This European Standard was approved by CENELEC on 2007-06-01. CENELEC members are bound to comply with the CEN/CENELEC Internal Regulations which stipulate the conditions for giving this European Standard the status of a national standard without any alteration.
Up-to-date lists and bibliographical references concerning such national standards may be obtained on application to the Central Secretariat or to any CENELEC member.
This European Standard exists in three official versions (English, French, German). A version in any other language made by translation under the responsibility of a CENELEC member into its own language and notified to the Central Secretariat has the same status as the official versions.
CENELEC members are the national electrotechnical committees of Austria, Belgium, Bulgaria, Cyprus, the Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, the Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and the United Kingdom.

The text of the draft was submitted to the Unique Acceptance Procedure and was approved by CENELEC as EN 50229 on 2007-06-01. This European Standard supersedes EN 50229:2001. The following dates were fixed: – latest date by which the EN has to be implemented at national level by publication of an identical national standard or by endorsement
(dop)
2008-06-01 – latest date by which the national standards conflicting with the EN have to be withdrawn
(dow)
2010-06-01 It is based on the EN 50229:2001 taking into account the current versions of EN 60456:2005 and EN 61121:2005. Significant technical differences to the revised second edition, EN 50229:2001, are: • revised referring to revised EN 60456; • revised referring to revised EN 61121. This European Standard has been prepared under a mandate given to CENELEC by the European Commission and the European Free Trade Association and covers essential requirements of EC Directive 96/60/EC implementing Council Directive 92/75/EEC on ”Indication by labelling and standard product information of the consumption of energy and other resources by household appliances“. It deals only with those test procedures that are required for the EC Directive as described in the scope of this standard. It also defines permitted tolerances to values declared by the manufacturer and control procedures for checking these values. _____________

- 5 - EN 50229:2007 3 Definitions For the purpose of this document, the terms and definitions in Clause 3 of EN 60456 apply, except for 3.1.12 and 3.1.13. Additional definitions: 3.101 rated washing capacity maximum mass of conditioned textiles (conditioned according to Subclause 6.3.3 in EN 60456), in kg, which the manufacturer declares can be treated in one complete washing cycle 3.102 rated drying capacity maximum mass of conditioned textiles (conditioned according to Subclause 6.3.3 in EN 60456), in kg, which the manufacturer declares can be treated in one complete single drying operation 3.103 complete operation cycle complete washing and drying process, as defined by the required programme(s), consisting of a the washing cycle and the drying cycle 3.104 washing cycle complete washing process, as defined by the required programme, consisting of a series of different operations (wash, rinse, spin) 3.105 drying cycle complete drying process, as defined by the required programme, consisting of a series of different operations (heat, cool down). The drying cycle comprise drying of all partial loads, if the base load is split up according to 9.4.3.2 – c) 3.106 automatic drying drying process which automatically switches off when a certain moisture content of the load is reached 4 External dimensions See Subclause 3.3 of EN 60456. 5 Range of rated capacity The rated capacity for measurements to determine values to be declared for the 60 °C cotton cycle according to the Commission’s Directive on energy labelling is the value declared by the manufacturer as highest amount of cotton textiles to be washed, given in the instruction manual or on the energy label supplied with the machine, whatever is higher. If the rated capacity is not declared, the rated capacity for a cotton load shall be deduced from the volume of the drum according to the following ratio: – horizontal drum washing machine 1 kg / 13 l.

- 7 - EN 50229:2007 9.4 Determination of the water and energy consumption and programme time 9.4.1 General This clause specifies the procedure and evaluation for the determination of water and energy consumption during washing, spin extraction and drying. It also specifies the method for the determination of the duration of these cycles and of the complete operating cycle. NOTE The tests in this clause may be combined with the tests in 9.1 and 9.2. 9.4.2 Washing cycle The measurement shall be carried out in accordance with Subclause 5.1 and Clause 11 of EN 60456. 9.4.3 Drying cycle 9.4.3.1 General The mass of the conditioned base load is recorded as W0. The number of valid drying cycles shall be five. 9.4.3.2 Procedure a) A washing cycle shall be performed according to 9.1. b) Immediately when the washing cycle is finished the strips are removed from the test load and the initial mass of the base load is recorded in kg as Wi. The actual initial moisture content is calculated as: 10000×−=WWWiiµ (1) where µI is the actual initial moisture content, Wi
is the actual initial mass of the base load after the washing cycle, W0
is the mass of the conditioned base load. c) The base load Wi shall be dried under the conditions specified below (dry cotton) to nominal final moisture content µfo = 0 %, allowable range for µfo: -3 % to +3 %.
[Table 3 in Subclause 9.2.1 of EN 61121] 1) The base load shall be divided according to the instruction of the manufacturer. If no instruction is given and the rated drying capacity is lower than the rated washing capacity, the base load is divided in nearly equal partial loads each part not being above the rated drying capacity. The division of the base load shall be according to Annex A. In this case all items of the base load shall be marked before starting the washing cycle, in order to identify to which partial load each item belongs. The partial loads shall consist of the same items throughout the test. 2) Within 5 min after finishing the washing cycle the drying of the first partial load has to be started. The other partial load(s) shall be kept in (a) closed plastic bag(s). For washer-dryers with automatic drying the programme under test is selected and the washer dryer is started. For washer-dryers without automatic drying the timer is set to obtain the final moisture given above under c). The time required for this is determined by monitoring the drying process. This can be done by either having the washer dryer placed on a platform scale or by pre-testing.
