Electric dishwashers for commercial use - Test methods for measuring the performance
This European Standard applies for manually loaded undercounter one-tank and one-tank hood type electrically heated dishwashing machines for washing plates, dishes, glassware, cutlery and similar articles. These machines are used in commercial kitchens, such as restaurants, canteens, hospitals and in businesses such as bakeries, butcher shops, etc. This European Standard does not apply to commercial dishwashers with transport systems (flight-type and rack conveyor dishwashers) and utensil washers. This European Standard does not apply to undercounter water-change dishwashers. This European Standard does not apply to appliances designed exclusively for industrial purposes. The object is to state and define the principal performance characteristics of electric dishwashers for commercial use and to describe the standard methods of measuring these characteristics. The characteristics are measured by washing plates. This European Standard does not address safety requirements.
Elektrische Geschirrspüler für den gewerblichen Gebrauch - Messverfahren für Gebrauchseigenschaften
Diese Europäische Norm gilt für handbeladene Eintank-Untertisch-Spülmaschinen und Eintank-Hauben-Spülmaschinen zum Spülen von Tellern, Geschirr, Glasgeschirr, Besteck und ähnlichen Gegenständen. Diese Maschinen werden in gewerblichen Küchen, wie z. B. in Restaurants, Kantinen, Krankenhäusern, und in Geschäften, wie z. B. Bäckereien, Fleischereien usw., eingesetzt. Diese Europäische Norm gilt nicht für gewerbliche Spülmaschinen mit Transporteinrichtungen (Band-transport- und Korbtransport-Spülmaschinen) und Utensilien-Spülmaschinen. Diese Europäische Norm gilt nicht für wasserwechselnde Untertisch-Spülmaschinen. Diese Europäische Norm gilt nicht für Geräte, die ausschließlich für industrielle Zwecke ausgelegt sind. Das Ziel ist, die grundsätzlichen Gebrauchseigenschaften von elektrischen Spülmaschinen für den gewerb-lichen Gebrauch und die Normverfahren für die Messung dieser Leistungskenngrößen anzugeben und fest-zulegen. Die Leistungskenngrößen werden durch das Spülen von Tellern gemessen. Diese Europäische Norm behandelt keine Anforderungen hinsichtlich der Sicherheit.
