(Main)Fans - Performance testing of jet fans (ISO/DIS 13350:2025)
Fans - Performance testing of jet fans (ISO/DIS 13350:2025)
ISO 13350:2015 deals with the determination of those technical characteristics needed to describe all aspects of the performance of jet fans as defined in ISO 13349. It does not cover those fans designed for ducted applications, nor those designed solely for air circulation, e.g. ceiling fans and table fans.
The test procedures described in this International Standard relate to laboratory conditions. The measurement of performance under on-site conditions is not included.

Ventilateurs - Essai de performance des ventilateurs accélérateurs (ISO/DIS 13350:2025)
L'ISO 13350:2015 traite de la détermination des caractéristiques techniques qui sont nécessaires pour décrire tous les aspects de la performance des ventilateurs accélérateurs tels que définis dans l'ISO 13349. Elle ne couvre pas les ventilateurs destinés aux applications en conduit ni ceux destinés uniquement à la circulation de l'air, par exemple les ventilateurs de plafond et de table.
