Le présent document traite de tous les phénomènes dangereux, situations et événements dangereux significatifs tels qu’énumérés à l’Article 4, applicables aux perceuses, aux défonceuses et aux perceuses/défonceuses à commande numérique (telles que définies en 3.2.1) désignées ci-après sous le terme « machines », celles-ci sont conçues pour usiner du bois, des panneaux de fibres ou de particules, de contreplaqué ainsi que ces matériaux lorsque leurs surfaces ou leurs chants sont recouverts de plastique ou de plaquage, durant l’utilisation normale et dans les conditions prévues par le fabricant.
Le présent document est applicable aux machines équipées :
a)   d’unités supplémentaires de sciage, de ponçage, de plaquage sur chant ;
b)   de support de pièce fixe ou mobile ;
c)   de serrage de pièce mécanique, hydraulique, pneumatique ou par dépression ;
d)   de dispositifs de changement automatique d’outils.
Le présent document ne traite pas des phénomènes dangereux spécifiques aux unités de plaquage sur chant montées sur les perceuses, les défonceuses et les perceuses/défonceuses à commande numérique.
Le présent document ne s'applique qu’aux perceuses, défonceuses et perceuses/défonceuses à commande numérique conçues pour utiliser des fraises ayant un diamètre de coupe en dessous de 16 mm, ou des fraises ou des lames conformes à l'EN 847-1:2005 et à l’EN 847-2:2001, et des forets ainsi que des roues de ponçage.
Le présent document ne s'applique pas aux perceuses, défonceuses et perceuses/défonceuses à commande numérique conçues pour utiliser des meules.
Le présent document ne s'applique pas aux défonceuses monobroche à avance manuelle ou mécanisée.
NOTE   Les défonceuses monobroche à avance manuelle ou mécanisée sont traitées dans l’EN 848-2:2007.
