The following dates are fixed: latest date by which this document has to be implem

31、ented at national level by publication of an identical national standard or by endorsement (dop) 2019-04-23 latest date by which the national standards conflicting with this document have to be withdrawn (dow) 2021-04-23 This document supersedes CLC/TS 50594:2015. This document is based on portions

32、of EN 61121:2013. The procedures described in this European Standard are modified substantially compared to the procedures described in EN 61121. Therefore, results of tests according to this European Standard cannot and are bound not to be compared to results of similar procedures of EN 61121. Sign

33、ificant technical differences from EN 61121 are: a) test procedures for tumble dryers of any size on the market; b) test procedure for measuring power consumption also for steam heated and gas heated tumble dryers; c) the introduction of a new type of test load; d) the introduction of a new initial

34、moisture content level. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. 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 E

BS EN 50594:2018EN 50594:2018 (E) 6 1 Scope This European Standard is applicable to tumble dryers intended to be used by trained users e.g. in hotels, hospitals, factories, in light industry and on farms. It covers tumble dryers declared fo

36、r commercial use in public areas and operated by lay persons e.g. in launderettes, apartment houses and communal laundry rooms. This European Standard covers tumble dryers which use electricity, gas or steam as a heating source. The object is to state and define the principal performance characteris

37、tics of tumble dryers for commercial use of interest to users and to describe standard methods for measuring these characteristics. NOTE It does not apply to transfer tumble dryers or tumble dryers only possible to operate with automatic loading and unloading. 2 Normative references The following do
