Division 2.4 Calculation of the Grease Filtering Efficiency (GFEhood)

United Kingdom

The Grease Filtering Efficiency (GFE_hood) 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:

{GFE}_{hood} = [w_{g} ∕ (w_{r} + w_{t} + w_{g})] \times 100 [%]

Where:

— w_g

the mass of oil in the grease filter, including all detachable coverings, in g and rounded to the first decimal place,

— w_r

the mass of oil retained in the airways of the range hood, in g and rounded to the first decimal place,

— w_t

the mass of oil retained in the absolute filter, in g and rounded to the first decimal place.
