Ausgenommen vom Anwendungsbereich ist die Beschickungseinrichtung. Nicht behandelt werden Gefährdungen durch Überdruck.
ANMERKUNG   Für Gefährdungen durch Überdruck siehe die Richtlinie über Druckgeräte.
Diese Europäische Norm gilt nicht für Holzschleifer, die hergestellt wurden, bevor CEN diese Europäische Norm veröffentlichte.

Sécurité des machines - Prescriptions de sécurité pour la conception et la construction de machines de fabrication et de finition du papier - Partie 22: Défibreurs

La présente norme européenne s’applique aux défibreurs destinés à obtenir de la pâte de bois dans la
fabrication du papier, y compris le dispositif d'affûtage, et doit être utilisée conjointement avec
l'!EN 1034-1:2000+A1:2009". Elle traite tous les phénomènes dangereux significatifs, les situations
dangereuses et les évènements dangereux qui s'appliquent aux défibreurs lorsqu'ils sont utilisés dans des conditions
normales et conformément aux conditions prévisibles du fabricant (voir Article 4). La présente norme ne s'applique
pas au dispositif d'alimentation et ne traite pas non plus des phénomènes dangereux engendrés par la surpression.
NOTE Pour les phénomènes dangereux engendrés par la surpression, voir la directive relative aux appareils à pression.
La présente norme européenne ne s'applique pas aux défibreurs qui ont été fabriqués avant sa publication
par le CEN.
