22、s - Safety”, the secretariat of which is held by UNI. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by May 2014, and conflicting national standards shall be withdrawn at the latest by May 2014. Att
23、ention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and/or CENELEC shall not be held responsible for identifying any or all such patent rights. This document together with EN 1870-18 supersedes EN 1870-1:2007+A1:2009. The major techn
24、ical changes from the previous edition are the following: a) the exclusion of saw blade guard mounted on wall, ceiling or floor; b) introduction of PL; c) inclusion of a stability test for displaceable machines; d) more precise requirements for braking function; e) more precise requirement on chips
25、and dust extraction connections; f) extension of usable safety appliances; g) more precise requirements to prevent crushing and shearing hazards. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential re
26、quirements of the Machinery Directive. For relationship with EU Directive(s), see informative Annex ZA, which is an integral part of this document.

The European Standards produced by CEN/TC 142 are particular to woodworking machines and complement the relevant A and B Standards on the subject of general safety (see Introductio
33、n of EN ISO 12100:2010 for a description of A, B and C standards). According to the CEN-CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, E

35、 1870-19:2013 (E) 7 Introduction This document has been prepared 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 document is a type “C“ standard as defined in EN ISO 12100:2010. The m
36、achinery concerned and the extent to which hazards, hazardous situations and events are 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 type C standard take precede
37、nce over the provisions of other standards, 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 authorized representatives of circular saw benches (with and without sliding table
38、) and building site 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 tooling are given in EN 847-1:2013. BS EN 1870-19:2013EN 1870-19:2013 (E) 8 1 Scope This European S
39、tandard deals with all significant hazards, hazardous situations and events as listed in Clause 4 which are relevant to stationary and displaceable circular saw benches (with or without sliding table and/or demountable power feed unit) and building site saws, hereinafter referred to as “machines”, d
40、esigned 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. Machines whi
41、ch are designed to cut wood-based material may also be used for cutting hardened plastic materials with similar physical characteristics as wood. NOTE 1 For the definition of stationary and displaceable machine see 3.2.9 and 3.2.10. NOTE 2 Circular saw benches are used for ripping, cross cutting, di
42、mensioning and grooving. Building site saws are used for ripping, cross cutting and dimensioning. 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. This document does not apply to: a) machines set up o
43、n a bench or a table similar to a bench, which are intended to carry out work in a stationary position, capable of being lifted by one person by hand. The bench can also be an integrated part of the machine if it consists of hinged legs which can be extended down; b) hand held woodworking machines i
44、ncluding any adaptation permitting their use in a different mode, i.e. bench mounting. NOTE 3 Transportable motor-operated electric tools are covered by the requirements of EN 61029-1:2009 together with EN 61029-2-1:2012; a hand-held motor-operated electric tool and a saw bench to form an integrated
45、 whole are covered by EN 60745-1:2009 together with EN 60745-2-5: 2010. For the purpose of this document, building site saws having a tiltable spindle are considered to be circular saw benches. This document is not applicable to circular saw benches (with and without sliding table) and building site
46、 saws which are manufactured before the date of its publication as EN. NOTE 4 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, are normatively referenced in this document and are indisp
47、ensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.
