Electric motor-operated hand-held tools, transportable tools and lawn and garden machinery - Safety - Part 4-2: Particular requirements for hedge trimmers
IEC 62841-4-2:2017 applies to hand-held hedge trimmers which are designed for use by one operator for trimming hedges and bushes, including extended-reach hedge trimmers with a maximum length of 3,5 m. The rated voltage is not more than 250 V for single-phase a.c. or d.c. tools, and 480 V for three-phase a.c. tools. The rated input is not more than 3 700 W. The limits for the applicability of this standard for battery tools are given in K.1 and L.1. This standard deals with the hazards presented by tools which are encountered by all persons in the normal use and reasonably foreseeable misuse of the tools. Hand-held electric tools, which can be mounted on a support or working stand for use as fixed tools without any alteration of the tool itself, are within the scope of this standard and such combination of a hand-held tool and a support is considered to be a transportable tool and thus covered by the relevant Part 3. This standard is not applicable to hedge trimmers with a rotating blade. This standard is not applicable to scissors type grass shears. This Part 4-2 is to be used in conjunction with the first edition of IEC 62841-1:2014. The attention of National Committees is drawn to the fact that equipment manufacturers and testing organizations may need a transitional period following publication of a new, amended or revised IEC publication in which to make products in accordance with the new requirements and to equip themselves for conducting new or revised tests. It is the recommendation of the committee that the content of this publication be adopted for implementation nationally not earlier than 36 months from the date of publication Key words: Hedge trimmer, Hand-held tool, Safety

Outils électroportatifs à moteur, outils portables et machines pour jardins et pelouses - Sécurité - Partie 4-2: Exigences particulières pour les taille-haies
IEC 62841-4-2:2017 s'applique aux taille-haies portatifs qui sont conçus pour être utilisés par un opérateur pour tailler les haies et les buissons, y compris les taille-haies télescopiques portatifs d’une longueur maximale de 3,5 m. La tension assignée est inférieure à 250 V pour les outils à courant monophasé alternatif ou continu, et inférieure à 480 V pour les outils à courant alternatif triphasé. La tension assignée est inférieure à 3 700 W. Les limites d'application de la présente Norme aux outils fonctionnant sur batterie sont indiquées en K.1 et L.1. La présente Norme traite des dangers présentés par les outils, encourus par tous les individus dans l'utilisation normale et dans l'utilisation impropre raisonnablement prévisible de ces outils. Les outils électroportatifs, qui peuvent être montés sur un support de travail pour être utilisés comme outils installés à poste fixe sans aucune modification de l'outil lui-même, sont compris dans le domaine d'application de la présente Norme et la combinaison d'un outil portatif et d'un support est considérée comme un outil portable, donc couvert par la Partie 3 applicable. La présente norme ne s'applique pas aux taille-haies avec une lame rotative. La présente norme ne s'applique pas aux cisailles à gazon de type ciseaux. La présente Partie 4-2 doit être utilisée conjointement avec la première édition de l'IEC 62841-1 (2014). L'attention des Comités Nationaux est attirée sur le fait que les fabricants d'appareils et les organismes d'essai peuvent avoir besoin d'une période transitoire après la publication d'une nouvelle publication IEC, ou d'une publication amendée ou révisée, pour fabriquer des produits conformes aux nouvelles exigences et pour adapter leurs équipements aux nouveaux essais ou aux essais révisés. Le comité recommande que le contenu de cette publication soit entériné au niveau national au plus tôt 36 mois après la date de publication. Mots clés: taille-haies, outil portable, sécurité

Part 4-2: Particular requirements for hedge trimmers
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 62841-4-2 has been prepared by IEC technical committee 116:
Safety of motor-operated electric tools.
The text of this International Standard is based on the following documents:
FDIS Report on voting
116/346/FDIS 116/352/RVD
Full information on the voting for the approval of this International Standard can be found in
the report on voting indicated in the above table.
This document has been drafted in accordance with the ISO/IEC Directives, Part 2.
– 6 – IEC 62841-4-2:2017 © IEC 2017
This Part 4-2 is to be used in conjunction with the first edition of IEC 62841-1 (2014).
This Part 4-2 supplements or modifies the corresponding clauses in IEC 62841-1, so as to
convert it into the IEC Standard: Particular requirements for hedge trimmers.
Where a particular subclause of Part 1 is not mentioned in this Part 4-2, that subclause
applies as far as relevant. Where this standard states “addition”, “modification” or
“replacement”, the relevant text in Part 1 is to be adapted accordingly.
The following print types are used:
– requirements: in roman type;
– test specifications: in italic type;
– notes: in small roman type.
The terms defined in Clause 3 are printed in bold typeface.
Subclauses, notes, tables and figures which are additional to those in Part 1, except as
described for Annex K and Annex L below, are numbered starting from 101.
Subclauses, notes, tables and figures in Annex K and Annex L which are additional to those in
the main body of this Part 4-2 as well as Annex K and Annex L of Part 1 are numbered
starting from 301.
A list of all parts of the IEC 62841 series, under the general title: Electric motor-operated
hand-held tools, transportable tools and lawn and garden machinery – Safety, 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.
NOTE The attention of National Committees is drawn to the fact that equipment manufacturers and testing
organizations may need a transitional period following publication of a new, amended or revised IEC publication in
which to make products in accordance with the new requirements and to equip themselves for conducting new or
revised tests.
It is the recommendation of the committee that the content of this publication be adopted for implementation
nationally not earlier than 36 months from the date of publication.
The contents of the corrigendum of June 2018 have been included in this copy.
