34、sential safety requirements of the Machinery Directive, and associated EFTA regulations. This document is a type “C” standard as defined in EN ISO 12100:2010. The machinery concerned and the extent to which hazards, hazardous situations and events covered are indicated in the scope of this document.

35、 The requirements of this document are directed to manufacturers and their authorised representatives of single blade edging circular rip sawing machines with power driven saw unit and manual loading and/or unloading. This document is also useful for designers and importers. When provisions of this

36、type C standard are different from those which are stated in type A or B standards, the provisions of this type C standard take precedence over the provisions of other standards, for machines that have been designed and built according to the provisions of this type C standard. This document also in

37、cludes information to be provided by the manufacturer to the user. Common requirements for tooling are given in EN 847-1:2005+A1:2007. BS EN 1870-8:2012EN 1870-8:2012 (E) 7 1 Scope This European Standard deals with all significant hazards, hazardous situations and events as listed in Clause 4 which

38、are relevant to single blade edging circular rip sawing machines with power driven saw unit and manual loading and/or unloading, hereinafter referred to as “machines”, designed to cut solid wood, chipboard, fibreboard and plywood when they are used as intended and under the conditions foreseen by th

39、e manufacturer including reasonably foreseeable misuse. This document 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 duri

40、ng cutting. This document does not apply to machines: where the workpiece is fed to the saw blade during cutting; designed 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 du

41、ring the return of the saw unit to the rest position. This document is not applicable to machines manufactured before its date of publication as EN. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its applicat
