  "text": "(1) For the calculation of the EEIW, the weighted energy consumption of the eco 40-60 programme at—\n(a) the rated washing capacity;\n(b) half of the rated washing capacity; and\n(c) one quarter of the rated washing capacity;\nmust be compared to its standard cycle energy consumption.\n(2) The EEIW must be rounded to one decimal place and calculated as follows—\nEEIW = (EW/SCEW) × 100.\n(3) For the purposes of sub-paragraph (2)—\n(a) EW is the weighted energy consumption of the household washing machine or of the washing cycle of the household washer-dryer;\n(b) SCEW is the standard cycle energy consumption of the household washing machine or the washing cycle of the household washer-dryer.\n(4) The SCEW must be rounded to three decimal places and calculated in kWh per cycle as follows—\nSCEW = -0.0025 × c2 + 0.0846 × c + 0.3920.\n(5) For the purposes of sub-paragraph (4), c is—\n(a) the rated capacity of the washing machine; or\n(b) the rated washing capacity of the washer-dryer;\nfor the eco 40-60 programme.\n(6) The EW must be rounded to three decimal places and calculated in kWh per cycle as follows—\nEw=A×Ew,full±B×Ew, 1 2 ±C×Ew 1 4\n(7) For the purposes of sub-paragraph (6)—\n(a) EW,full is the energy consumption of—\n(i) the washing machine; or\n(ii) the washing cycle of the household washer-dryer;\nfor the eco 40-60 programme at the rated washing capacity, rounded to three decimal places;\n(b) EW,½ is the energy consumption of—\n(i) household washing machine; or\n(ii) the washing cycle of the household washer-dryer;\nfor the eco 40-60 programme at half of the rated washing capacity, rounded to three decimal places;\n(c) EW,1/4 is the energy consumption of—\n(i) the washing machine; or\n(ii) the washing cycle of the household washer-dryer;\nfor the eco 40-60 programme at a quarter of the rated washing capacity, rounded to three decimal places;\n(d) A is the weighting factor for the rated washing capacity and rounded to three decimal places;\n(e) B is the weighting factor for half of the rated washing capacity and rounded to three decimal places;\n(f) C is the weighting factor for a quarter of the rated washing capacity and rounded to three decimal places;\n(g) for washing machines with a rated capacity lower than or equal to 3 kg and washer-dryers with a rated washing capacity lower than or equal to 3 kg—\n(i) A is equal to 1;\n(ii) B and C are be equal to 0;\n(h) for other washing machines and washer-dryers, the values of the weighting factors depend on the rated capacity according to the following equations—\n(i) A = -0.0391 × c + 0.6918;\n(ii) B = -0.0109 × c + 0.3582;\n(iii) C = 1 - (A + B);\nwhere c is the rated capacity of the washing machine or the rated washing capacity of the washer dryer.",
