BS EN 14957:2006+A1:2010EN 14957:2006+A1:2010 (E) 5 Introduction This European Standard is a type C standard as stated in EN ISO 121

25、00. 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 B standards, the provisions of this type C standard

26、 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. BS EN 14957:2006+A1:2010EN 14957:2006+A1:2010 (E) 6 1 Scope 1.1 This European Standard applies to multizones dishwashing-machines with pass

27、ing through motorized belt (flight type) or rack conveyor. In case of flight type, the loading and unloading areas are part of the machine. The machines covered by this European Standard are intended for washing, rinsing and optionally drying the dishes and the kitchen utensils, used in food and cat

28、ering premises such as restaurants, hotels etc. This European Standard applies to dishwashing machines with conveyor with a linear speed less than or equal to 5 m/min for the dishes and kitchen utensils. NOTE Normally the total power of these machines is less than 200 kW. This European Standard deal

29、s with all significant hazards, hazardous situations and events relevant to dishwashing machines with conveyor, when they are used as intended and under the conditions foreseen by the manufacturer (see Clause 4). This European Standard deals with the hazards which can arise during commissioning, ope

30、ration, maintenance and decommissioning of the machine. When drawing up this European Standard the following assumptions were made: only trained adult persons operate the machines; the machines are used in adequately illuminated areas. This European Standard, referring for electrical safety to EN 60

31、204-1 with criteria that can be applied to different designs and variants, is mainly intended for machines manufactured in small series. 1.2 This European Standard does not apply to: separate mechanical loading and unloading conveyors; chemical dosing devices which are not incorporated into the mach

32、ine; steam generators; gas heating equipment. 1.3 Noise is not considered to be a significant hazard for these machines. This does not mean that the manufacturer of these machines is absolved from reducing noise and making a noise declaration. Therefore a noise test code is included in Annex A. 1.4

33、This European Standard is not applicable to dishwashing-machines with conveyor which are manufactured before the date of publication of this European Standard by CEN. 2 Normative references The following referenced documents are indispensable for the application of this document.
