33、15) has been prepared by CLC/TC 59X “Performance of household and similar electrical appliances“. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CENELEC and/or CEN shall not be held responsible for identifying any or all such pa-
34、 tent rights. This document has been prepared under a mandate given to CENELEC by the European Commission and the European Free Trade Association. This is a new Technical Specification, but it is based on portions from EN 60456:2011. This Technical Specification is the main body of a forthcoming Eur
35、opean Standard for measuring the performance of non-household washing machines. The content of this Technical Specification will be added with the Annex ZZ when the details regarding Ecodesign regulations are defined. The procedures described in this Technical Specification are modified substantiall
36、y compared to the procedures described in EN 60456. Therefore, results of tests according to this Technical Specification cannot and are bound not to be compared to results of similar procedures of EN 60456. Significant technical differences from EN 60456 are: a) test procedures for washing machines
37、 of any size on the market; b) the method includes procedures for measuring steam heated and gas heated washing machines; c) the introduction of a new type of base load; d) a new reference programme. NOTE CLC/TS 50640:2015 is planned to be a European Standard for the energy measurement of gas heated
38、 laundry equipment. A bilingual version of this publication may be issued at a later date. PD CLC/TS 50640:2015 7 CLC/TS 50640:2015 1 Scope This Technical Specification specifies methods for measuring the performance of clothes washing machines for commercial use utilizing cold and/or hot water supp
39、ly and without heating or with heating devices for electricity, steam or gas. It also deals with appliances for both washing and drying textiles (washer-dryers) with respect to their washing related functions. This Technical Specification covers top, front and side loaded non household washing machi
40、nes with horizontal or vertical axis and with one or more wash compartments. NOTE 1 Non household tumble dryer performance is assessed to CLC/TS 50594. The object is to state and define the principal performance characteristics of non-household washing machines and to describe the test methods for m
41、easuring these characteristics. NOTE 2 This Technical Specification 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 3 This Technical Specification does not specify safety requirements fo
42、r non-household washing machines. Safety requirements are specified in EN 50571 and the EN ISO 10472 series. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
