IEC 62841-4-1:2017 are prefixed “Z”.
This European Standard follows the overall requirements of EN ISO 12100.
This document has been prepared under a mandate given to CENELEC by the European Commission
and the European Free Trade Association and supports essential requirements of EU Directive(s).
For the relationship with EU Directive(s), see informative Annex ZZ, which is an integral part of this
document.
Compliance with the clauses of Part 1 together with this Part 4-1 provides one means of conforming with
the essential health and safety requirements of the Directive concerned.
Endorsement notice
The text of the International Standard IEC 62841-4-1:2017 was approved by CENELEC as a European
Standard with agreed common modifications.
COMMON MODIFICATIONS
1 Scope
Add the following to the existing Clause 1:
This standard covers all significant hazards, hazardous situations or hazardous events relevant for tools
covered by this standard.
NOTE Z101 Essential requirements not mentioned in Table ZZ.1 are deemed to be not applicable, because the corresponding
hazards are either not significant for tools covered by this standard or do not require specific action by the designer.
Annex I
Replace the title of Annex I with the following:
Annex I
(normative)
Measurement of noise and vibration emissions
and delete the note.
Replace I.2.5.3 with the following:
I.2.5.3 Battery powered chain saws shall be tested with a fully charged battery using a saw
chain and the longest guide bar combination(s) as specified in 8.14.2 c) 101), under both of the
following conditions:
– no-load speed, with the highest setting of the speed control, if any; and
– at maximum speed, by applying, if necessary, an adjustable load by means of a water brake
(or equivalent) as specified in A.2.1 of ISO 22868:2011, which is increased starting from zero
(no-load) until the maximum speed is achieved.
NOTE The use of the adjustable load is only necessary for machines where the maximum speed occurs at part load.
For machines, where the maximum speed occurs at no-load, the application of an adjustable load is not necessary.
Four consecutive sound power level tests at no-load speed and four at maximum speed shall be
carried out. The resulting sound power level L is calculated by:
WA
0,1LL0,1
W1 W2
dB
L 10 lg 10+ 10
WA
where
is the arithmetic mean, rounded to the nearest decibel, of the four sound power level tests
L
W1
performed at no-load speed; and
=
L is the arithmetic mean, rounded to the nearest decibel, of the four sound power level tests
W2
performed at maximum speed.
During measurements, the machine shall operate under stable conditions. Once the noise
emission is steady, the measurement time interval shall be at least 15 s. If measurements are to
be made in octave or one-third octave frequency bands, the minimum period of observation shall
be 30 s for the frequency bands centred on or below 160 Hz, and 15 s for the frequency bands
centred on or above 200 Hz.
Annex K
(normative)
Battery tools and battery packs
K.1 Scope
Replace Note 102 with the following normative text:
This annex does not apply to chain saws equipped with integral batteries and with a maximum speed
of the saw chain exceeding 5 m/s.
Replace Subclause K.21.18 with the following:
K.21.18.Z101 Isolation and disabling device
Machines with an integral battery shall either be equipped
– with an isolation device to prevent the risk of injury from mechanical hazards during servicing or user
maintenance; or
– with a disabling device that prevents unintentional starting of the machine.
An isolation device shall
– provide disconnection of all poles of the battery from the serviceable region of the machine;
– be equipped with an unambiguous indication of the state of the disconnection device which
corresponds to each position of its manual control (actuator);
– be provided with protection against accidental reconnection.
NOTE 1 Examples of methods to achieve this disconnection include removable jumpers, integral batteries that can be
disconnected for servicing or user maintenance, or an electromechanical power switch with a direct mechanical link between the
actuator and the contact.
NOTE 2 The risk of accidental reconnection for a power switch is addressed by the requirement of 21.18.102. The other
examples in NOTE 1 achieve this by the necessary actions for reconnection.
A disabling device may be achieved by any of the following:
– a self-restoring or non-self-restoring lock-off device where two separate and dissimilar actions are
necessary before the motor is switched on (e.g. a power switch which has to be pushed in before it
can be moved laterally to close the contacts to start the motor). It shall not be possible to achieve
these two actions with a single grasping motion or a straight-line motion;
– a removable disabling device provided with the machine where it shall not be possible for the
machine to be operated when either applied or removed.
Compliance is checked by inspection and by manual test.
Annex L
(normative)
Battery tools and battery packs provided with mains connection or non-
isolated sources
L.1 Scope
Replace Note 102 with the following normative text:

– be equipped with an unambiguous indication of the state of the disconnection device which
corresponds to each position of its manual control (actuator);
– be provided with protection against accidental reconnection.
NOTE 1 Examples of methods to achieve this disconnection include removable jumpers, integral batteries that can be
disconnected for servicing or user maintenance, or an electromechanical power switch with a direct mechanical link between the
actuator and the contact.
NOTE 2 The risk of accidental reconnection for a power switch is addressed by the requirement of 21.18.102. The other
examples in NOTE 1 achieve this by the necessary actions for reconnection.
A disabling device may be achieved by any of the following:
– a self-restoring or non-self-restoring lock-off device where two separate and dissimilar actions are
necessary before the motor is switched on (e.g. a power switch which has to be pushed in before it
can be moved laterally to close the contacts to start the motor). It shall not be possible to achieve
these two actions with a single grasping motion or a straight-line motion;
– a removable disabling device provided with the machine where it shall not be possible for the

Part 4-1: Particular requirements for chain 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 62841-4-1 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
116/339/FDIS 116/344/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.
IEC 62841-4-1:2017 © IEC 2017 – 5 –
This Part 4-1 is to be used in conjunction with the first edition of IEC 62841-1 (2014).
This Part 4-1 supplements or modifies the corresponding clauses in IEC 62841-1, so as to
convert it into the IEC Standard: Particular requirements for chain saws.
Where a particular subclause of Part 1 is not mentioned in this Part 4-1, 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;
– terms defined in Clause 3: in bold typeface.
Subclauses, notes, tables and figures which are additional to those in Part 1, except as
described for Annex K and Annex L below, are numbered starting from 101.
Subclauses, notes, tables and figures in Annex K and Annex L which are additional to those in
the main body of this Part 4-1 as well as Annex K and Annex L of Part 1 are numbered
starting from 301.
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.
