This European Standard specifies safety and hygiene requirements for the design and manufacture of dough sheeters, as described in Clause 3, used in the food industry and craft activities (bread-making, pastry-making, sweet industries, bakeries, confectioners, delicatessens, catering facilities, etc.) for reducing the thickness of a solid mass of dough or pastry by rolling it out. This European Standard deals with all significant hazards, hazardous situations and events relevant to the transport, installation, adjustment, operation, cleaning, maintenance, dismantling, disassembling and scrapping of dough mixers, when they are used as intended and under the conditions of misuse which are reasonably foreseeable by the manufacturer (see Clause 4). This European Standard deals with all significant hazards, hazardous situations and events relevant to dough sheeters, when they are used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer (see Clause 5). Noise is not considered to be a significant hazard. This does not mean that the manufacturer is absolved from reducing noise and making a noise declaration. Therefore a noise test code is given in Annex B. The following machines are excluded: – experimental and testing machines under development by the manufacturer; – dough sheeters where the dough is fed to the rollers by gravity (e.g. pizzabase dough sheeters); – domestic appliances ). This European Standard is not applicable to dough sheeters which are manufactured before the date of its publication as EN.
