Clothes washing machines for commercial use - Methods for measuring the performance
This Technical Specification specifies methods for measuring the performance of clothes washing machines for commercial use utilizing cold and/or hot water supply and without heating or with heating devices for electricity, steam or gas. It also deals with appliances for both washing and drying textiles (washer-dryers) with respect to their washing related functions. This Technical Specification covers top, front and side loaded non household washing machines with horizontal or vertical axis and with one or more wash compartments. NOTE 1 Non household tumble dryer performance is assessed to CLC/TS 50594. NOTE 2 Installation and energy calculations of non-household washing machines heated with gas is assessed in EN ZZZZZ. The object is to state and define the principal performance characteristics of non-household washing machines and to describe the test methods for measuring these characteristics. NOTE 3 This Technical Specification does not apply to continuous batch washing machines (e.g. tunnel washers) or washing machines only possible to operate with automatic loading and unloading. NOTE 4 This Technical Specification does not specify safety requirements for non-household washing machines. Safety requirements are specified in EN 50571 and the EN ISO 10472 series.
Waschmaschinen für den gewerblichen Gebrauch - Verfahren zur Messung der Gebrauchseigenschaften
Die vorliegende Technische Spezifikation spezifiziert Methoden für die Messung der Gebrauchseigen¬schaften von Waschmaschinen für den gewerblichen Gebrauch, welche Kalt- und/oder Warmwasser¬versorgung verwenden und keine Heizung oder Heizgeräte für Elektrizität, Dampf oder Gas aufweisen. Sie behandelt auch Geräte sowohl für Waschen und Trocknen (Waschtrockner) hinsichtlich ihrer auf Waschen bezogenen Funktionen. Die vorliegende Technische Spezifikation deckt von oben, von vorn und seitlich beladene, nicht für den Hausgebrauch vorgesehene Waschmaschinen mit horizontaler oder vertikaler Achse und mit einer oder mehr Waschkammer(n) ab. ANMERKUNG 1 Die Gebrauchseigenschaften von nicht für den Haushaltsgebrauch bestimmten Wäschetrocknern werden in CLC/FprTS 50594 behandelt. ANMERKUNG 2 Aufstellungen und Energieberechnungen von nicht für den Haushaltsgebrauch bestimmten Wasch¬maschinen, welche mit Gas oder Dampf beheizt werden, werden in EN ZZZZZ behandelt. Das Ziel ist die Angabe und Definition der prinzipiellen Gebrauchseigenschaften von nicht für den Haus-haltsgebrauch bestimmten Waschmaschinen, und die Beschreibung der Prüfverfahren für die Messung dieser Eigenschaften. ANMERKUNG 3 Die vorliegende Technische Spezifikation ist nicht anwendbar für Durchlaufwaschmaschinen (z. B. Tunnelwaschmaschinen) oder Waschmaschinen, welche nur mit automatischer Beladung und Entladung betrieben werden können. ANMERKUNG 4 Die vorliegende Technische Spezifikation legt keine Sicherheitsanforderungen für nicht für den Haushaltsgebrauch bestimmte Waschmaschinen fest. Sicherheitsanforderungen sind in EN 50571 und der Normenreihe EN ISO 10472 festgelegt.
