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).

---------------------- Page: 6 ----------------------
IEC 62841-2-1:2017 © IEC 2017 – 5 –
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.

5.17 Addition:
The mass of the tool includes the drill chuck and the auxiliary handle, if any.
6 Radiation, toxicity and similar hazards
This clause of Part 1 is applicable.
7 Classification
This clause of Part 1 is applicable.
8 Marking and instructions
This clause of Part 1 is applicable, except as follows:
8.1 Addition:
Drills and impact drills shall be marked with the following:
– rated no-load speed.
8.3 Addition:
Chucks of drills and impact drills shall be marked with the maximum capacity of the chuck.
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 Drill safety warnings
1) Safety instructions for all operations
a) Wear ear protectors when impact drilling. Exposure to noise can cause hearing
loss.
NOTE 1 The above warning applies only to impact drills and is omitted for drills.
b) Use the auxiliary handle(s). Loss of control can cause personal injury.
NOTE 2 The above warning applies only to tools that are provided with auxiliary handle(s).

---------------------- Page: 9 ----------------------
– 8 – IEC 62841-2-1:2017 © IEC 2017
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.
8.14.2 a) Additional items:
101) For diamond core drills: maximum diamond core bit diameter;
102) For tools with a maximum output torque greater than 100 Nm measured in accordance
with 19.102: instructions on how to brace the tool;
103) For applications which produce a considerable amount of dust, such as impact and
diamond core drilling: instruction on how to collect the dust.
9 Protection against access to live parts
This clause of Part 1 is applicable.
10 Starting
This clause of Part 1 is applicable.
11 Input and current
This clause of Part 1 is applicable.
12 Heating
This clause of Part 1 is applicable, except as follows:
12.2.1 Replacement:
Drills and impact drills are operated continuously until thermal equilibrium is reached with
the impact mechanism, if any, disengaged, while the torque applied to the spindle is 80 % of
the torque necessary to attain rated input or rated current.
12.5 Addition:

---------------------- Page: 10 ----------------------
IEC 62841-2-1:2017 © IEC 2017 – 9 –
For impact drills, the temperature-rise limit specified for the external enclosure does not
apply to the enclosure of the impact mechanism.
13 Resistance to heat and fire
This clause of Part 1 is applicable.
14 Moisture resistance
This clause of Part 1 is applicable.
15 Resistance to rusting
This clause of Part 1 is applicable.
16 Overload protection of transformers and associated circuits
This clause of Part 1 is applicable.
17 Endurance
This clause of Part 1 is applicable, except as follows:
17.2 Replacement for impact drills:
An impact drill is operated intermittently with no-load and, if the impact mechanism can be
engaged and disengaged at will, the impact mechanism shall remain disengaged for 12 h at a
voltage equal to 1,1 times the highest rated voltage or 1,1 times the upper limit of the rated
voltage range and then for 12 h at a supply voltage equal to 0,9 times the lowest rated
voltage or 0,9 times the lower limit of the rated voltage range. The 12 h of operation need
not be continuous. The speed is adjusted to the highest value of the highest range.
Each cycle of operation comprises an “on” period of 100 s and an “off” period of 20 s, the “off”
periods being included in the specified operating time.
During the test, the tool is placed in three different positions, the operating time, at each
voltage, being approximately 4 h for each position.
NOTE 101 The change of position is made to prevent abnormal accumulation of carbon dust in any particular
place. Examples of the three positions are horizontal, vertically up and vertically down.
The same tool is then mounted vertically in a test apparatus. The apparatus is designed to
apply sufficient axial force to the tool, through a resilient medium that absorbs impacts and
vibration, to ensure steady operation of the impact mechanism. An example of a test
apparatus is shown in Figure 101. The tool is then operated at rated voltage for four periods
of 6 h each, the interval between these periods being at least 30 min; if the impact mechanism
can be engaged and disengaged at will, the impact mechanism shall remain engaged.
During these tests, the tool is operated intermittently, each cycle comprising a period of
operation of 30 s and a rest period of 90 s during which the tool remains switched off.
The tool may be switched on and off by means of a switch other than that incorporated in the
tool.

---------------------- Page: 11 ----------------------
– 10 – IEC 62841-2-1:2017 © IEC 2017
During these tests, replacement of the carbon brushes is allowed, and the tool is oiled and
greased as in normal use. If mechanical failure occurs and does not impair compliance with
this standard, the part that failed may be replaced.
If the temperature rise of any part of the tool exceeds the temperature rise determined during
the test of 12.1, forced cooling or rest periods may be applied, the rest periods being
excluded from the specified operating time. If forced cooling is applied, it shall not alter the air
flow of the tool or redistribute carbon deposits.
During these tests, overload protection devices incorporated in the tool shall not activate.
NOTE 102 Monitoring of external temperatures will help avoid mechanical failures.
