Garden equipment - Integrally powered shredders/chippers - Safety
This European Standard specifies safety requirements and their verification for the design and construction of hand fed, shredders/chippers with integral power source and with or without vacuum assisted collection which are designed primarily to reduce organic material to smaller pieces. It is only applicable to shredders/chippers that are designed for use outdoors in a stationary position by an operator standing on the ground. It applies to shredders/chippers with feed intake openings in the form of a single opening or an opening divided into a number of segments. The feed intake openings or segments each being of any shape that will fit into a square of 250 mm - 250 mm measured at the relevant safety distance to the cutting means.
NOTE Feed safety openings are limited to 250 mm - 250 mm but the total feed intake opening can be any size.
This standard describes methods of elimination or reduction of hazards arising from the use of shredders/chippers. In addition it specifies the type of information to be provided by the manufacturer on safe working practices.
This standard does not cover requirements for:
- units driven by an external power source;
- mobile use of units which can be used in both stationary and mobile modes;
- units with powered discharge intended to broadcast material or load vehicles;
- units with mechanically powered feed intake or attachments;
- units with cutting means of either one or more non-metallic filaments, or one or more non-metallic cutting elements pivotally mounted on a generally circular central drive unit, where these cutting elements rely on centrifugal force to achieve cutting, and have a kinetic energy for each single cutting means of less than 10 J;
- electrical aspects of electrically driven shredders.
Environmental hazards and EMC have not been considered in this standard.
This standard deals with all significant hazards, hazardous situations and events relevant to shredders/chippers, when they are used as intended

mit Einwurföffnungen in Form einer einzelnen Öffnung oder einer in Segmenten unterteilten Öffnung. Die
Einwurföffnungen bzw. Segmente müssen jeweils so geformt sein, dass sie eine Fläche von
250 mm × 250 mm, gemessen vom relevanten Sicherheitsabstand zum Schneidwerkzeug, aufweisen.
ANMERKUNG Die Einwurfsicherheitsöffnungen sind auf 250 mm × 250 mm begrenzt, die Größe der gesamten
Einwurföffnung ist unbeschränkt.
Diese Norm beschreibt Verfahren zur Eliminierung oder Reduzierung von Gefährdungen, die sich aus dem
Gebrauch von Schreddern/Zerkleinerern ergeben. Außerdem legt sie die Art von Informationen fest, die der
Hersteller für den sicheren Gebrauch bereitstellen muss.
Diese Norm enthält keine Anforderungen für:
von einer externen Energiequelle angetriebene Einheiten;
den mobilen Einsatz von Einheiten, die sowohl mobil als auch stationär verwendet werden können;
Einheiten mit motorgetriebenem Auswurf zum Ausstreuen von Material oder zum Beladen von Fahrzeugen;
Einheiten mit mechanisch angetriebenem Einzug oder Anbauten;
Einheiten mit ein oder mehreren nicht metallischen Fäden, oder mit ein oder mehreren nicht metallischen
Schneidelementen, schwenkbar montiert auf eine im Allgemeinen kreisförmige zentrale Antriebseinheit,
wo diese Schneidelemente durch zentrifugale Kraft schneiden und die kinetische Energie für jedes
einzelne Schneidwerkzeug unter 10 J beträgt;
elektrische Aspekte von elektrisch getriebenen Zerkleinerern;
die Gefährdung der Umwelt und EMV wird in dieser Norm nicht in Betracht gezogen.
Matériel de jardinage - Broyeurs/déchiqueteurs à moteur integré - Sécurité
La présente Norme européenne spécifie les prescriptions de sécurité et leurs vérifications pour la conception et la construction des broyeurs/déchiqueteurs à chargement manuel avec une source de puissance incorporée, munis ou non d'un système de ramassage par aspiration, qui sont conçus principalement pour réduire les matières organiques en morceaux plus petits. Elle s’applique à des broyeurs/déchiqueteurs qui sont conçus pour une utilisation à l’extérieur en position fixe par un utilisateur se tenant debout sur le sol. Elle s'applique aux broyeurs/déchiqueteurs munis d'ouvertures de prise d’alimentation formées d'une seule ouverture ou d'une ouverture divisée en segments. Les ouvertures ou les segments de prise d’alimentation ont chacun une forme quelconque pouvant s'inscrire dans un carré de 250 mm x 250 mm mesuré à la distance de sécurité appropriée de l’organe de coupe.
NOTE Les ouvertures d’alimentation de sécurité sont limitées à 250 mm x 250 mm mais l’ouverture de prise d’alimentation totale peut être de n’importe quelle dimension.
La présente norme décrit les méthodes pour éliminer ou réduire les phénomènes dangereux inhérents à l'utilisation des broyeurs/déchiqueteurs. En outre, elle spécifie le type d'informations que le fabricant doit fournir sur les pratiques d’utilisation sûre.
La présente norme ne traite pas des prescriptions applicables à :
- des machines alimentées par une source de puissance externe ;
- une utilisation mobile d’unités qui peuvent être utilisées à la fois en mode fixe et mobile ;
- des machines munies d’une éjection à moteur destinée à répandre le matériau ou à charger des véhicules ;
