Electric Motor-Operated Hand-Held Tools, Transportable Tools and Lawn and Garden Machinery - Safety - Part 4-1: Particular requirements for chain saws
IEC 62841-4-1:2017 applies to chain saws for cutting wood and designed for use by one person. This standard does not cover chain saws designed for use in conjunction with a guide-plate and riving knife or in any other way such as with a support or as a stationary or transportable machine. This standard does not apply to chain saws for tree service as defined in ISO 11681-2; or pole-mounted pruners. Pole-mounted pruners will be covered by a future part of IEC 62841. The chain saws covered by this standard are designed only to be operated with the right hand on the rear handle and the left hand on the front handle. This Part 4-1 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.

Outils électroportatifs à moteur, outils portables et machines pour jardins et pelouses - Sécurité - Partie 4-1: Exigences particulières pour les scies à chaîne
IEC 62841-4-1:2017 s'applique aux scies à chaîne pour la découpe du bois et conçues pour être utilisées par une personne. La présente Norme ne couvre pas les scies à chaîne conçues pour être utilisées conjointement avec un guide-chaîne et une fendeuse, ni de toute autre manière (avec un support ou en tant que machine fixe ou portable, par exemple). La présente Norme ne s'applique pas aux scies à chaîne pour l'élagage telles que définies dans l'ISO 11681-2; ou aux élagueurs sur perche. Les élagueurs sur perche sont couverts par une partie ultérieure de l'IEC 62841. Les scies à chaîne couvertes par la présente Norme sont conçues uniquement pour être utilisées main droite sur la poignée arrière et main gauche sur la poignée avant. La présente Partie 4-1 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.

Part 2, 3 or 4: Requirements for particular types of tools which either supplement or modify the
requirements given in Part 1 to account for the particular hazards and characteristics of
these specific tools.
This Part 4-1 is to be used in conjunction with EN 62841-1:2015.
This Part 4-1 supplements or modifies the corresponding clauses in EN 62841-1:2015, so as to convert it
into the European 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. When 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 smaller roman type.
The terms defined in Clause 3 are printed in bold typeface.
Subclauses, notes, tables and figures which are additional to those in Part 1 are numbered starting
from 101.
Clauses, subclauses, notes, tables, figures and annexes which are additional to those in
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
