1 Scope 1.1 This European Standard applies to multizones dishwashing-machines with passing 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 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 Normally 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 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, operation, 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 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 from reducing noise and making a noise declaration. Therefore a noise test code is included in Annex 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. 2 Normative references The following referenced documents are indispensable for the application of this document.

Figures 1a and 1c) 3.1.3 dishes pans, containers, plates, cups etc., used in the professional catering and restaurants 3.1.4 inspection door door giving access to the processing zones for cleaning and maintenance 3.1.5 access for technical area door or panel giving access to technical areas for repair and/or maintenance 3.1.6 multizone machine machine where the different functions (e.g. washing, rinsing, drying) are located in different areas of the machine 3.2 Description A dishwashing machine with conveyor is generally composed of:  a frame;  doors giving access to the different zones;  a motorised belt or rack conveyor;  a water heating device;  a water circulation device. The main different zones can be:  a loading area;  a washing compartment;  a rinsing compartment;  a drying compartment;  a vapour exhaust device;  one or several electrical and/or electronic compartments;  a control panel;  dosing device, if any; SIST EN 14957:2007+A1:2010

This specific risk assessment shall be part of the general risk assessment of the machine. !When interlocking devices are referred to in Clause 5, they should preferably be position detectors with positive opening contact complying with the recommendations of standard EN 1088:1995, 4.2.1 (interlocking without guard locking) and Clauses 5 and 6. However, due to practical reasons (e.g. cleaning), magnetic switches (reed switches) in accordance with EN 1088:1995 are allowed. The parts of the control system related to the interlocking shall meet at least category 1 of 6.2.2 of EN 954-1:1996 or present at least a performance level c defined in accordance with EN ISO 13849-1. Fixed and movable guards shall comply with EN 953." Except where otherwise provided, interlocking shall be control interlocking as defined in EN 1088:1995, 4.1.1. Manually operated control devices of the dishwashing machines shall be located out of the hazardous zones. SIST EN 14957:2007+A1:2010
