36、 This document has been prepared to be a harmonised standard to provide one means of conforming to the essential 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 exte

37、nt to which hazards, hazardous situations and events covered are indicated in the scope of this document. When provisions of this type C standard are different from those which are stated in type A or B standards, the provisions of this C type standard take precedence over the provisions of other st

38、andards, for machines that have been designed and built according to the provisions of this type C standard. The requirements of this document are directed to manufacturers and their authorised representatives of semi-automatic horizontal cutting cross-cut sawing machines with one saw unit (radial a

39、rm saws). It is also useful for designers. This document also includes examples of information which can be provided by the manufacturer to the user. Common requirements for tooling are given in EN 847-1:2013. Copyright European Committee for Standardization Provided by IHS under license with CENNot

41、ss-cut sawing machines with one saw unit (radial arm saws), hereinafter referred to as “machines”, designed to cut solid wood, chipboard, fibreboard, plywood and also these materials when covered with plastic edging and/or plastic/light alloy laminates when they are used as intended and under the co

42、nditions foreseen by the manufacturer including reasonably foreseeable misuse. Machines which are designed to work wood based materials may also be used for working rigid plastic materials with similar physical characteristics as wood. Any work-piece positioning equipment fitted to the machine is in

43、cluded in this European Standard. This European Standard does not apply to machines: a) with manual feed of the saw unit; or b) for cross cutting logs; or c) specifically designed for sawing and/or milling roof timber frames; or d) fitted with hydraulic braking systems. NOTE 1 Radial arm saws with m

44、anual feed of the saw unit (the saw unit is moved by hand) are dealt with in EN 1870-17:2012 and EN 61029-2-2:2009. NOTE 2 The requirements of this European Standard apply to all machines whatever their method of control, e.g. electromechanical and/or electronic. This European Standard is not applic

45、able to machines which are manufactured before the date of its publication as EN. NOTE 3 Machines covered by this European Standard are listed under 1.4 of Annex IV of the Machinery Directive. 2 Normative references The following documents, in whole or in part, are normatively referenced in this doc
