BS EN 1870-3:2014EN 1870-3:2014 (E) 6 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 European Standard is a type “C” standard as def

33、ined in EN ISO 12100:2010. The extent to which hazards are covered is 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 precedence over the provisions of oth

34、er 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 down cutting cross-cut saws and dual purpose down cutting cross -cut saws/circular

35、 saw benches. They are also useful for designers. This document also includes information to be provided by the manufacturer to the user. Common requirements for tooling are given in EN 847-1:2013. Electrically driven machines excluded by the scope of this document are covered by the requirements of

36、 EN 61029-1:2000, EN 61029-2-9:2009 and EN 61029-2-11:2009. BS EN 1870-3:2014EN 1870-3:2014 (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 down cutting cross-cut saws and dual purpose down cutting c

37、ross-cut saws/circular saw benches, herein after referred to as “machines”, designed to cut solid wood, chipboard, fibreboard, plywood and also these materials where they are covered with plastic edging and/or plastic/light alloy laminates when they are used as intended and under the conditions fore

38、seen by the manufacturer including reasonably foreseeable misuse. NOTE 1 For the definition of down cutting cross-cut saws and dual purpose down cutting cross -cut saws/circular saw benches, see 3.2.2, 3.2.3 and 3.2.4, and for the definition of displaceable machine, see 3.2.8.
