33、epared 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 extent to which hazards, hazardo
34、us 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 precedence over the provisions of other standards, for machines th
35、at have been designed and built in accordance with the requirements of the provisions of this type C standard. The requirements of this document concern manufacturers, suppliers and importers of single blade circular log saw machines with integrated feed and manual loading and/or unloading. It is al
36、so 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 847-1:2005+A1:2007. BS EN 1870-7:2012EN 1870-7:2012 (E) 7 1 Scope This European Standard deals with all significant hazards, hazardous situ
37、ations and events as listed in Clause 4 which are relevant to single blade circular log sawing machines with saw blade diameter 600 mm and with integrated feed table with manual loading and/or unloading, (hereinafter referred to as machines), designed to cut solid wood when they are used as intended
38、 and under the conditions foreseen by the manufacturer including reasonably foreseeable misuse.
