This standard contains specifications meeting the essential requirements set out in Annex I of the “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 fac

7、ilitate 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, a manufacturer applying this standard may assume compliance with the requirements of the Machinery

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

36、n 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 type C standa

37、rd. The extent to which significant hazards are covered is indicated in Clause 1. It is indicated in greater detail in Clause 4. Manufacturers are required to collect, retain and make available sufficient information, to enable centrifuges to be installed, commissioned, used, maintained and disposed

38、 of safely, i.e. that information is made available to users of centrifuges. Different applications and particular centrifuge designs exist. Annex A includes more details of both of these ranges. DIN EN 12547:2014-12 EN 12547:2014(E)7 1 Scope 1.1 This European Standard applies to centrifuges for the

39、 separation or change in concentration of mixtures of liquids and solids. It gives requirements to minimize the risks caused by the significant hazards arising during the operation of centrifuges as specified in 1.2. 1.2 This European Standard gives requirements for minimizing the risks caused by th

40、e following hazards: mechanical hazards common to all types of centrifuges, except those specified in 1.3; ergonomical hazards; thermal hazards; electrical hazards; noise. 1.3 Types of centrifuges and hazards excluded 1.3.1 Types of centrifuges excluded: centrifuges with a kinetic energy of rotation

41、 less than 200 J; centrifuges for household use; centrifuges for laboratory use according to EN 61010-2-020; centrifuges for forming, i.e. centrifugal hot metal casting machines. 1.3.2 Hazards excluded This European Standard does not deal explicitly with the hazards listed below. NOTE 1 In cases, wh

42、ere such hazards might occur and could become relevant for the construction of the centrifuge, use specific standards for this hazard or make a risk assessment. hazards caused by overpressure or negative pressure inside the centrifuge housing; hazards specific to processing radioactive products; haz

43、ards specific to microbiological processing - including viral and parasitic hazards; hazards from processing corrosive and/or erosive materials; hazards from processes involving flammable or explosive substances; hazards caused by leakage of hazardous substances; hazards caused by unsuitable hygieni

45、or example. Other substances may be hazardous because of their condition in the centrifuge, i.e. temperature, velocity and vapour pressure. hazards due to construction materials; Materials used in the construction of centrifuges should not be hazardous in the condition in which they are used. centri

46、fuges subject to application specific standards (e.g. EN 12505). NOTE 3 The design of centrifuges covered by EN 12547 varies to the extent that additional hazards may exist that are not covered by the requirements of this standard and is not excluded above. The manufacturer is responsible for provid

47、ing suitable measures to deal with these hazards as part of a general risk assessment for the machine. Such measures are outside the scope of this standard and the direct responsibility of the manufacturer. 1.3.3 This European Standard gives guidance on the selection of performance levels according

48、to EN ISO 13849-1:2008, but does not identify performance levels for specific applications. 1.4 This European Standard is not applicable to centrifuges 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 are indispensable for its application.
