This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by May 2018,
23、 and conflicting national standards shall be withdrawn at the latest by May 2018. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN shall not be held responsible for identifying any or all such patent rights. This document super
24、sedes EN 847-1:2013. According to the CEN-CENELEC Internal Regulations, the national standards organisations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of M

BS EN 8471:2017EN 847-1:2017 (E) 4 Introduction The extent
26、 to which hazards are covered is indicated in the scope of this document. The requirements of this document concern designers, manufacturers, suppliers and importers of tools for cutting wood and materials with similar physical characteristics to wood. This document also includes information that th
27、e manufacturer will provide to the user. BS EN 8471:2017EN 847-1:2017 (E) 5 1 Scope This European Standard specifies all hazards arising from the use 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
28、information. This European Standard deals with milling tools (bore mounted, shank mounted) and circular saw blades, designed for chip removal machining (cutting) of wood and materials with similar physical characteristics to wood, hereinafter referred to as “tools”. The hazards are listed in Clause
29、4. This European Standard does not cover any hazard related to the strength of shank of shank mounted milling tools. 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
30、 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. This European Standard is not applicable for tools according to this scope, which are manufactured before th
31、e date of its publication. NOTE For woodworking machines and materials with similar physical characteristics to wood, see ISO 19085-1. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated
32、 references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.
