La présente Norme européenne, considérée conjointement à l'EN ISO 4254-1, traite de tous les phénomènes dangereux, situations dangereuses et événements dangereux significatifs (tels qu'énumérés dans le Tableau 1) pertinents pour les pelles rétros hydrauliques montées sur l'attelage trois points d'un tracteur, lorsqu'elles sont utilisées normalement et dans les conditions de mauvaise utilisation prévisibles par le fabricant. La présente Norme européenne n’est pas applicable aux opérations pour déplacer les charges unitaires avec crochet ou autre dispositif similaire. Les matériaux liés aux activités d’excavation ne sont pas considérés comme des charges unitaires et leur déplacement est couvert par la présente norme. La présente norme ne donne pas de prescription pour les dispositifs d’attache rapide. NOTE 1 Un amendement à l’EN 474-1 est en préparation pour traiter de cet aspect. Il sera examiné pour une inclusion dans la présente norme. NOTE 2 Les prescriptions particulières relatives à la réglementation routière ne sont pas prises en compte dans la présente Norme européenne. La présente Norme européenne ne s'applique pas aux pelles rétro hydrauliques fabriquées avant la date de publication du présent document par le CEN.
