Electric motor-operated hand-held tools, transportable tools and lawn and garden machinery - Safety - Part 3-9: Particular requirements for transportable mitre saws
IEC 62841-3-9:2020 applies to transportable mitre saws intended to be used with a toothed saw blade for cutting wood and analogous materials, plastics and nonferrous metals except magnesium with a saw blade diameter not exceeding 410 mm, which hereinafter might simply be referred to as saw or tool. This International Standard does not apply to mitre saws intended to cut other metals, such as magnesium, steel and iron. This document does not apply to mitre saws with an automatic feeding device. Transportable saws intended to cut ferrous metals will be covered by a future part of IEC 62841-3. This document does not apply to saws designed for use with abrasive wheels. Transportable tools designed for use with abrasive wheels are covered by IEC 62841-3-10. This document does not apply to tools combining the function of a mitre saw with the function of a table saw. Transportable tools combining the function of a mitre saw with the function of a table saw are covered by by a future part of IEC 62841-3. This second edition cancels and replaces the first edition published in 2014. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
- Clause 1: Scope: increase of the maximum saw blade diameter to 410 mm;
- Corrigendum 1 and Corrigendum 2 of the first edition have been incorporated in this second edition.
This Part 3-9 is to be used in conjunction with the IEC 62841-1:2014.

Outils électroportatifs à moteur, outils portables et machines pour jardins et pelouses - Sécurité - Partie 3-9: Exigences particulières pour les scies à onglets transportables
L'IEC 62841-3-9:2020 s'applique aux scies à onglets transportables destinées à être utilisées avec une lame de scie dentée pour la coupe du bois et de matériaux analogues, de plastiques et de métaux non ferreux à l'exception du magnésium, la lame de scie ayant un diamètre ne dépassant pas 410 mm, celle-ci pouvant être simplement désignée ci-après comme scie ou outil. La présente Norme internationale ne s'applique pas aux scies à onglets utilisées pour couper d'autres métaux, tels que le magnésium, l'acier et le fer. Le présent document ne s'applique pas aux scies à onglets équipées d'un appareil d'alimentation automatique. Les scies transportables destinées à couper des métaux ferreux seront couvertes par une future partie de l’IEC 62841-3. Le présent document ne s'applique pas aux scies destinées à être utilisées avec un disque abrasif. Les outils portables conçus pour être utilisés avec un disque abrasif sont couverts par l’IEC 62841-3-10. Le présent document ne s'applique pas aux outils qui combinent la fonction de scie à onglets et la fonction de scie circulaire à table. Les outils portables qui combinent la fonction de scie à onglets et la fonction de scie circulaire à table sont couverts par une future partie de l’IEC 62841-3. Cette deuxième édition annule et remplace la première édition parue en 2014. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente:
- Article 1: Domaine d'application: augmentation du diamètre maximal de la lame de scie à 410 mm;
- Le Corrigendum 1 et le Corrigendum 2 de la première édition ont été incorporés dans la présente deuxième édition.
La présente Partie 3-9 doit être utilisée conjointement avec l’IEC 62841-1:2014.

Part 3-9: Particular requirements for transportable mitre saws
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.
This redline version of the official IEC Standard allows the user to identify the changes
made to the previous edition. A vertical bar appears in the margin wherever a change
has been made. Additions are in green text, deletions are in strikethrough red text.
International Standard IEC 62841-3-9 has been prepared by IEC technical committee 116:
Safety of motor-operated electric tools.
This second edition cancels and replaces the first edition published in 2014. This edition
constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) Clause 1: Scope: increase of the maximum saw blade diameter to 410 mm;
b) Corrigendum 1 and Corrigendum 2 of the first edition have been incorporated in this
second edition.
The text of this International Standard is based on the following documents:
FDIS Report on voting
116/430/FDIS 116/442/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 publication has been drafted in accordance with the ISO/IEC Directives, Part 2.
This Part 3-9 is to be used in conjunction with the IEC 62841-1:2014.
This Part 3-9 supplements or modifies the corresponding clauses in IEC 62841-1, so as to
convert it into the IEC Standard: Particular requirements for transportable mitre saws.
Where a particular subclause of Part 1 is not mentioned in this Part 3-9, that subclause
applies as far as reasonable. Where this standard states “additi
