This European Standard shall be given the status of a national standard, either by publication of an identical
15、text or by endorsement, at the latest by December 1999, and conflicting national standards shall be withdrawn at the latest by December 1999. This European Standard has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essenti
16、al requirements of EU Directive(s). For relationship with EU Directive(s), see informative Annex ZA, which is an integral part of this standard. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Sta
17、ndard: Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and the United Kingdom. Organizations contributing to the preparation of this European Standard include the European Manu

EN 1870-2:1999 BSI 6 January 2003 3 0 Introduction This European Standard has been prepared
22、 to be a harmonized standard to provide one means of conforming to the 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 sc
23、ope of this European Standard. The requirements of this European Standard concern designers, manufacturers, suppliers and importers of horizontal beam panel saws and vertical panel saws. This standard also includes information to be provided by the manufacturer to the user. 1 Scope This European Sta
24、ndard specifies the requirements and/or measures to remove the hazards and limit the risks on manually loaded and/or unloaded horizontal beam panel saws and vertical panel saws hereinafter referred to as “ machines” , designed to cut solid wood, chipboard, fibreboard, plywood and also these material
25、s where they are covered with plastics edging and/or plastics/light alloy laminates. This European Standard covers all the hazards relevant to this machine. These hazards are listed in Clause 4. This European Standard does not cover machines intended only for ripping solid wood or machines where the
26、 workpiece is moved during the cutting process, or machines specifically designed for cutting veneers. This European Standard does not apply to hand-held woodworking machines or any adaptation permitting their use in a different mode, i.e. bench mounting. For Computer Numerically Controlled (CNC) ma
27、chines, this European Standard does not cover the hazards related to Electromagnetic Compatibility (EMC) as stated in the EMC Directive 89/336/EEC dated 3-5-89. This European Standard is primarily directed at machines which are manufactured after the date of issue of this standard. NOTEMachines cove
28、red by this standard are listed under Annex IV, Clause A.1.4 of the Machinery Directive. 2 Normative references This European Standard incorporates by dated or undated reference provisions from other publications. These normative references are cited at the appropriate places in the text and the pub
29、lications 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.

45、ng panels 3.2 horizontal beam panel saw panel saw where the workpiece is supported in the horizontal plane during cutting. The saw unit is mounted below the workpiece, and the cutting stroke is power driven. Before the cutting stroke commences, the sawblade is automatically raised through a slot in
46、the worktable and is retracted from the workpiece for the return stroke. Machines are fitted with a pressure beam which holds the workpiece in position during the cut, and are designed to cut in a single straight line only (see Figure 1) 3.3 vertical panel saw panel saw where the workpiece is supported in a near vertical plane during cutting see Figure 2a) and Figure 2b) Figure 1 Example of horizontal beam panel saw ?
