Extent: E+W+S+N.I.

WW = (A × WW,full + B × WW,1/2 + C × WW,1/4)
where:
WW,full is the water consumption of the household washing machine or of the washing cycle of a household washer-dryer for the eco 40-60 programme at rated washing capacity, in litres and rounded to one decimal place;
WW,½ is the water consumption of the household washing machine or of the washing cycle of a household washer-dryer for the eco 40-60 programme at half of the rated washing capacity, in litres and rounded to one decimal place;
WW,1/4 is the water consumption of the household washing machine or of the washing cycle of a household washer-dryer for the eco 40-60 programme at a quarter of the rated washing capacity, in litres and rounded to one decimal place;
A, B and C are the weighting factors as described in point 2.1(c).
