5、es effect on 1 October 2010. National foreword This standard includes safety requirements. This standard has 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

6、the Normenausschuss Maschinenbau (Mechanical Engineering Standards Committee), Working Committee NA 060-18-07 AA Nudelherstellungs- und Getreideverarbeitungsmaschinen of Section Nahrungsmittelmaschinen. Stakeholders were involved in the development of the standard. This standard contains specificati

7、ons meeting the essential requirements set out in Annex I of the new “Machinery Directive”, Directive 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 requireme

8、nts of that directive. Once this standard is cited in the Official Journal of the European Union, 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 St

9、andards 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 the same number. Amendments This standard differs from DIN EN 14958:2007-06 as follows: a) the standard has been brought in line with the new Machinery Direc

10、tive 2006/42/EC; b) Annex ZB (informative) “Relationship between this European Standard and the Essential Requirements of EU Directive 2006/42/EC” has been added.

The machinery concerned and the extent to which hazards, hazardous situations and hazardous events are covered are indicated in the scope of this do

28、cument. 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 designed and built according to the provisions of this typ

29、e C standard. Complementary to the hygiene requirements common to all food processing machines, specific requirements for cleanability and sanitation of the machines in the scope are formulated.“ DIN EN 14958:2010-10 EN 14958:2006+A1:2009 (E) 5 1 Scope This European Standard deals with the significa

30、nt hazards, hazardous situations and events relevant to the following machinery for grinding and processing of flour and semolina, as defined in Clause 3: roller mills, plan sifters and rotary separators, air classifiers, rotating machines and impact machines. The machines in the scope are stationer

31、y (not intended to be moved when in operation), have a capacity of at least 100 kg/h, and are intended for use in installations for grain processing, such as flour mills, semolina mills, grain cleaning and flaking plants. This European Standard deals with the significant hazards during commissioning

32、, operation, cleaning and maintenance of the machines in the scope when they are used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer. This European Standard is not applicable to: machines intended for household use or laboratory use; stone mills; equi

33、pment for dampening and heating; auxiliary equipment for conveying, weighting and bagging (without changing the characteristics of the products). This European Standard is not dealing with the following: hazards related to decommissioning; the hazards of the installations into which the machines are

34、 incorporated other than those directly related to the machines in the scope (e.g. start of the installation, disconnection of energy supply, need from an emergency stop device); hazards due to the use of the machinery in a potentially explosive atmosphere (when producing this standard it has been a

35、ssumed that the machinery in the scope, if designed and used in accordance with this European Standard, is not creating itself a hazardous atmosphere wholly of partly surrounding it). NOTE If the machine is intended for use in a potentially explosive atmosphere, additional safety measures can be nec

36、essary1). This European Standard is not applicable to machines for grinding and processing of flour and semolina which are manufactured before the date of its publication as EN. 2 Normative references The following referenced documents are indispensable for the application of this document.
