BS EN 13141-9:2008

This standard BS EN 13141-9:2008 Ventilation for buildings. Performance testing of components/products for residential ventilation is classified in these ICS categories:

• 91.140.30 Ventilation and air-conditioning systems

This European Standard specifies laboratory methods for testing humidity controlled air inlets operating under pressure differences. It applies to all devices located between one room and outside and controlled on indoor humidity. For instance, devices of the following types: humidity controlled devices with fixed setting; manually openable or closable humidity controlled devices; humidity controlled devices self-adjusting on pressure difference. It describes tests intended to characterise: aero and hygro-dynamic performance; air tightness when closed (for closable humidity controlled air inlet); air diffusion in the occupied zone; sound insulation; time response. This European Standard does not apply to the evaluation of air filtration, condensation risk and noise production.
