Division (1) The weighted water consumption (WW) of a household washing machine or the washing cycle of a household washer-dryer is calculated in litres and rounded to the nearest integer:

W_W = (A × W_W,full + B × W_W,1/2 + C × W_W,1/4)

where:

W_W,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;

W_W,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;

W_W,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).
