IEC 60745-2-5:2010

Hand-held motor-operated electric tools - Safety - Part 2-5: Particular requirements for circular saws

IEC 60745-2-5:2010 deals with the safety of hand-held motor-operated or magnetically driven electric tools, specific requirements for all types of circular saws. The rated voltage being not more than 250 V for single-phase a.c. or d.c., and 440 V for three-phase a.c. tools. This standard does not apply to saws used with abrasive wheels. The principal changes in this edition as compared with the fourth edition are as follows:
- clause 17 introduction of endurance tests in practical use for the guards of all types of saws;
- clause 19 clarifications and editorial improvements in respect to the guarding;
- annex M editorial improvements.
This publication is to be read in conjunction with  IEC 60745-1:2006.

Outils électroportatifs à moteur - Sécurité - Partie 2-5: Règles particulières pour les scies circulaires

La CEI 60745-2-5:2010 traite de la sécurité des outils électriques portatifs à moteur ou à entraînement magnétique, exigences spécifiques pour tous les types de scies circulaires. La tension assignée n'étant pas supérieure à 250 V pour les outils monophasés alimentés en courant alternatif ou pour les outils alimentés en courant continu, et 440 V pour les outils triphasés alimentés en courant alternatif. La présente norme ne s'applique pas aux scies utilisées avec des roues abrasives. Les principales modifications par rapport à l'édition précédente sont:
- article 17, introduction des essais d'endurance dans la pratique, pour les protecteurs de tous les types de scies;
- article 19, clarifications et amélioration d'ordre rédactionnel en ce qui concerne la protection;
- annexe M, améliorations d'ordre rédactionnel.
Cette publication doit être lue conjointement avec la CEI 60745-1:2006.
