Attention is drawn to the possibility that some of the elements of this document may be

24、the subject of patent rights. CENELEC and/or CEN 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. This document is a new Technical Specific

25、ation, but it is based on portions from EN 61121:2013. This Technical Specification is the main body of a forthcoming European Standard for measuring the performance of non-household tumble dryers. The content of this Technical Specification will be added with the Annex ZZ when the details regarding

26、 Ecodesign regulations are defined. The procedures described in this Technical Specification are modified substantially compared to the procedures described in EN 61121. Therefore, results of tests according to this Technical Specification cannot and are bound not to be compared to results of simila

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

28、e introduction of a new initial moisture level. NOTE CLC/TS 50640:2015 is planned to be a European Standard for the energy measurement of gas heated laundry equipment. A bilingual version of this publication may be issued at a later date. PD CLC/TS 50594:2015CLC/TS 50594:2015 6 1 Scope This Technica

29、l Specification is applicable to tumble dryers for commercial use of the automatic and non-automatic type, incorporating an electric or steam heating device. It also includes tumble dryers which use gas as a heating source with a reference to appropriate EN gas standards. The object is to state and

30、define the principal performance characteristics 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 dryers with automatic loading and unloading. 2 Normative references The

35、s are dried by tumbling in a rotating drum, through which air is passed 3.1.2 air vented tumble dryer tumble dryer that draws in fresh air which is passed over the textiles and where the resulting moist air is exhausted into the room or vented outside 3.1.3 condenser tumble dryer tumble dryer which

36、includes a device for removing moisture from the air used for the drying process PD CLC/TS 50594:2015 7 CLC/TS 50594:2015 3.1.4 automatic tumble dryer tumble dryer which switches off the drying process when a certain moisture content of the load is reached Note 1 to entry: This may include systems t

37、hat use conductivity or temperature sensing. 3.1.5 non-automatic tumble dryer tumble dryer which does not switch off the drying process when a certain moisture content of the load is reached, usually controlled by a timer, but may also be controlled manually 3.1.6 transfer tumble dryer tumble dryer

38、with automatic loading and unloading via conveyers or by other means Note 1 to entry: The loading and unloading conveyers are often located on opposite sides of the drying basket. 3.1.7 test load textile load used for testing 3.1.8 pre-treatment processing of a new test load prior to its first use t

39、o avoid rapid changes of characteristics during the tests 3.1.9 conditioning bringing the test load into thermodynamic equilibrium with the defined ambient air conditions of temperature and humidity Note 1 to entry: The process of conditioning is not the same as wetting which is described in 6.6.7.
