# Commission Regulation (EU) No 66/2014 of 14 January 2014 implementing Directive 2009/125/EC of the European Parliament and of the Council with regard to ecodesign requirements for domestic ovens, hobs and range hoods (Text with EEA relevance), Division 1: DOMESTIC OVENS

Extent: E+W+S+N.I.

The energy consumption of a cavity of a domestic oven shall be measured for one standardised cycle, in a conventional mode and in a fan-forced mode, if available, by heating a standardised load soaked with water. It shall be verified that the temperature inside the oven cavity reaches the temperature setting of the thermostat and/or the oven control display within the duration of the test cycle. The energy consumption per cycle corresponding to the best performing mode (conventional mode or fan-forced mode) shall be used in the following calculations.
For each cavity of a domestic oven, the Energy Efficiency Index (EEIcavity) shall be calculated according to the following formulas:
for domestic electric ovens:
EEIcavity=ECelectric cavitySECelectric cavity× 100SECelectric cavity=0,0042× V+ 0,55 (in kWh)
for domestic gas ovens:
EEIcavity=ECgas cavitySECgas cavity× 100SECgas cavity=0,044× V+ 3,53 (in MJ)
Where:
— EEIcavity Energy Efficiency Index for each cavity of a domestic oven, rounded to the first decimal place,
— SECelectric cavity Standard Energy Consumption (electricity) required to heat a standardised load in a cavity of a domestic electric heated oven during a cycle, expressed in kWh, rounded to the second decimal place,
— SECgas cavity Standard Energy Consumption required to heat a standardised load in a cavity of a domestic gas-fired oven during a cycle, expressed in MJ, rounded to the second decimal place,
— VVolume of the cavity of the domestic oven in litres (L), rounded to the nearest integer,
— ECelectric cavity Energy Consumption required to heat a standardised load in a cavity of a domestic electric heated oven during a cycle, expressed in kWh, rounded to the second decimal place,
— ECgas cavity Energy Consumption required to heat a standardised load in a gas-fired cavity of a domestic oven during a cycle, expressed in MJ, rounded to the second decimal place.
