25、t has been prepared to be a harmonised standard to provide one means of conforming with the Essential Safety Requirements of the Machinery Directive and associated EFTA Regulations and is a type C standard as defined in !EN ISO 12100:2010“. The machinery concerned and the extent to which hazards, ha

26、zardous situations and events 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 C type standard take precedence over the provisions of other standards, for machines t

27、hat 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 combined woodworking machines. They are also useful for designers. This document also includes provisions and

28、example of information to be provided by the manufacturer to the user. Common requirements for tooling are given in !EN 847-1:2005+A1:2007“.

31、 foreseeable misuse“. NOTE 1 For the definitions of stationary and displaceable machine see !3.2.12 and 3.2.13“. NOTE 2 The specific requirements on demountable power feed unit will be considered during next revision of this document. This document does not apply to: combined machines which consist

32、only of a surface planing unit and a thickness planing unit; NOTE 3 Combined machines consisting of only of a surface planing unit and a thickness planing unit are dealt with in !EN 861:2007+A2:2012“. combined machines with a band saw unit; transportable motor-operated electric combined tools, or an
