Elektrische motorbetriebene handgeführte Werkzeuge, transportable Werkzeuge und Rasen- und Gartenmaschinen - Sicherheit - Teil 2-5: Besondere Anforderungen für handgeführte Kreissägen (IEC 62841-2-5:2014, modifiziert)

Outils électroportatifs à moteur, outils transportables et machines pour jardins et pelouses - Sécurité - Partie 2-5: Exigences particulières pour les scies circulaires portatives (IEC 62841-2-5:2014, modifiée)

L'IEC 62841-2-5:2014 s'applique aux scies circulaires portatives. La présente norme ne s'applique pas aux scies destinées à être utilisées avec des roues abrasives. Les scies destinées à être utilisées avec des roues abrasives comme des machines de coupe sont traitées dans l'IEC 62841-2-22. 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 is given in Annex K. 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. 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. 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 12 mois et au plus tard 36 mois après la date de publication. Mots-clés: Scie, Circulaire, Coupant Cette publication doit être lue conjointement avec la CEI 62841-1:2014.

Part 2-5: Particular requirements for hand-held circular 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.

International Standard IEC 62841-2-5 has been prepared by IEC technical committee 116:

Safety of motor-operated electric tools.
The text of this standard is based on the following documents:
FDIS Report on voting
116/166/FDIS 116/180/RVD

Full information on the voting for the approval of this 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 2-5 is to be used in conjunction with the first edition of IEC 62841-1 (2014).

This Part 2-5 supplements or modifies the corresponding clauses in IEC 62841-1, so as to

convert it into the IEC Standard: Particular requirements for hand-held circular saws.

Where a particular subclause of Part 1 is not mentioned in this Part 2-5, that subclause

applies as far as reasonable. 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 and figures which are additional to those in Part 1 are numbered starting

from 101.

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 publication will remain unchanged until

the stability date indicated on the IEC web site under "http://webstore.iec.ch" in the data

related to the specific publication. At this date, the publication 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.

8.14.1.101 Additional safety instructions for circular saws
8.14.101.1 General

The additional safety instructions as specified in 8.14.1.101.2 to 8.14.1.101.6 shall be given.

If in English they shall be verbatim and in the following order as applicable and equivalent in

any other language. This part may be printed separately from the "General Power Tool Safety

Warnings".

All notes are not to be printed; they are information for the designer of the manual.

8.14.1.101.2 Safety instructions for all saws
Cutting procedures
DANGER: Keep hands away from cutting area and the blade. Keep your second

hand on auxiliary handle, or motor housing. If both hands are holding the saw, they

cannot be cut by the blade.

NOTE For circular saws with a maximum blade diameter of 140 mm or smaller, the words "Keep your

second hand on auxiliary handle, or motor housing" do not apply.

b) Do not reach underneath the workpiece. The guard cannot protect you from the blade

below the workpiece.
---------------------- Page: 16 ----------------------
SIST EN 62841-2-5:2014
IEC 62841-2-5:2014 © IEC 2014 – 9 –

c) Adjust the cutting depth to the thickness of the workpiece. Less than a full tooth of

the blade teeth should be visible below the workpiece.

d) Never hold the workpiece in your hands or across your leg while cutting. Secure the

workpiece to a stable platform. It is important to support the work properly to minimise

body exposure, blade binding, or loss of control.

e) Hold the power tool by insulated gripping surfaces, when performing an operation

where the cutting tool may contact hidden wiring or its own cord. Contact with a "live"

wire will also make exposed metal parts of the power tool "live" and could give the

operator an electric shock.

f) When ripping, always use a rip fence or straight edge guide. This improves the

accuracy of cut and reduces the chance of blade binding.

g) Always use blades with correct size and shape (diamond versus round) of arbour

holes. Blades that do not match the mounting hardware of the saw will run off-centre,

causing loss of control.

h) Never use damaged or incorrect blade washers or bolt. The blade washers and bolt

were specially designed for your saw, for optimum performance and safety of operation.

8.14.1.101.3 Further safety instructions for all saws
Kickback causes and related warnings

– kickback is a sudden reaction to a pinched, jammed or misaligned saw blade, causing an
