28、the required programme, consisting of a series of different operations (wash, rinse, spin) 3.1.6 drying cycle complete drying process, as defined by the required programme, consisting of a series of different operations (heat, spin, cool down) 3.1.7 drying cycle set set of drying cycles in which a r
29、ated drying load and a residual drying load are dried Note 1 to entry: Usually a drying cycle set consists of two or more drying cycles involving the rated drying load and the residual drying load but when a washer-dryer has a rated drying capacity equal to its rated washing capacity the term drying
30、 cycle set applies to the cycle in which the rated drying load is dried. 3.1.8 automatic drying drying process which automatically switches off when a certain moisture content of the load is reached 3.1.9 partial load part of the test load used during a single drying cycle Note 1 to entry: Usually t
31、he rated drying capacity of a washer-dryer is smaller than its rated washing capacity. In this case, for a complete operating cycle the test load for washing has to be divided into partial loads to perform the drying tests. Note 2 to entry: Partial load is a general term that means either rated dryi
32、ng load or residual drying load. BS EN 50229:2015EN 50229:2015 (E) - 6 - Note 3 to entry: If, for a particular washer-dryer the rated drying capacity is equal to the rated washing capacity, the term partial load means the entire base load. 3.1.10 rated drying load part of the base load having a mass
33、 after conditioning equal to the rated drying capacity of the washer-dryer except for the case where the rated drying capacity is equal to the rated washing capacity in which case the rated drying load shall have the same mass as the base load Note 1 to entry: Under circumstances where the rated dry
34、ing capacity is less than half the rated washing capacity, more than one rated drying load will need to be prepared from the base load. 3.1.11 residual drying load remaining part of the base load after the rated drying load(s) has been removed Note 1 to entry: If, for a particular washer-dryer the r
35、ated drying capacity is equal to the rated washing capacity, there will be no residual drying load. 3.1.12 final moisture content moisture content of a test load at the end of a drying cycle 3.1.13 additional drying supplementary drying of the test load applied when the selected drying programme fai

42、nsumption for drying; Energy consumption for washing; Energy consumption for drying; Programme time for washing; Programme time for drying; Maximum spin speed. NOTE While this document describes the general procedure for the measurement of these parameters, much of the necessary and specific detail
43、is contained in EN 60456:2011 and EN 61121:2013.

The rated drying capacity shall be declared by the manufacturer or supplier as the maximum mass of cotto
46、n textiles, to be dried in either a drying only cycle or a combined washing and drying cycle without interruption, whichever is higher, at 0,5 kg intervals given in any user information. The rated drying capacity for any textile type shall not exceed the maximum mass of dry laundry, in kilograms, to
47、 be used in the washer-dryer in accordance with 3.1.9 of EN 60335-2-11:2010.
