Part 2-6: Particular requirements for hand-held hammers
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 62841-2-6 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
116/459/FDIS 116/466/RVD

This Part 2-6 supplements or modifies the corresponding clauses in IEC 62841-1, so as to
convert it into the IEC Standard: Particular requirements for hand-held hammers.
Where a particular subclause of Part 1 is not mentioned in this Part 2-6, 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 in 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.
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.

8 Marking and instructions
This clause of Part 1 is applicable, except as follows:
8.14.1 Addition:
The additional safety instructions as specified in 8.14.1.101 shall be given. This part may be
printed separately from the "General Power Tool Safety Warnings".
8.14.1.101 Hammer safety warnings
1) Safety instructions for all operations
a) Wear ear protectors. Exposure to noise can cause hearing loss.
b) Use auxiliary handle(s), if supplied with the tool. Loss of control can cause
personal injury.
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 101 The above warning applies only for rotary hammers 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 102 For rotary hammers that can also be used as screwdrivers, the words "or fasteners" are
added after "cutting accessory".

2) Safety instructions when using long drill bits with rotary hammers
NOTE 103 The warnings in this section apply only to rotary hammers.
a) 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.
b) 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.
8.14.2 a) Addition:
101) For tools with a maximum output torque greater than 100 Nm measured in accordance
with 19.102: instructions on how to brace the tool;
102) Instructions for assembling any attachments that are supplied with the tool;
