BS EN 1870-18:2013EN 1870-18:2013 (E) 6 Introduction This document has been prepared to be a harmonised standard to provide one means of conforming to the essent

33、ial 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 are covered are indicated in the scope of this document.

34、When provisions of this 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 standar

35、d. The requirements of this document are directed to manufacturers and their authorised representatives of dimension saws. They are also useful for designers. This document also includes provisions and examples of information to be provided by the manufacturer to the user. Common requirements for to

36、oling are given in EN 847-1:2005+A1:2007. BS EN 1870-18:2013EN 1870-18:2013 (E) 7 1 Scope This European Standard deals with all significant hazards, hazardous situations and events as listed in Clause 4 which are relevant to stationary and displaceable dimensions saws, hereinafter referred to as “ma

37、chines”, designed to cut solid wood, chipboard, fibreboard, plywood and also these materials, if they are covered with plastic edging and/or plastic/light alloy laminates, when they are used as intended and under the conditions foreseen by the manufacturer including reasonably foreseeable misuse. Ma

38、chines which are designed to work wood based materials may also be used for working rigid plastic materials with similar physical characteristics as wood. The machine may have any of the following features: a) facility for the saw blade and scoring saw blade (if any) to be raised and lowered; b) fac

39、ility to tilt the main saw blade and scoring saw blade (if any) for angled cutting; c) facility for scoring; d) facility for grooving with milling tool; e) demountable power feed unit; f) post-formed edge pre-cutting unit; g) power operated sliding table; h) workpiece clamping. NOTE 1 For the defini

40、tion of stationary and displaceable machine, see 3.10 and 3.11. NOTE 2 Dimension saws are used for ripping, cross cutting, dimensioning and grooving. The requirements of this document apply also to machines designed for grooving with a width not exceeding 20 mm in one pass by using a milling tool. T

41、his document is not applicable to dimension saws which are manufactured before the date of its publication as a European Standard. NOTE 3 Machines covered by this document are listed under 1.1 of Annex IV of the Machinery Directive. 2 Normative references The following documents, in whole or in part
