Celles-ci sont conçues pour la coupe de bois massif, de panneaux de particules ou de fibres, de contreplaqué ainsi que ces matériaux lorsque leurs surfaces ou leurs chants sont recouverts de matière plastique ou d’un stratifié de plastique, durant l’utilisation normale et dans les conditions prévues par le fabricant.
NOTE 1 Pour la définition d’une machine fixe et d’une machine déplaçable, voir 3.12 et 3.13.
NOTE 2 Les prescriptions spécifiques concernant une unité d’alimentation mécanisée escamotable sera prise en compte lors de la prochaine révision.
Le présent document ne s’applique pas :
- aux machines combinées composées uniquement d’une unité de dégauchissage et d’une unité de rabotage,
NOTE 3 Les machines combinées composées uniquement d’une unité de dégauchissage et d’une unité de rabotage sont traitées dans l’EN 861:2007.
- aux machines combinées avec une scie à ruban,
- aux machines-outils électriques combinées semi-fixes, ou à toute adaptation permettant leur utilisation de manière différente, c’est-à-dire fixées sur un établi,
NOTE 4 Les machines-outils électriques semi-fixes combinées sont couvertes par les prescriptions des normes EN 61029-1:2000 et EN 61029-2-11:2003.
