COOKING FUME EXTRACTORS –
METHODS FOR MEASURING PERFORMANCE
FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
Publicly Available Specifications (PAS) and Guides (hereafter referred to as "IEC Publication(s)"). Their
preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
may participate in this preparatory work. International, governmental and non-governmental organizations liaising
with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence between
any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent
rights. IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 61591 has been prepared by subcommittee 59K: Performance of
household and similar electrical cooking appliances, of IEC technical committee 59:
Performance of household and similar electrical appliances.
This second edition cancels and replaces the first edition published in 1997, Amendment 1:2005
and Amendment 2:2010. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) new subclause about instruments and measurements (see 6.6);
b) new procedure for measuring the fluid dynamic efficiency (FDE), which follows the
CENELEC proposal in principle;
c) revised procedure for determining the odour reduction for cooking fume extractors in
recirculation mode (see Clause 12);
d) modification to the measurement of the effectiveness of the lighting system (see Clause 11);
e) clearer procedure to measure the grease absorption (see Clause 13);

4 Classification
According to the mode:

5 List of measurements
Performance is determined by assessing the following:
– overall dimensions;
– mass;
– power measurement of low-power modes;
– airborne acoustical noise;
– volumetric airflow;
– effectiveness and electric power input of the lighting system;
– ability to reduce odours;
– ability to absorb grease.
6 General conditions for measurements
6.1 Test room
The tests are carried out in a draught-free room. The ambient temperature of the room is
maintained at (23 ± 2) °C. The absolute air pressure shall be between 913 hPa and 1 063 hPa.
6.2 Installation and positioning
The appliance has to be clean and free of any residues of packaging material and protective
foil. All tests have to be carried out following the order of the clauses of this document with one
and the same appliance.
The cooking fume extractor (except for the down-draft system) is installed above a cooking
appliance with the distance of (600 ± 10) mm. The distance is determined between the lowest
level of the cooking fume extractor and the highest level of the cooking appliance. The cooking
fume extractor is installed and operated in accordance with the manufacturer’s instructions
(except for the distance above the cooking appliance).

SIST EN IEC 61591:2020
– 10 – IEC 61591:2019 © IEC 2019
Any extendible visor, which is extendable for normal use in accordance with the manufacturer’s
instructions, shall be opened accordingly. If no instructions are given, the extendible visor is
fully opened.
If the down-draft system can be elevated, the manufacturer’s instructions are followed;
otherwise, it shall be measured in its maximum elevated position for use.
The maximum sized duct in accordance with the manfacturer’s instructions is to be used.
For all tests, the appliance is operated with unchanged default factory settings (e.g. brightness
of the display or changeable light colour). Supplementary parts that are part of the appliance
are mounted in accordance with the manufacturer’s instructions. Ensure that no network is
connected to the appliance for the duration of the measurement, except for the remote control.
Before the measurement is made, any conditioning of the cooking fume extractor, unless
explicitly required in this document, is not allowed.
Ensure that any automatic modes, where the fan speed is altered, are switched off.
6.3 Electricity supply
The cooking fume extractor is supplied at the rated voltage ±1 %.
If the appliance has a rated voltage range, the tests are carried out at the nominal voltage of
the country where the appliance is intended to be used.
The supply frequency shall be at the rated frequency ±1 % throughout the test. If a frequency
range is indicated, then the test frequency shall be that of the nominal frequency of the country
in which the appliance is intended to be used.
6.4 Filters
For all tests, it shall be ensured that all filters are positioned correctly.
For appliances with more than one grease filter, the filters shall be positioned with no gap in
between (centrally positioned).
6.5 Fan control
Cooking fume extractors shall be tested in the highest continuous setting for normal use,
as stated in the manufacturer’s instructions.
6.6 Instrumentation and measurements
Instruments used and measurements made for this document shall comply with the
specifications in Table 1 and Table 2. The accuracy is applied to the measured value.

7 Dimensions and mass
7.1 Overall dimensions
The overall dimensions of the cooking fume extractor are measured. The longest width, depth
and height, including any control knobs or other projections, are stated in millimetres rounded

use, then the minimum and maximum sizes are stated.
For cooking fume extractors with extraction mode, the dimensions of the air-outlet orifice
are measured and stated.
7.2 Distance between cooking fume extractor and cooking appliance
The shortest distance between the lowest level of the cooking fume extractor, except down-
draft systems, and the highest level of the cooking appliance is measured and indicated in
millimetres, rounded to 10 mm.
