  "heading": "Energy Efficiency Index (EEIW) of household washing machines and the washing cycle of household washer-dryers",
  "text": "For the calculation of the EEIW, the weighted energy consumption of the eco 40-60 programme at the rated washing capacity, half of the rated washing capacity and a quarter of the rated washing capacity is compared to its standard cycle energy consumption.\n(a)The EEIW is calculated as follows, and is rounded to one decimal place:\nEEIW = (EW/SCEW) × 100\nwhere:\nEW is the weighted energy consumption of the household washing machine or of the washing cycle of the household washer-dryer;\nSCEW is the standard cycle energy consumption of the household washing machine or the washing cycle of the household washer-dryer.\n(b)The SCEW is calculated in kWh per cycle as follows, and is rounded to three decimal places:\nSCEW = -0,0025 × c2 + 0,0846 × c + 0,392\nwhere c is the rated capacity of the household washing machine or the rated washing capacity of the household washer-dryer for the eco 40-60 programme.\n(c)The EW is calculated in kWh per cycle as follows, and is rounded to three decimal places:\nwhere:\nEW,full is the energy consumption of the household washing machine or of the washing cycle of the household washer-dryer for the eco 40-60 programme at the rated washing capacity and rounded to three decimal places;\nEW,½ is the energy consumption of the household washing machine or of the washing cycle of the household washer-dryer for the eco 40-60 programme at half of the rated washing capacity and rounded to three decimal places;\nEW,1/4 is the energy consumption of the household washing machine or of the washing cycle of the household washer-dryer for the eco 40-60 programme at a quarter of the rated washing capacity and rounded to three decimal places;\nA is the weighting factor for the rated washing capacity and rounded to three decimal places;\nB is the weighting factor for half of the rated washing capacity and rounded to three decimal places;\nC is the weighting factor for a quarter of the rated washing capacity and rounded to three decimal places;\nfor household washing machines with a rated capacity lower than or equal to 3 kg and for household washer-dryers with a rated washing capacity lower than or equal to 3 kg, A shall be equal to 1; B and C shall be equal to 0;\nfor other household washing machines and household washer-dryers, the values of the weighting factors depend on the rated capacity according to the following equations:\nA = -0,0391 × c + 0,6918\nB = -0,0109 × c + 0,3582\nC = 1 - (A + B)\nwhere c is the rated capacity of the household washing machine or the rated washing capacity of the household washer dryer.",
