BS EN 847-1:2013EN 847-1:2013 (E) 5 Introduction The extent to which hazards are covered is indicated in the Scope of this document. The requirements of this document concern designers, manufacturers, suppliers and impo
25、rters of tools for woodworking. This document also includes information which the manufacturer will provide to the user. BS EN 847-1:2013EN 847-1:2013 (E) 6 1 Scope This European Standard specifies all hazards arising from the use of tools for woodworking machines, and describes the methods for the
26、elimination or reduction of these hazards by tool design and by the provision of information. This European Standard deals with milling tools (bore mounted, shank mounted), integrated tools and circular saw blades. This European Standard does not cover any hazard related to the strength of shank of
27、shank mounted milling tools. The hazards are listed in Clause 4. This European Standard 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 wit
28、h the tool is always prevented by a system of fixed guards and/or movable guards interlocked with guard-locking and/or self-closing guards. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

32、 thicknessing cutter) normally having its main feed direction perpendicular to the rotation axis, for working various surfaces on wood and similar materials through chip removal Note 1 to entry: The cutting edge of the cutting part may be parallel to the axis of rotation, square to the axis of rota
33、tion, or a profile which is a combination of the two. The tool may be a one piece tool, a composite tool, BS EN 847-1:2013EN 847-1:2013 (E) 7 a complex tool, or in the form of a tool set. 3.1.2 circular saw blade rotating cutting tool for cross-cutting or ripping wood and similar materials through c
34、hip removal Note 1 to entry: The tools cut on the periphery and on both flanks simultaneously, and may be a one piece tool, a composite tool, or a complex tool. 3.1.3 one piece tool (solid tool) tools without bonded or detachable parts: the body and the cutting parts are one piece 3.1.4 composite to
35、ol (tipped tool) tools where the cutting parts (tips) are firmly connected by bonding to the body, e.g. welding, brazing, adhesive fixing 3.1.5 complex tool tools where one or more cutting parts (inserts, blades) are exchangeably mounted in a body through detachable fixing elements Note 1 to entry:
