24、 national standards shall be withdrawn at the latest by April 2002. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of EC Directive(s).

29、essential safety requirements of the Machinery Directive, and associated EFTA regulations. This European Standard is a type “C” standard as defined in EN 292-1 : 1991. The extent to which hazards are covered is indicated in the scope of this European Standard. The requirements of this European Stand
30、ard concern designers, manufacturers, suppliers and importers of single blade edging circular rip sawing machines with power driven saw unit and manual loading and/or unloading. This European Standard also includes information to be provided by the manufacturer to the user. Common requirements for t
31、ooling are given in EN 847-1 : 1997. 1 Scope This European Standard sets out the requirements and/or the measures to remove the hazards and/or limit the risk on single blade edging circular rip sawing machines with power driven saw unit and manual loading and/or unloading, hereinafter referred to as
32、 “machines”, designed to cut solid wood, chipboard, fibreboard and plywood. This European Standard covers the hazards relevant to these machines as stated in clause 4. For Computer Numerically Controlled (CNC) machines this European Standard does not cover hazards related to Electro-Magnetic Compati
33、bility (EMC). This European Standard applies to machines where the workpiece is stationary, the vertical and horizontal movements of the saw unit are power driven, and where the machine is provided with workpiece clamping the workpiece may or may not be clamped during cutting. This European Standard
34、 does not apply to machines : ? where the workpiece is fed to the sawblade during cutting; ? designed specifically for cutting veneers; ? provided with a device situated behind the line of cut, which moves in a direction parallel to the line of cut, for automatically unloading the workpiece during t
35、he return of the saw unit to the rest position. This European Standard is primarily directed at machines which are manufactured after the date of issue of this European Standard. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publicati
36、ons. These normative references are cited at the appropriate places in the text, and the publications are listed hereafter. For dated references subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or revision. F
