3.—(1) For the calculation of the EEIWD of a household washer-dryer model, the weighted energy consumption of the wash and dry cycle at—
(a)the rated capacity; and
(b)half of the rated capacity;
must be compared to its standard cycle energy consumption.
(2) The EEIWD must be rounded to one decimal place and calculated as follows—
EEIWD = (EWD/SCEWD) × 100.
(3) For the purposes of sub-paragraph (2)—
(a)EWD is the weighted energy consumption of the complete cycle of the household washer-dryer;
(b)SCEWD is the standard cycle energy consumption of the complete cycle of the household washer-dryer.
(4) The SCEWD must rounded to three decimal places and calculated in kWh per cycle as follows—
SCEWD = -0.0502 × d2 + 1.1742 × d - 0.644.
where d is the rated capacity of the household washer-dryer for the wash and dry cycle.
(5) For household washer-dryers with a rated washing capacity lower than or equal to 3 kg, the weighted energy consumption is the energy consumption at rated capacity, rounded to three decimal places.
(6) For other household washer-dryers, the weighted energy consumption (EWD) must be rounded to three decimal places and calculated in kWh per cycle as follows—
3
(7) For the purposes of sub-paragraph (6)—
(a)EWD,full is the energy consumption of the household washer-dryer for the wash and dry cycle at rated capacity, rounded to three decimal places;
(b)EWD,½ is the energy consumption of the household washer-dryer for the wash and dry cycle at half of the rated capacity, rounded to three decimal places.
(8) The washing efficiency index of household washing machines and the washing cycle of household washer-dryers (IW) and the washing efficiency index of the complete cycle of household washer-dryers (JW) must be rounded to three decimal places.
(9) The rinsing effectiveness of household washing machines and of the washing cycle of household washer-dryers (IR) and the rinsing effectiveness of the complete cycle of household washer-dryers (JR) must based on the detection of the linear alkylbenzene sulfonate (LAS) marker, and rounded to one decimal place.
(10) The maximum temperature reached for 5 minutes inside the laundry being treated in household washing machines and the washing cycle of household washer-dryers must be rounded to the nearest integer.
