Electric motor-operated hand-held tools, transportable tools and lawn and garden machinery - Safety - Part 2-1: Particular requirements for hand-held drills and impact drills

IEC 62841-2-1:2017 applies to hand-held drills and impact drills, including diamond core drills. This standard also applies to drills that can be used for driving screws by attaching screwdriver bits.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 does not apply to rotary hammers, even if they can be used as a drill. This Part 2-1 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: Drill, Impact Drill, Hand-held tool, Safety

Elektrische motorbetriebene handgeführte Werkzeuge, transportable Werkzeuge und Rasen- und Gartenmaschinen - Sicherheit - Teil 2-1: Besondere Anforderungen für handgeführte Bohrmaschinen und Schlagbohrmaschinen

Outils électroportatifs à moteur, outils portables et machines pour jardins et pelouses - Sécurité - Partie 2-1: Exigences particulières pour les perceuses portatives et les perceuses à percussion

IEC 62841-2-1:2017 s’applique aux perceuses portatives et aux perceuses à percussion y compris les perceuses à diamant. La présente norme s’applique également aux perceuses pouvant être utilisées pour enfoncer des vis lorsque des embouts de visseuse leur sont ajoutés. 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 marteaux rotatifs, même s’ils peuvent être utilisés comme une perceuse. La présente Partie 2-1 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: perceuses, perceuses à percussion, outil portatif, sécurité

IEC 62841-2-1:2017 se uporablja za ročne vrtalnike in udarne vrtalnike, vključno z vrtalniki, ki omogočajo uporabo diamantnih svedrov. Ta standard se uporablja tudi za vrtalnike, ki jih je mogoče uporabljati za vijačenje s pritrditvijo nastavkov vijačnika. Nazivna napetost ne presega 250 V za enofazna orodja na enosmerni ali izmenični tok in 480 V za trifazna orodja na izmenični tok. Nazivna vhodna moč ne presega 3700 W. Omejitve uporabnosti tega standarda za baterijska orodja so podane v točkah K.1 in L.1. Ta standard obravnava tveganja, ki jih predstavljajo orodja in katerim so izpostavljene vse osebe pri običajni uporabi ter pričakovani nepravilni uporabi orodij. Ročna električna orodja, ki jih je mogoče pritrditi na opornik ali delovno stojalo, pri čemer se jih brez kakršnih koli sprememb samega orodja uporablja kot fiksna orodja, spadajo na področje uporabe tega standarda. Kombinacija ročnega orodja in takšnega stojala se obravnava kot prenosno orodje, ki je zajeto v ustreznem 3. delu.
Ta standard se ne uporablja za rotacijska kladiva, tudi če se ta lahko uporabljajo kot vrtalnik.
Ta del 2-1 je treba uporabljati v povezavi s prvo izdajo standarda IEC 62841-1:2014.
Nacionalni odbori morajo upoštevati, da bodo proizvajalci opreme in organizacije za preskušanje morda potrebovali prehodno obdobje po objavi nove, spremenjene ali popravljene objave IEC, da bodo lahko izdelovali izdelke v skladu z novimi zahtevami in se opremili za izvajanje novih ali spremenjenih preskusov.
Odbor priporoča, da se vsebina te objave sprejme v nacionalno uporabo najpozneje 36 mesecev od datuma objave.

ELECTRIC MOTOR-OPERATED HAND-HELD TOOLS, TRANSPORTABLE
TOOLS AND LAWN AND GARDEN MACHINERY – SAFETY –
Part 2-1: Particular requirements for hand-held drills and impact drills
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 62841-2-1 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
116/321/FDIS 116/330/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.

This Part 2-1 is to be used in conjunction with the first edition of IEC 62841-1 (2014).

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

convert it into the IEC Standard: Particular requirements for hand-held drills and impact drills.

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

IMPORTANT – The 'colour inside' logo on the cover page of this publication indicates

that it contains colours which are considered to be useful for the correct

understanding of its contents. Users should therefore print this document using a

colour printer.

c) Brace the tool properly before use. This tool produces a high output torque and

without properly bracing the tool during operation, loss of control may occur resulting

in personal injury.

NOTE 3 The above warning applies only for tools with a maximum output torque greater than 100 Nm

measured in accordance with 19.102.
d) Hold the power tool by insulated gripping surfaces, when performing an
operation where the cutting accessory may contact hidden wiring or its own

cord. Cutting accessory contacting a "live" wire may make exposed metal parts of the

power tool "live" and could give the operator an electric shock.

NOTE 4 For drills that can also be used as screwdrivers, the words “or fasteners” are added after

“cutting accessory”.
2) Safety instructions when using long drill bits

a) Never operate at higher speed than the maximum speed rating of the drill bit. At

higher speeds, the bit is likely to bend if allowed to rotate freely without contacting the

workpiece, resulting in personal injury.
b) Always start drilling at low speed and with the bit tip in contact with the

workpiece. At higher speeds, the bit is likely to bend if allowed to rotate freely without

contacting the workpiece, resulting in personal injury.
c) Apply pressure only in direct line with the bit and do not apply excessive

pressure. Bits can bend causing breakage or loss of control, resulting in personal

injury.
