Start of validity This standard takes effect on 1 October 2010. National foreword This standard includes safety requirements. This standard has
5、 been prepared by Technical Committee CEN/TC 153 “Machinery intended for use with foodstuffs and feed” (Secretariat: DIN, Germany). The responsible German body involved in its preparation was the Normenausschuss Maschinenbau (Mechanical Engineering Standards Committee), Working Committee NA 060-18-0
6、1 AA Bckereimaschinen of Section Nahrungsmittelmaschinen. Stakeholders were involved in the development of the standard. This standard contains specifications meeting the essential requirements set out in Annex I of the new “Machinery Directive”, Directive 2006/42/EC, and which apply to machines tha
7、t 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 deemed a “harmonized” standard and thus,
8、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 DIN EN or DIN EN ISO Standards with th
9、e same number. Amendments This standard differs from DIN EN 1673:2001-02 as follows: a) the standard has been brought in line with the new Machinery Directive 2006/42/EC; b) Annex ZB (informative) “Relationship between this European Standard and the Essential Requirements of EU Directive 2006/42/EC”

This European Standard shall be given the status of a national standard, either by p
23、ublication of an identical text or by endorsement, at the latest by June 2010, and conflicting national standards shall be withdrawn at the latest June 2010. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and/or CENELEC shall
24、 not be held responsible for identifying any or all such patent rights. This document includes Amendment 1 approved by CEN on 24 October 2009. This document supersedes EN 1673:2000. The start and finish of text introduced or altered by amendment is indicated in the text by tags !“. This European Sta
25、ndard has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of EU Directive(s). !For relationship with EU Directive(s), see informative Annexes ZA and ZB, which are integral parts of this document.“ Acco
26、rding to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latv

Introduction !This European Standard is a type C standard as stated in EN ISO 12100. The machinery concerned and the extend to which hazards, hazar
28、dous 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 type C standard take precedence over the provisions of the other standards,
29、for machines that have been designed and built according to the provisions of this type C standard.“ 1 Scope This standard specifies safety and hygiene requirements for the design and manufacture of rotary rack ovens with one or more rotary racks. DIN EN 1673:2010-10 EN 1673:2000+A1:2009 (E) 4 These
30、 ovens are used in the food industry and shops (bakeries, pastry-making, etc.) for the batch baking of foodstuffs containing flour, water and other additives. This standard applies to ovens used only for food products except for those containing volatile flammable ingredients. The control of the hum
31、idity of the air in the baking chamber is by the production and introduction of steam around normal atmospheric pressure. The following machines are excluded: experimental and testing machines under development by the manufacturer; domestic appliances. !This standard covers the technical safety requ
32、irements for the transport, installation, operation, cleaning and maintenance of these machines (see 5.2 and 5.3 of EN 12100-1:2003).“ This document deals with all significant hazards, hazardous situations and events relevant to rotary rack ovens, when they are used as intended and under conditions
33、of misuse which are reasonably foreseeable by the manufacturer (see Clause 4). 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 hazards fr
34、om the use of gaseous fuel by gas appliances are not covered by this standard. !This standard is not applicable to rotary rack ovens which are manufactured before the date of its publication as EN.“ 2 !Normative references The following referenced documents are indispensable for the application of t

47、ous situations and events, as far as they are dealt with in this Standard, identified by risk assessment as significant for this type of machinery, and which require action to eliminate or reduce the risk.“ 4.2 Mechanical hazards The significant mechanical hazards are: shearing hazard; trapping haza
48、rd; impact hazard; loss of stability. The example in figure 2 shows the danger zones: Zone 1: rotation of the rack inside the oven hazards of shearing, trapping, impact; Zone 2: drive mechanism hazards of shearing, trapping; Zone 3: space between the rack and the door frame hazards of shearing, trap
49、ping, impact; All zones: sharp corners and edges on touchable parts hazards of cutting.
