National foreword This standard includes safety requirements. This document (EN 12043:2014) has been prepared by Technical Committee CEN/TC 153 “Machinery
5、 intended for use with foodstuffs and feed” (Secretariat: DIN, Germany). The responsible German body involved in its preparation was the DIN-Normenausschuss Maschinenbau (DIN Standards Committee Mechanical Engineering), Working Committee NA 060-18-01 AA Bckereimaschinen of Section Nahrungsmittel- un
6、d Verpackungsmaschinen. Representatives of manufacturers and users of bakery equipment, and of the employers liability insurance associations contributed to this standard. This standard contains specifications meeting the essential requirements set out in Annex I of the “Machinery Directive”, Direct
7、ive 2006/42/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,
8、it is deemed 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 corre

Where the International Standards referred to are not also DIN ISO Standards with the same number, there are no national standards available.

This European Standard shall be given the status of a national standard,
24、 either by publication of an identical text or by endorsement, at the latest by May 2015 and conflicting national standards shall be withdrawn at the latest by May 2015. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and/or C
25、ENELEC shall not be held responsible for identifying any or all such patent rights. This document supersedes EN 12043:2000+A1:2010. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of
26、EU Directive 2006/42/EC. For relationship with EU Directive 2006/42/EC, see informative Annex ZA, which is an integral part of this document. Significant changes: The significant changes with respect to the previous edition EN 12043:2000+A1:2010 are listed below: protective measures for the loading
27、were modified; requirements for emergency stop were added; requirements for nip guards were stated more precisely; thermal hazards, lamps, and hazards generated by UV radiation were added; the table of verification of safety and hygiene requirements was completely revised. According to the CEN-CENEL

DIN EN 12043:2015-02EN 12043:2014 (E) 5 Introduction This European Standard is a type C standard as stated in EN
30、ISO 12100. The machinery concerned and the extent to which hazards, hazardous situations and events are covered 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 typ
31、e C standard take precedence over the provisions of the other standards, for machines that have been designed and built according to the provisions of this type C standard. DIN EN 12043:2015-02EN 12043:2014 (E) 6 1 Scope 1.1 This European Standard specifies safety and hygiene requirements for the de
32、sign and manufacture of intermediate provers with powered moving pocket carriers as described in Clause 3 and used in the food industry, pastry-making, bakeries, etc. for giving a resting time to dough between different phases of the process. This European Standard deals with all significant hazards
33、, hazardous situations and events relevant to the installation, adjustment, operation, cleaning, maintenance, dismantling, disabling and scrapping of intermediate provers with moving pocket carriers when they are used as intended and under conditions of misuse which are reasonably foreseeable by the
34、 manufacturer (see Clause 4). Noise is not considered to be a significant hazard by intermediate provers. This does not mean that the manufacturer of the machine is absolved from reducing noise and making a noise declaration. Therefore a noise test code is proposed in Annex A. 1.2 The following mach
35、ines are excluded: independent automatic loading system not integrated with the machine; experimental and testing machines under development by the manufacturer; retarder and final proofer. 1.3 This European Standard is not applicable to intermediate provers with moving pocket carriers which are man
36、ufactured 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 are indispensable for its application.

There are openings in the frame where dough portions are introduced into the machine and where they are taken out. The position of loading and unloading depends on the frame shape and the path of movement of the poc
