Overview
IEC 60704-2-13:2023 is an international standard published by the International Electrotechnical Commission (IEC) that specifies test methods for determining airborne acoustical noise emitted by cooking fume extractors used in households and similar environments. This latest fourth edition supersedes the 2016 release and introduces a technical revision aligning it with recent standards such as IEC 61591:2023 and IEC 60704-1:2021.
The standard applies to cooking fume extractors, including range hoods, down-draft systems, and built-in extractor units. It covers extractors intended to filter air inside a room or exhaust air outside, whether the fan is directly attached or mounted separately but controlled by the appliance. Notably, this document focuses solely on noise emissions within the room from which fumes are extracted, excluding noise along external ducts or outside the premises.
By providing consistent measurement conditions and methods, IEC 60704-2-13:2023 enables manufacturers, testing labs, and regulatory bodies to reliably assess and compare the acoustical noise performance of household cooking fume extractors.
