavers, hair clippers or trimmers.

IEC 60704-2-8:2020 est disponible sous forme de IEC 60704-2-8:2020 RLV qui contient la Norme internationale et sa version Redline, illustrant les modifications du contenu technique depuis l'édition précédente.L'IEC 60704-2-8:2020 s'applique aux rasoirs et aux tondeuses à barbe ou à cheveux électriques pour usages domestiques et analogues, alimentés à partir du réseau ou par piles ou accumulateurs. Le terme "usages analogues" couvre les usages dans les hôtels, hôpitaux, magasins, bureaux, etc. Le présent document ne s'applique pas aux rasoirs et aux tondeuses à barbe ou à cheveux qui ne sont pas alimentés par des moyens électriques (mais par un dispositif à ressort, par exemple). Si possible, le présent document peut également être appliqué aux appareils électriques analogues tels que les appareils d'épilation. Cette deuxième édition annule et remplace la première édition parue en 1997. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente: a) le domaine d'application des produits a été élargi aux tondeuses à barbe et à cheveux; b) des écarts-types sont fournis pour les niveaux de puissance acoustique au 1.1.3; c) les références normatives ont été mises à jour (ISO 3744:2010 et ISO 3743-1:2010); d) le présent document a fait l'objet de réajustements par rapport à l'IEC 60704-1:2010; e) le présent document a été mis à jour pour être conforme aux Directives ISO/IEC, Partie 2. La présente Partie 2-8 est destinée à être utilisée conjointement avec la troisième édition (2010) de l'IEC 60704-1, Appareils électrodomestiques et analogues - Code d'essai pour la détermination du bruit aérien - Partie 1: Exigences générales. La présente Partie 2-8 complète ou modifie les articles correspondants de l’IEC 60704-1:2010, de façon à constituer le code d'essai pour les rasoirs et les tondeuses à barbe ou à cheveux.

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 60704-2-8 has been prepared by subcommittee 59L: Small
household appliances, of IEC technical committee 59: Performance of household and similar
electrical appliances.
This second edition cancels and replaces the first edition published in 1997. This edition
constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) the scope of the products has been enlarged to include hair clippers and trimmers;
b) it includes standard deviations of sound power levels in 1.1.3;
c) the normative references have been updated (ISO 3744:2010 and ISO 3743-1:2010);
