IEC 61591-2019 pdf download.Cooking fume extractors – Methods for measuring performance.
This document 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.
NOTE This document does not deal with safety requirements that are in accordance with IEC 60335-1 and IEC 60335-2-31 .
