3 Terms, definitions and symbols
3.1 Terms and definitions
For the purposes of this document, the terms and definitions given in 3.1 of EN 60456:2011, except
for 3.1.15, 3.1.22, 3.1.25, 3.1.Z1 – 3.1.Z12, together with the following apply.
3.1.1
washer-dryer
washing machine which includes both a spin extraction function and also a means for drying the
textiles, usually by heating and tumbling
3.1.2
rated washing capacity
maximum mass in kg of dry textiles which the manufacturer declares can be washed in the washer-
dryer
3.1.3
rated drying capacity
maximum mass in kg of dry textiles which the manufacturer declares can be dried in the washer-
dryer
3.1.4
complete operation cycle
complete washing and drying process, as defined by the required programmes, consisting of a
washing cycle and a drying cycle set
3.1.5
washing cycle
complete washing process, as defined by 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 rated 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 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 the 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 drying load or residual drying load.
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 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 drying 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 rated 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 fails to achieve a
final moisture content of 3,0 % or less
3.2 Symbols
The symbols used in this standard are listed in Table 1.
NOTE The symbols in 3.2 of EN 60456:2011 and 3.2 of EN 61121:2013 do not apply to this European
