Safety of woodworking machines - Circular sawing machines - Part 15: Multiblade cross-cut sawing machines with integrated feed of the workpiece and manual loading and/or unloading
This European Standard specifies the requirements and/or measures to reduce the hazards and limit the risks on multi-blade cross-cut sawing machines with integrated feed of the work-piece and manual loading and/or unloading fitted with a saw blade drive motor for each saw unit, hereinafter referred to as "machines", designed to cut solid wood, chipboard, fibreboard, plywood and also these materials where they are covered with plastic edging and/or plastic/light alloy laminates.
This European Standard covers the hazards relevant to these machines as stated in Clause 4. It does not deal with any hazards relating to the mechanical loading and/or unloading of the work-piece or which result from the combination of the machine with any other.
This European Standard does not cover machines designed for climb cutting (see 3.10).
For Computer Numerically Controlled (CNC) machines this European Standard does not cover hazards related to electromagnetic compatibility (EMC).
The requirements of this European Standard apply to all machines whatever their method of control e.g. electromechanical and/or electronic.
This document is not applicable to multi-blade cross-cut sawing machines with integrated feed of the work-piece and manual loading and/or unloading which are manufactured before the date of publication of this document by CEN.
NOTE Machines covered by this European Standard are listed under A.1.3 of Annex IV of the Machinery Directive.

For guidance in connection with risk reduction by design, see Clause 4 of EN 12100-2:2003 and for safeguarding measures, see Clause 5 of EN ISO 12100-2:2003. 5.2 Controls 5.2.1 Safety and reliability of control systems For the purposes of this document a safety related part of control system is one from and including the initial manual control or position detector to the point of input to the final actuator or element e.g. motor. The safety related parts of control system of this machine are those for the following functions: starting and restarting of the saw-blade(s) rotation, the movements of the saw unit(s), the work-piece feed mechanism: Category 1 (see 5.2.3, 5.2.6); normal stopping: Category 1 (see 5.2.4); emergency stop: Category 1 or 3 (see 5.2.5); interlocking: Category 1 (see 5.3.7); interlocking between the feed chain motor with the position of the saw spindles: Category 1 (see 5.2.7); interlocking with guard locking: Category 1 (see 5.3.7); prevention unexpected start-up after failure of the power supply: Category 1 (see 5.3.8); hold-to run control : Category 1 (see 5.3.7.3); SIST EN 1870-15:2005
EN 1870-15:2004 (E) 14 control duplication (where fitted): Category 1 (see 5.2.7); initiation of the braking system: Category 1 (see 5.3.4). Any combination of safety-related parts of control systems of different categories which achieve at least the required level of fault resistance is acceptable in accordance with the requirements of 6.3 of EN 954-1:1996. For the purposes of this European Standard Category 1 of EN 954-1:1996 for parts and the function of these safety related control systems is achieved if e.g. for: a) electrical components if they comply with relevant standards including the following: i) EN 60947-5-1:1997 (section 3) for control switches with positive opening operation used as mechanically actuated position detectors for interlocking guards and for relays used i
