EN 1807:1999+A1:2009 (E) 4 Introduction This European Standard has been prepared to be a harmonised standard to provide one means of conforming to the Essential Health and Safety Requirements of the Machinery Directive and associated EFTA Regulations.
This European Standard is a type "C" standard as defined in !EN ISO 12100-1:2003". The extent to which hazards are covered is indicated in the scope of this European Standard. The requirements of this standard concern designers, manufacturers, suppliers and importers of band sawing machines, re-sawing machines and log sawing machines. This European Standard also includes information to be provided by the manufacturer to the user. 1 Scope !This document specifies all significant hazards, hazardous situations and events as listed in Clause 4 which are relevant to stationary and displaceable band sawing machines with either manual or automatic loading and/or unloading, hereinafter referred to as “machines” designed to cut solid wood, chipboard, fibreboard, plywood and also these materials where they are covered with plastic laminate or edgings." !deleted text" !deleted text" This European Standard does not cover the hazards related to Electromagnetic Compatibility (EMC) as required by the EMC Directive 89/336/EEC of 03-05-89. This European Standard does not apply to:  !hand held motor-operated electric tools or any adaptation permitting their use in a different mode, i.e. bench mounting;" !NOTE 1 Hand-held motor operated electric tools are covered by the requirements of
EN 60745-1:2006 together with EN 60745-2-20:2003."  !transportable machines set up on a bench or a table similar to a bench, which are intended to carry out work in a stationary position, capable of being lifted by one person by hand." !NOTE 2 Transportable electrically driven machines are covered by the requirements of EN 61029-1:2000 together with EN 61029-2-5:2002." This European Standard does not cover the hazards arising from machining processes (e.g. milling and sawing) of related to associated machines e.g. canters and circular saws. This European Standard is primarily directed at machines which are manufactured after the date of issue of this standard. SIST EN 1807:2000+A1:2009

The safety related control systems of this machine are those for:  starting the drive motor for the driven band wheel (see 5.1.3);  starting the integrated feed (see 5.1.3 and 5.1.3.1);  normal stopping (see 5.1.4.1 and 5.1.4.2);  emergency stopping (if required) (see 5.1.5);  stopping powered feed rollers (see 5.1.2.1 and 5.1.5);  interlocking (see 5.2.7.1.1, 5.2.7.2.1, 5.2.7.3.1, 5.2.7.3.2, 5.2.7.4 and 5.2.8);  interlocking with guard locking (see 5.2.7.1.1, 5.2.7.2.1, 5.2.7.3.1 and 5.2.8);  mode selection (if required) (see 5.1.6);  opening/closing the adjustable saw blade guard during movement of the reciprocating carriage, moving head rig, conveyor feed or travelling table (see 5.2.7.3.2.1);  trip devices (where fitted) (see 5.2.7.2.5);  activation of the compensation device (see 5.2.3.1);  initiation of the braking system (see 5.2.4);  brake release (see 5.1.6);  pressure sensitive devices (where fitted) (see 5.2.7.2.4); SIST EN 1807:2000+A1:2009



EN 1807:1999+A1:2009 (E) 23  opto-electronic devices (where fitted) (see 5.2.7.2.4). These control systems shall be designed and constructed using “well tried components and principles”. For the purpose of this standard “well tried components and principles” means: a) electrical components if they comply with relevant standards including:  !EN 60947-5-1:2004" (section 3) for control switches with positive opening operation used as mechanically actuated position detectors for interlocking of guards and for relays used in auxiliary circuits;  !EN 60947-4-1:2001" for electromechanical contactors and motor-starters used in mains circuits;  !HD 22.1 S4:2002" for rubber insulated cables;  !HD 21.1 S4:2002" for polyvinyl chloride cables if these cables are additionally protected against mechanical damage by positioning (e.g. inside frames). b) electrical principles if the controls comply with the first four measures listed in 9.4.2.1 of !EN 60204-1:2006".
The circuits shall be 'hardwired'.
