NF EN 836+A4

Le présent document, préparé dans le but de donner des moyens de se conformer aux exigences essentielles de la Directive Machines (89/392/CEE modifiée par les Directives 91/368/CEE, 93/44/CEE et 93/68/CEE), détermine les prescriptions de sécurité et les vérifications pour la conception et la construction des tondeuses à moteur à axe vertical et à cylindre de coupe, des tracteurs pour pelouses et jardins avec équipements de tonte adaptable, qu'ils soient à usage professionnel ou non.

Le présent document modifie le paragraphe 4.2.1.3.2.3 "Mesure du temps d'arrêt des lames" de la norme NF EN 836:1997 en précisant la méthode d'essai à utiliser.

Le présent amendement vient en réponse à la note du domaine d'application de la norme NF EN 836 : il la complète par des prescriptions destinées à réduire les niveaux de vibrations et de bruittransmis à l'opérateur. Il offre par ailleurs des méthodes d'essai permettant d'évaluer ces niveaux vibratoire et sonore.

Le présent document donne des prescriptions complémentaires au 4.2.2 et à l'annexe E sur les spécifications du carton utilisé pour la construction des panneaux-cibles lors de l'essai de projection d'objets ; il introduit en annexe B un pictogramme lié à la maintenance et apporte des modifications rédactionnelles et des clarifications à l'ensemble du texte. Il est à noter que l'amendement exclut explicitement du domaine d'application les tondeuses électriques et alimentées par batteries.

ISO 5395-1:2013 specifies terminology and common test methods used for verification of safety requirements for combustion engine powered rotary lawnmowers and cylinder lawnmowers including pedestrian-controlled (with or without sulky) and ride-on types (hereafter named "lawnmower"), and equipped with: metallic cutting means and/or; non-metallic cutting means with one or more cutting elements pivotally mounted on a generally circular drive unit, where these cutting elements rely on centrifugal force to achieve cutting, and have a kinetic energy for each single cutting element of 10 J or more. It does not apply to: robotic and remote-controlled lawnmowers, flail mowers, grassland mowers, sickle bar mowers, towed/semi-mounted grass cutting machines, and scrub-clearing machines; cutting-means assembly when used in combination with an agricultural tractor; electrically powered and battery-powered lawnmowers. Note that IEC 60335-1 together with IEC 60335-2-77, give requirements for pedestrian-controlled walk-behind electrically powered lawnmowers. ISO 5395-1:2013 is not applicable to lawnmowers which are manufactured before the date of publication of this document.

ISO 5395-2:2013 specifies safety requirements and their verification for combustion-engine-powered pedestrian-controlled (with or without sulky) rotary lawnmowers and cylinder lawnmowers (hereafter named "lawnmower"), and equipped with: metallic cutting means; and/or non-metallic cutting means with one or more cutting elements pivotally mounted on a generally circular drive unit, where these cutting elements rely on centrifugal force to achieve cutting, and have a kinetic energy for each single cutting element of 10 J or more. It does not apply to: robotic and remote-controlled lawnmowers, flail mowers, grassland mowers, sickle bar mowers, towed/semi-mounted grass-cutting machines, and scrub-clearing machines; electrically powered and battery-powered lawnmowers; pedestrian-controlled lawnmowers with a swing-over handle. Note that IEC 60335-1 together with IEC 60335-2-77 give requirements for pedestrian-controlled walk-behind electrically powered lawnmowers. ISO 5395-2:2013 deals with all significant hazards, hazardous situations or events relevant to lawnmowers when used as intended and under the conditions of misuse which are reasonably foreseeable by the manufacturer. It is not applicable to lawnmowers which are manufactured before the date of publication of this document.

ISO 5395-3:2013 specifies safety requirements and their verification for combustion-engine-powered ride-on (seated) rotary lawnmowers and cylinder lawnmowers (hereafter named "lawnmower"), and equipped with: metallic cutting means; and/or non-metallic cutting means with one or more cutting elements pivotally mounted on a generally circular drive unit, where these cutting elements rely on centrifugal force to achieve cutting, and have a kinetic energy for each single cutting element of 10 J or more. It does not apply to: robotic and remote-controlled lawnmowers, flail mowers, grassland mowers, sickle bar mowers, towed/semi-mounted grass-cutting machines, and scrub-clearing machines; cutting-means assembly when used in combination with an agricultural tractor; electrically powered and battery-powered lawnmowers. ISO 5395-3:2013 deals with all significant hazards, hazardous situations or events relevant to lawnmowers when used as intended and under the conditions of misuse which are reasonably foreseeable by the manufacturer. It is not applicable to lawnmowers which are manufactured before the date of publication of this document.
