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.

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:
0,1LL0,1
W1 W2
 dB
L 10 lg 10+ 10
where

is the arithmetic mean, rounded to the nearest decibel, of the four sound power level tests

performed at no-load speed; and
---------------------- Page: 6 ----------------------
SIST EN 62841-4-1:2020
EN 62841-4-1:2020 (E)

L is the arithmetic mean, rounded to the nearest decibel, of the four sound power level tests

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

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
