24、this document may be 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 n

25、ew Technical Specification, 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

26、the details regarding 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

27、 to results of similar 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 typ

28、e of base load; d) the 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

29、1 Scope This Technical 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 ob

30、ject is to state and 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 Norm
