Electric motor-operated hand-held tools, transportable tools and lawn and garden machinery - Safety - Part 2-5: Particular requirements for hand-held circular saws
IEC 62841-2-5:2014 applies to hand-held circular saws. This standard does not apply to saws designed for use with abrasive wheels. Saws designed for use with abrasive wheels as cut-off machines are covered by IEC 62841-2-22. The rated voltage is not more than 250 V for single-phase a.c. or d.c. tools, and 480 V for three-phase a.c. tools. The rated input is not more than 3 700 W. The limits for the applicability of this standard for battery tools is given in Annex K. This standard deals with the hazards presented by tools which are encountered by all persons in the normal use and reasonably foreseeable misuse of the tools. Hand-held electric tools, which can be mounted on a support or working stand for use as fixed tools without any alteration of the tool itself, are within the scope of this standard and such combination of a hand-held tool and a support is considered to be a transportable tool and thus covered by the relevant Part 3. 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. Key words: Saw, Circular, Cutting,
This publication is to be read in conjunction with IEC 62841-1:2014.
Outils électroportatifs à moteur, outils portables et machines pour jardins et pelouses - Sécurité - Partie 2-5: Exigences particulières pour les scies circulaires portatives
L'IEC 62841-2-5:2014 s'applique aux scies circulaires portatives. La présente norme ne s'applique pas aux scies destinées à être utilisées avec des roues abrasives. Les scies destinées à être utilisées avec des roues abrasives comme des machines de coupe sont traitées dans l'IEC 62841-2-22. The rated voltage is not more than 250 V for single-phase a.c. or d.c. tools, and 480 V for three-phase a.c. tools. The rated input is not more than 3 700 W. The limits for the applicability of this standard for battery tools is given in Annex K. This standard deals with the hazards presented by tools which are encountered by all persons in the normal use and reasonably foreseeable misuse of the tools. Les outils électroportatifs, qui peuvent être montés sur un support de travail pour être utilisés comme outils installés à poste fixe sans aucune modification de l'outil lui-même, sont compris dans le domaine d'application de la présente Norme et la combinaison d'un outil portatif et d'un support est considérée comme un outil portable, donc couvert par la Partie 3 applicable. 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 12 mois et au plus tard 36 mois après la date de publication. Mots-clés: Scie, Circulaire, Coupant
Cette publication doit être lue conjointement avec la CEI 62841-1:2014.
