Safety of woodworking machines - Circular sawing machines - Part 15: Multi-blade cross-cut sawing machines with integrated feed of the workpiece and manual loading and/or unloading
This European Standard specifies all requirements and/or measures to reduce the hazards and limit the risks on multi-blade cross-cut sawing machines (with minimum two saw unit) 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, when they are used as intended and under the conditions foreseen by the manufacturer including reasonably foreseeable misuse. This document deals with all significant hazards, hazardous situations and events which are 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 document does not cover machines designed for climb cutting (see 3.2.10). The requirements of this document apply to all machines whatever their method of control e.g. electromechanical and/or electronic and/or pneumatic. This document is not applicable to multi-blade cross-cut sawing machines with integrated feed of the workpiece and manual loading and/or unloading which are manufactured before the date of its publication as EN.

This document is a type C standard as defined in EN ISO 12100:2010. 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 according to the provisions of this type C standard. The requirements of this document are directed to manufacturers and their authorised representatives of multi-blade cross-cut sawing machines with integral feed of the work-piece and manual loading and/or unloading. It is also useful for designers and importers. 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. SIST EN 1870-15:2012
