(Main)Electric motor-operated hand-held tools, transportable tools and lawn and garden machinery - Safety - Part 4-1: Particular requirements for chain saws
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 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 s
