28、Organisations contributing to the preparation of this European Standard include European Committee of Woodworking Machinery Manufacturers Association “EUMABOIS“. The European Standards produced by CEN/TC 142 are particular to woodworking machines and complement the relevant A and B Standards on the
29、subject of general safety (see introduction of EN ISO 12100:2010 for a description of A, B and C standards). According to the CEN/CENELEC Internal Regulations, the national standards organisations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, C

BS EN 1870-12:2013EN 1870-12:2013 (E) 6 Introduction 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“ stan
32、dard 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. When provisions of this type C standard are different from those which are stated in type A or B standards, the prov
33、isions of this C type 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. The requirements of this document are directed to manufacturers and their authorised representatives of pendulum
34、cross-cut sawing machines. It is also useful for designers. This document also includes information which can be provided by the manufacturer to the user. Common requirements for tooling are given in EN 847-1:2005+A1:2007. BS EN 1870-12:2013EN 1870-12:2013 (E) 7 1 Scope This European Standard deals
35、with all significant hazards, hazardous situations and events as listed in Clause 4 which are relevant to pendulum cross-cut sawing, herein after referred to as machines, designed to cut solid wood, chipboard, fibreboard, plywood and also these materials when covered with plastic edging and/or plast
36、ic/light alloy laminates when they are used as intended and under the conditions foreseen by the manufacturer including reasonably foreseeable misuse. This European Standard does not apply to: a) machines for cross cutting logs; b) machines where the saw unit can be rotated about a horizontal axis.
37、NOTE 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 primarily directed at machines which are manufactured after the date of its publication as EN. 2 Normative references The followi
38、ng documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies.
