Paragraph 4 Weighted water consumption

(1)

The weighted water consumption (W_W) of a household washing machine or of the washing cycle of a household washer-dryer must be rounded to the nearest integer and calculated in litres as follows—

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

(2)

For the purposes of sub-paragraph (1)—

(a)

W_W,full is the water consumption of—

(i)

a washing machine, or

(ii)

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;

(b)

W_W,½ is the water consumption of—

(i)

a household washing machine, or

(ii)

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;

(c)

W_W,1/4 is the water consumption of—

(i)

a household washing machine, or

(ii)

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;

(d)

A, B and C are the weighting factors referred to in paragraph 2(7).

(3)

For household washer-dryers with a rated washing capacity lower than or equal to 3 kg, the weighted water consumption of the wash and dry cycle is the water consumption at rated capacity, rounded to the nearest integer.

(4)

For all other washer-dryers, the weighted water consumption (W_WD) of the wash and dry cycle must be rounded to the nearest integer and calculated as follows—

W W D = \frac{[3 \times W W D, f u l l \pm 2 \times W W D, \frac{1}{2}]}{5}

(5)

For the purposes of sub-paragraph (4)—

(a)

W_WD,full is the water consumption of the wash and dry cycle of a household washer-dryer at rated capacity, in litres and rounded to one decimal place;

(b)

W_WD,½ is the water consumption of the wash and dry cycle of a household washer-dryer at half of the rated capacity, in litres and rounded to one decimal place.
