DIN EN 12268:2011-02

This standard defines relevant requirements set out in Annex I of the EC Machinery Directive 2006/42/EC, relating to machines which were placed on the European Economic Area (EEA) market for the first time, with the intent of simplifying the means of proving conformity with such requirements. Once this standard is designated a harmonized standard in the Official Journal of the European Communities, a manufacturer applying this standard may assume compliance with the requirements of the Machinery Directive (the so-called presumption of conformity). This European Standard specifies requirements for the design and manufacturing of band saw machines. The machines covered by this European Standard are used to cut bone and meat. The band saw machines covered by this European Standard do not include band saw machines for processing wood and similar materials and the requirements described in EN 1807 do not apply. Band saw machines for domestic use are not included in this European Standard. This European Standard only applies to machines which are manufactured after the date of issue of this European Standard. This standard covers the following types of machines: band saw machines designed as table-top machines with and without base; band saw machines designed as floor-type machines; band saw machines integrated in a cutting line. Band saw machines which are placed on the floor can be wheel-mounted. Type A band saw machine with a feed table and a fixed product pusher cutting height SH < 250 mm location: table or base. Distance A from the floor to the top surface of the feed table is usually between 800 mm and 1 050 mm. Type B band saw machine with a feed table, a protective rail and a cutting height 250 mm ≤ SH < 420 mm. Distance A from the floor to the top surface of the feed table is between 800 mm and 1 050 mm. Location: floor. Type C band saw machine with a sliding feed table, a protective rail and a cutting height 250 mm < SH < 420 mm. Distance A from the floor to the top surface of the sliding feed table is between 800 mm and 1 050 mm. Location: floor. Type D band saw machine with feed and removal unit (for example, roller conveyor, conveyor belt); integrated in a cutting plant, cutting height SH < 550 mm. Distance A from the floor to the feed surface is usually between 800 mm and 1 050 mm. Location: floor. Band saw machines consist of a machine casing, a fixed feed table or a sliding feed table, a roller conveyor or conveyor belt, a product pusher, a height-adjustable protective rail, a bottom and a top wheel, a saw blade, an upper and lower blade guide, a blade tensioning device, a drive and electrical components, depending on machine type. The requirements for automatic loading/unloading systems, conveyors, etcetera, do not fall within the scope of this European Standard. This European Standard deals with all significant hazards, hazardous situations and events relevant to band saw machines when they are used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer (see clause 4). This European Standard deals with the hazards which can arise during commissioning, operation, cleaning, use, maintenance and decommissioning of the machines. On floor-type band saw machines, the product to be cut is placed by hand onto the fixed feed table or sliding feed table and pushed against the cutting zone of the saw blade by means of the product pusher or the rear table wall on the sliding feed table or by means of the roller conveyor or conveyor belt and sawed. This standard contains the German version of EN 12268:2003+A1:2010, which has been prepared by Technical Committee ISO/TC 153 "Machinery intended for use with foodstuffs and feed" of the European Committee for Standardization (CEN). The following modifications have been made with respect to DIN EN 12268:2003: a) The standard has been modified and adapted with respect to the new Machinery Directive 2006/42/EC; b) An informative Annex ZB on the relationship between this European Standard and the essential requirements of Machinery Directive 2006/42/EC has been added. The national interests during the preparation of the standard were represented by Committee NA 060-18-02 AA "Fleischverarbeitungsmaschinen" ("Meat processing machinery") of Technical Section "Food Processing Machinery" of the Mechanical Engineering Standards Committee (NAM) at DIN. Representatives of the interested parties were involved in the preparation of this standard.
