EN 1218-2:2004+A1:2009 (E) 5 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 standard as stated in !EN ISO 12100-1:2003". The machinery concerned and the extent to which hazards, hazardous 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 that have been designed and built in accordance with the provisions of this type C standard. The requirements of this document are directed to manufacturers and their authorised representatives of double end tenoning and/or profiling machines fed by chain or chains. 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".

1 Scope !This document deals with all the significant hazards, hazardous situations and events as listed in Clause 4 which are relevant to double end tenoning and/or profiling machines fed by chain or chains, hereinafter referred to as the machine, designed to cut solid wood, chipboard, fibreboard or plywood and also these materials where they are covered with plastic laminate or edgings. The workpiece is fed passed the tools by an integrated feed." !deleted text" This document does not apply to: a) double end tenoning and/or profiling machines fed by chain or chains with a complete enclosure as defined in 3.3.11; b) transportable machines. This document does not deal with any hazards relating to: c) mechanical loading of the workpiece to a single machine; or d) single machine being used in combination with any other machine (as part of a line); or e) use of tools working between the machine halves (see 3.1); or f) use of laser. For Computer Numerically Controlled (CNC) machines this document does not cover hazards related to Electro-Magnetic Compatibility (EMC). NOTE 1 The requirements of this document apply to all machines whatever their method of control e.g. electromechanical and/or electronic. This document is primarily directed to machines which are manufactured after the date of publication by CEN. NOTE 2 Single end tenoning machines with sliding table are dealt with in EN 1218-1:1999. Single end tenoning machines where the tenon is produced only by means of saw blades are dealt with in EN 1218-3. Single end profiling machines fed by chain or chains are dealt with in EN 1218-5. 2 Normative references The following referenced documents are indispensable for the application of this document.
