27、2018) has been prepared by CLC/TC 59X “Performance of household and similar electrical appliances”. The following dates are fixed: latest date by which this document has to be implemented at national level by publication of an identical national standard or by endorsement (dop) 2019-04-23 latest dat
28、e by which the national standards conflicting with this document have to be withdrawn (dow) 2021-04-23 This document supersedes CLC/TS 50640:2015. This European Standard is a new standard, but it is based on portions from EN 60456:2011. The procedures described in this European Standard are modified
29、 substantially compared to the procedures described in EN 60456. Therefore results of tests according to this European Standard cannot and are bound not to be compared to results of similar procedures of EN 60456. Significant technical differences from EN 60456 are: a) the method includes procedures
30、 for measuring steam heated and gas heated washing machines; b) the introduction of a new type of base load; c) a new reference programme; d) a new formulation of the standard detergent. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rig
31、hts. CENELEC shall not be held responsible for identifying any or all such patent rights. This document has been prepared under a mandate given to CENELEC by the European Commission and the European Free Trade Association. BS EN 50640:2018EN 50640:2018 (E) 5 1 Scope This European Standard deals with
32、 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 c
33、ommunal 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
34、 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
35、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 wash
36、ing 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
37、ISO 10472- series. 2 Normative references The following documents are referred to in the text in such a way that some or all of their content constitutes requirements of this document.
