Tools for woodworking - Safety requirements - Part 1: Milling tools, circular saw blades
This document specifies all hazards arising from the design of tools for woodworking machines, and describes the methods for the elimination or reduction of these hazards by tool design and by the provision of information. This document deals with milling tools (bore mounted, shank mounted, integrated spindle) and circular saw blades, but does not cover any hazard related to the strength of shank of shank mounted milling tools. The hazards are listed in Clause 5. This document does not apply to boring bits, eccentric single router cutters, cutters with cutting circle less than 16 mm and to tools used in rotary knife lathes and copying lathes where the hazard of ejection and contact with the tool is always prevented by a system of fixed guards and/or movable guards interlocked with guard-locking and/or self-closing guards.
Maschinen-Werkzeuge für Holzbearbeitung - Sicherheitstechnische Anforderungen - Teil 1: Fräs- und Hobelwerkzeuge, Kreissägeblätter
Dieses Dokument gilt für alle Gefährdungen, die aufgrund der Gestaltung von Werkzeugen für Holzbearbeitungs¬maschinen entstehen und legt die Verfahren für die Beseitigung oder Verringerung dieser Gefährdungen durch die Gestaltung des Werkzeuges und durch die Bereitstellung von Informationen fest. Dieses Dokument behandelt Fräs¬werkzeuge (mit Bohrung, mit Schaft, mit eingebauter Messerwelle) und Kreissägeblätter, jedoch sind Gefährdungen in Verbindung mit der Schaftfestigkeit von Fräswerkzeugen mit Schaft nicht einbezogen. Die Gefährdungen sind in Abschnitt 5 aufgeführt. Dieses Dokument gilt nicht für Bohrer, einschneidige Schaftfräser für exzentrische Spannung, Fräser mit einem Schneidenkreis von weniger als 16 mm und für Werkzeuge in Drehmaschinen mit rotierendem Werkzeug und Kopierdrehmaschinen, bei denen einer Gefährdung durch Herausschleudern oder durch Kontakt mit dem Werkzeug stets durch ein System von feststehenden und/oder beweglichen Schutzvorrichtungen mit Zuhaltung und/oder mit selbstschließenden Schutzvorrichtungen vorgebeugt wird.
Outils pour le travail du bois - Exigences de sécurité - Partie 1: Outils de fraisage, lames de scies circulaires
La présente norme est applicable à tous les phénomènes dangereux résultant de la conception des outils pour machines à bois et décrit des méthodes de conception des outils ainsi que des procédures d'information permettant d'éliminer ou de réduire ces phénomènes dangereux. La Partie 1 de la présente norme traite des outils de fraisage (à trou, à queue et à broche intégrée) et des lames de scies circulaires, mais ne couvre pas les phénomènes dangereux liés à la résistance de la queue des outils de fraisage à queue. La liste des phénomènes dangereux est donnée à l'article 5. La présente norme ne s'applique pas aux mèches à percer, aux fraises pour défonceuses à lame unique pour utilisation sur mandrin excentrique, aux fraises ayant un diamètre de coupe inférieur à 16 mm ni aux outils utilisés sur des tours rotatifs et des tours à copier où un système de protecteurs fixes et/ou mobiles interverrouillés et/ou de protecteurs à fermeture automatique est utilisé pour éviter le risque de projection et de contact avec l'outil.

does not cover any hazard related to the strength of shank of shank mounted milling tools. The hazards are listed in
Clause 5. This document does not apply to boring bits, eccentric single router cutters, cutters with cutting circle less
