AVANT-PROPOS
1) La CEI (Commission Électrotechnique Internationale) est une organisation mondiale de normalisation
composée de l'ensemble des comités électrotechniques nationaux (Comités nationaux de la CEI). La CEI a
pour objet de favoriser la coopération internationale pour toutes les questions de normalisation dans les
domaines de l'électricité et de l'électronique. A cet effet, la CEI, entre autres activités, publie des Normes
internationales. Leur élaboration est confiée à des comités d'études, aux travaux desquels tout Comité national
intéressé par le sujet traité peut participer. Les organisations internationales, gouvernementales et non
gouvernementales, en liaison avec la CEI, participent également aux travaux. La CEI collabore étroitement
avec l'Organisation Internationale de Normalisation (ISO), selon des conditions fixées par accord entre les
deux organisations.
2) Les décisions ou accords officiels de la CEI concernant les questions techniques représentent, dans la mesure
du possible, un accord international sur les sujets étudiés, étant donné que les Comités nationaux intéressés
sont représentés dans chaque comité d’études.
3) Les documents produits se présentent sous la forme de recommandations internationales. Ils sont publiés
comme normes, spécifications techniques, rapports techniques ou guides et agréés comme tels par les
Comités nationaux.
4) Dans le but d'encourager l'unification internationale, les Comités nationaux de la CEI s'engagent à appliquer de
façon transparente, dans toute la mesure possible, les Normes internationales de la CEI dans leurs normes
nationales et régionales. Toute divergence entre la norme de la CEI et la norme nationale ou régionale
correspondante doit être indiquée en termes clairs dans cette dernière.
5) La CEI n’a fixé aucune procédure concernant le marquage comme indication d’approbation et sa responsabilité
n’est pas engagée quand un matériel est déclaré conforme à l’une de ses normes.
6) L’attention est attirée sur le fait que certains des éléments de la présente Norme internationale peuvent faire
l’objet de droits de propriété intellectuelle ou de droits analogues. La CEI ne saurait être tenue pour
responsable de ne pas avoir identifié de tels droits de propriété et de ne pas avoir signalé leur existence.
La présente partie de la Norme internationale CEI 60745 a été établie par le sous-comité 61F,
Sécurité des outils électroportatifs à moteur, du comité d’études 61 de la CEI: Sécurité des
appareils électrodomestiques et analogues.
Cette version bilingue, publiée en 2003-03, correspond à la version anglaise.
Le texte anglais de cette norme est issu des documents 61F/483/FDIS et 61F/504/RVD. Le
rapport de vote 61F/504/RVD donne toute information sur le vote ayant abouti à l’approbation
de cette norme.
La version française de cette norme n’a pas été soumise au vote.
Cette publication a été rédigée selon les Directives ISO/CEI, Partie 2.
