Commission Delegated Regulation (EU) No 65/2014 of 1 October 2013 supplementing Directive 2010/30/EU of the European Parliament and of the Council with regard to the energy labelling of domestic ovens and range hoods (Text with EEA relevance)
When the UK left the EU, legislation.gov.uk published EU legislation that had been published by the EU up to IP completion day (31 December 2020 11.00 p.m.). On legislation.gov.uk, these items of legislation are kept up-to-date with any amendments made by the UK since then.
This is the original version as it was originally adopted in the EU.
This legislation may since have been updated - see the latest available (revised) version
The Energy Efficiency Index (EEIhood ) is calculated as:
and is rounded to the first decimal place.
Where:
SAEChood is the Standard Annual Energy consumption of the domestic range hood in kWh/a, rounded to the first decimal place,
AEChood is the Annual Energy Consumption of the domestic range hood in kWh/a, rounded to the first decimal place.
The Standard Annual Energy Consumption (SAEChood ) of a domestic range hood shall be calculated as:
Where:
WBEP is the electric power input of the domestic range hood at the best efficiency point, in Watt and rounded to the first decimal place,
WL is the nominal electric power input of the lighting system of the domestic range hood on the cooking surface, in Watt and rounded to the first decimal place.
The Annual Energy Consumption (AEChood ) of a domestic range hood is calculated as:
for all other domestic range hoods:
Where:
tL is the average lighting time per day, in minutes (tL = 120),
tH is the average running time per day for domestic range hoods, in minutes (tH = 60),
Po is the electric power input in off-mode of the domestic range hood, in Watt and rounded to the second decimal place,
Ps is the electric power input in standby mode of the domestic range hood, in Watt and rounded to the second decimal place,
f is the time increase factor, calculated and rounded to the first decimal place, as:
The Fluid Dynamic Efficiency (FDEhood ) at the best efficiency point is calculated by the following formula, and is rounded to the first decimal place:
Where:
QBEP is the flow rate of the domestic range hood at best efficiency point, expressed in m3/h and rounded to the first decimal place,
PBEP is the static pressure difference of the domestic range hood at best efficiency point, expressed in Pa and rounded to the nearest integer,
WBEP is the electric power input of the domestic range hood at the best efficiency point, expressed in Watt and rounded to the first decimal place.
The Lighting Efficiency (LEhood) of a domestic range hood means the ratio between the average illumination and the nominal electric power input of the lighting system. It shall be calculated in lux per Watt and rounded at the nearest integer, as:
Where:
Emiddle is the average illumination of the lighting system on the cooking surface measured under standard conditions, in lux and rounded to the nearest integer,
WL is the nominal electric power input of the lighting system of the domestic range hood on the cooking surface, in Watt and rounded to the first decimal place.
The Grease Filtering Efficiency (GFEhood) of a domestic range hood means the relative amount of grease retained within the range hood grease filters. It shall be calculated and rounded to the first decimal place as:
Where:
=
the mass of oil in the grease filter, including all detachable coverings, in g and rounded to the first decimal place,
=
the mass of oil retained in the airways of the range hood, in g and rounded to the first decimal place,
=
the mass of oil retained in the absolute filter, in g and rounded to the first decimal place.
The Noise Value (in dB) is measured as the airborne acoustical A-weighted sound power emissions (weighted average value – LWA) of a domestic range hood at the highest setting for normal use, rounded to the nearest integer.
