This European Standard deals with the performance of clothes washing machines intended to be used by trained users e.g. in hotels, hospitals, factories, in light industry and on farms. It also covers washing machines declared for commercial use in public areas and operated by lay persons e.g. in launderettes, apartment houses and communal laundry rooms. The clothes washing machines can be utilizing cold and/or hot water supply and without heating or with heating devices for electricity, steam or gas. This European Standard covers top, front and side loaded clothes washing machines with horizontal or vertical axis and with one or more wash compartments. It also deals with appliances for both washing and drying textiles (washer-dryers) with respect to their washing related functions and to separate spin extractors related to their dewatering capabilities. NOTE 1 Performance of tumble dryers declared for commercial use is assessed in EN 50594. NOTE 2 The object is to state and define the principal performance characteristics of clothes washing machines declared for commercial use and to describe the test methods for measuring these characteristics. NOTE 3 This European Standard 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 European Standard does not specify safety requirements for clothes washing machines declared for commercial use. Safety requirements are specified in EN 50571 and the EN ISO 10472- series.
