Food processing machinery - Dishwashing machines with conveyor - Safety and hygiene requirements
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 manu

1.1 La présente Norme européenne s’applique aux lave-vaisselle multizone de type convoyeur à doigts (avec tapis) ou à avancement de casiers. Les zones de chargement et de déchargement des convoyeurs à doigts font partie de la machine.
Les machines couvertes par la présente Norme européenne sont conçues pour laver, rincer et éventuellement sécher la vaisselle et la batterie utilisées dans des locaux de restauration collective, tels que les restaurants, les hôtels, etc.
La présente Norme européenne s’applique aux lave-vaisselle à convoyeur dont la vitesse linéaire est inférieure ou égale à 5 m/min pour la vaisselle et la batterie.
NOTE Normalement, la puissance totale de ces machines est inférieure à 200 kW.
La présente Norme européenne traite de tous les phénomènes dangereux, situations et événements dangereux correspondant aux lave-vaisselle à convoyeur, lorsqu'ils sont utilisés normalement et dans les conditions prévues par le fabricant (voir Article 4).
La présente Norme européenne traite des phénomènes dangereux qui peuvent se produire au cours de l’installation, du fonctionnement, de la maintenance et de la mise hors service de la machine.
Lors de l'élaboration de la présente Norme européenne, les suppositions suivantes ont été élaborées :
- seules des personnes adultes utilisent les machines ;
- les machines sont utilisées dans une zone suffisamment éclairée.
La présente Norme européenne, qui se réfère à l'EN 60204-1 pour la sécurité électrique avec les critères applicables à différentes conceptions et variantes, est principalement destinée aux machines fabriquées en petites séries.
1.2 La présente Norme européenne ne s’applique pas :
- aux convoyeurs de chargement et de déchargement mécaniques séparés ;
- aux dispositifs de dosage de produits chimiques non intégrés à la machine ;
- aux générateurs de vapeur ;
- au matériel de chauffage au gaz.
1.3 Le bruit n’est pas considéré comme un risque significatif pour ces machines. Cela ne signifie pas
Stroji za predelavo hrane - Stroji za pomivanje posode s transportnim trakom - Varnostne in higienske zahteve (vključno z dopolnilom A1)
Ta evropski standard velja za večconske stroje za pomivanje posode z gnanim mimobežnim trakom (tekoča vrsta) ali transportnim trakom. V primeru tekoče vrste so območja nalaganja in razkladanja del tega stroja. Stroji, zajeti s tem evropskim standardom, so namenjeni za pomivanje, spiranje in možno sušenje posode in kuhinjskih pripomočkov, uporabljenih v prostorih za hrano in gostinstvo kot so na primer restavracije, hoteli, itd. Ta evropski standard velja za stroje za pomivanje posode s transportnim trakom linearne hitrosti, manjše ali enake 5 m/min za posodo in kuhinjske pripomočke.

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.
