1.1 This European Standard applies to multizones dishwashing-machines with passing through motorized belt(flight type)or rack conveyor.ln case of flight type,the loading and unloading areas are part of the machine.
The machines xovered by this European Standard are intended for washing,rinsing and optionally drying the dishes and the kitchen utensils,used in food and catering 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 ormally the total power of these machines is less than 200 Kw.
This European Standard deals with all significant hazards,hazardous situations and events relevant to dishwashing machines with conveou ,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,operation,maintenance and decommissioning of the machine.
When draawing 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 60204-1 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 machine;
- 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 fromreducing noise and making a noise declaration.Therefore a noise test code is included in Annes A.
1.4 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.
