SCHEDULE 7Measurement methods and calculations for household dishwashers
Energy efficiency index2
1
The EEI is determined as follows.
2
For all household dishwasher models, the EEI is calculated by comparing the eco programme energy consumption at rated capacity (“EPEC”) of the dishwasher to its standard programme energy consumption (“SPEC”).
3
The EEI must be rounded to one decimal place and is calculated as follows—
EEI = (EPEC/SPEC) × 100.
4
For the purposes of sub-paragraph (3)—
a
EPEC and SPEC are measured in kWh/cycle and rounded to three decimal places;
b
SPEC is calculated as follows—
i
for household dishwashers with rated capacity ps ≥ 10 and width > 50 cm—
SPEC = 0.025 × ps + 1.350;
ii
for household dishwashers with rated capacity ps ≤ 9 or width ≤ 50 cm—
SPEC = 0.090 × ps + 0.450;
where ps is the number of place settings.
