Cooking fume extractors - Methods for measuring performance
IEC 61591:2019 applies to cooking fume extractors incorporating a fan for the recirculation or extraction mode situated in a household kitchen. It can also be used for cooking fume extractors where the fan is mounted separately from the appliance, but controlled by the appliance when the fan is defined in the technical documentation (e.g. name plate data) and instructions for installation. This document deals also with down-draft systems arranged beside, behind or under the cooking appliance. This document defines the main performance characteristics of these appliances, which are of interest to the user, and specifies methods for measuring these characteristics. This document does not specify a classification or ranking for performance. This document does not deal with safety requirements that are in accordance with IEC 60335-1 and IEC 60335-2-31. 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);

Extracteurs de fumée de cuisine - Méthodes de mesure de l'aptitude à la fonction
L'IEC 61591:2019 s'applique aux extracteurs de fumée de cuisine comportant un ventilateur pour le mode recyclage ou extraction, installés dans une cuisine à usage domestique. Il peut également être utilisé pour les extracteurs de fumée de cuisine lorsque le ventilateur est monté séparément de l'appareil, mais est commandé par celui-ci lorsqu'il est mentionné dans la documentation technique (données inscrites sur la plaque signalétique, par exemple) et dans les instructions d'installation. Le présent document couvre également les extracteurs verticaux installés à côté, à l'arrière ou au-dessous de l'appareil de cuisson. Le présent document définit les caractéristiques de performance principales de ces appareils qui sont pertinentes pour l'utilisateur et spécifie les méthodes de mesure de ces caractéristiques. Le présent document ne spécifie pas un système de classement pour l'aptitude à la fonction de ces appareils. Le présent document ne traite pas des exigences de sécurité qui sont conformes aux normes IEC 60335-1 et IEC 60335-2-31. Cette deuxième édition annule et remplace la première édition parue en 1997, l'Amendement 1:2005 et l'Amendement 2:2010. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente: a) ajout d'un nouveau paragraphe portant sur les instruments et les mesurages (voir 6.6); b) ajout d'une nouvelle procédure pour le mesurage du rendement dynamique des fluides (FDE, Fluid Dynamic Efficiency), suivant la proposition de principe du CENELEC; c) révision de la procédure visant à déterminer la réduction des odeurs des extracteurs de fumée de cuisine fonctionnant en mode recyclage (voir Article 12); d) modification de la procédure de mesure de l'efficacité du système d'éclairage (voir Article 11); e) clarification de la procédure de mesure de l'absorption des graisses (voir Article 13).

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 Com
