Safety of woodworking machines - Circular sawing machines - Part 12: Pendulum cross-cut sawing machines

This document deals with the significant hazards, hazardous situations and events as listed in Clause 4 which are relevant to pendulum cross-cut sawing, herein after referred to as 'machines', designed to cut solid wood, chipboard, fibreboard, plywood and also these materials when covered with plastic edging and/or plastic/light alloy laminates.
Any workpiece positioning equipment fitted to the machine is included in this European Standard.  
This European Standard does not apply to:
a)   machines for cross cutting logs;
b)   machines where the saw unit can be rotated about a horizontal axis.
For Computer Numerically Controlled (CNC) machines this European Standard does not cover the hazards related to Electro-Magnetic Compatibility (EMC).
NOTE    The requirements of this European Standard apply to all machines whatever their method of control e.g. electromechanical and/or electronic.
This European Standard is primarily directed at machines which are manufactured after the date of publication by CEN.

!Dieses Dokument behandelt alle im Abschnitt 4 aufgeführten signifikanten Gefährdungen, Gefährdungssituationen
und Gefährdungsereignisse, die auf Pendelkreissägemaschinen zutreffen — im Folgenden als
„Maschinen“ bezeichnet —, die konstruiert sind zum Schneiden von Massivholz, Spanplatten, Faserplatten
oder Sperrholz sowie diesen Werkstoffen, wenn sie mit Kunststoffkanten versehen sind und/oder Beschichtungen
aus Kunststoff/Leichtmetall-Legierung haben."
Jegliche Einrichtung zum Positionieren des Werkstückes, die an der Maschine angebaut ist, ist in dieser
Europäischen Norm mit behandelt.
!gestrichener Text"
Diese Europäische Norm gilt nicht für:
a) Maschinen zum Querschneiden von Rundholz;
b) Maschinen, bei denen das Sägeaggregat um eine waagrechte Achse gedreht werden kann.
Diese Europäische Norm behandelt bei CNC-Maschinen nicht die Gefährdungen im Zusammenhang mit der
elektromagnetischen Verträglichkeit (EMV).
ANMERKUNG Die Anforderungen dieser Europäischen Norm gelten für alle Maschinen unabhängig von der Art ihrer
Steuerung, z. B. elektromechanisch und/oder elektronisch.
Diese Europäische Norm gilt in erster Linie für Maschinen, die hergestellt wurden, nachdem CEN diese
Europäische Norm veröffentlichte.

Sécurité des machines pour le travail du bois - Machines à scies circulaires - Partie 12: Tronçonneuses pendulaires

!Le présent document traite des phénomènes, des situations et des événements dangereux significatifs tels
qu’énumérés à l’Article 4, applicables aux tronçonneuses pendulaires, ci-après désignées «machines», conçues pour
la coupe de bois massif, de panneaux de particules, de panneaux de fibres, de contre-plaqué, ainsi que ces
matériaux lorsque leurs surfaces ou leurs chants sont recouverts de matière plastique et/ou de plastique/alliage léger
L'équipement, fixé sur la machine, permettant le positionnement de la pièce à travailler est inclus dans la présente
Norme européenne.
!texte supprimé"
La présente norme ne s'applique pas aux :
a) machines conçues pour le tronçonnage de grumes ;
b) machines dont l'unité de sciage peut pivoter autour d'un axe horizontal.
Pour les machines à commande numérique (CN), la présente Norme européenne ne traite pas des phénomènes
dangereux liés à la compatibilité électromagnétique (CEM).
NOTE Les prescriptions de la présente norme s’appliquent à toutes les machines quelle que soit leur méthode de
commande, par exemple : électromécanique et/ou électronique.
La présente Norme européenne est applicable avant tout aux machines fabriquées après la date de publication de la
présente Norme européenne.
