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

29、 this document. 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

30、 this type C standard. 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, main

31、tained and disposed 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. BS EN 12547:2014EN 12547:2014 (E) 7 1 Scope 1.1 This European Standard applies to cen

32、trifuges for the 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 ri

33、sks caused by the 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 en

34、ergy of rotation 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. NOT

35、E 1 In cases, where 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 radioacti

36、ve products; hazards 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 un

37、suitable hygienic design for applications involving food products; inherent chemical hazards of process materials and/or service media and their biological effects on exposed persons; BS EN 12547:2014EN 12547:2014 (E) 8 NOTE 2 Inherently hazardous substances include toxic, carcinogenic and flammable

38、 substances for 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

39、 used. centrifuges 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 responsib

40、le for providing 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 leve

41、ls according 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, a
