This document (EN 1674:2015) has been prepared by Technical Committee CEN/TC 153 “Machinery intended for u
5、se with foodstuffs and feed” (Secretariat: DIN, Germany). The responsible German body involved in its preparation was DIN-Normenausschuss Maschinenbau (DIN Standards Committee Mechanical Engineering), Working Committee NA 060-18-01 AA Bckereimaschinen of Section Nahrungsmittel- und Verpackungsmaschi
6、nen. Representatives of manufacturers and users of bakery equipment, and of the employers liability insurance associations contributed to this standard. This standard contains specifications giving detail to the essential requirements set out in Annex I of the “Machinery Directive”, Directive 2006/4
7、2/EC, and which apply to machines that are either first placed on the market or commissioned within the EEA. This standard serves to facilitate proof of compliance with the essential requirements of that directive. Once this standard is cited in the Official Journal of the European Union, it is deem
8、ed a “harmonized” standard and thus, a manufacturer applying this standard may assume compliance with the requirements of the Machinery Directive (“presumption of conformity”). The European Standards referred to in Clause 2 and in the Bibliography of the EN have been published as the corresponding D
9、IN EN or DIN EN ISO Standards with the same number. Where the International Standards referred to are not also DIN ISO Standards with the same number, there are no national standards available. Amendments This standard differs significantly from DIN EN 1674:2010-10 as follows: a) normative reference
10、s have been updated; b) the list of the significant hazards and danger zones for mechanical hazards has been specified in more detail; c) new subclauses have been added: 5.3.5 (Unexpected start-up) and 5.4 (Requirements concerning flour dust emission).

DIN EN 1674:2015-12 EN 1674:2015 (E) 5 Introduction This European Standard is a type-C-standard as stated in EN ISO 12100. The machinery concerned and the extent to which hazards, hazardous situations and events are c
30、overed are indicated in the scope of this European Standard. When provisions of this type-C-standard are different from those which are stated in type-A- or B-standards, the provisions of this type-C-standard take precedence over the provisions of the other standards, for machines that have been des
31、igned and built according to the provisions of this type-C-standard. DIN EN 1674:2015-12 EN 1674:2015 (E) 6 1 Scope 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 activit
32、ies (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
33、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
34、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
35、 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
36、 (e.g. pizzabase dough sheeters); domestic appliances1). This European Standard is not applicable to dough sheeters which are manufactured before the date of its publication as EN. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and ar

47、n a mobile or fixed base or placed on a table or a support. The operation is carried out by passing the dough back and forth between the rollers whose distance apart is reduced progressively either by manual adjustment or automatically. The frame supports the following components (see Figure 1): 1)
