This document specifies laboratory methods for testing externally and internally mounted air transfer devices operating under pressure differences. This document applies to air transfer devices of the following types: – air transfer devices with fixed opening(s); – air transfer devices with manually adjustable opening(s); – air transfer devices with pressure difference controlled opening(s); – window openings specifically designed to act as an air transfer device. This document describes tests intended to characterize the following: – flow rate\/pressure; – equivalent area – reverse flow ability; – air tightness when closed; – free area; – air diffusion in the occupied zone; – sound insulation; – water tightness. This document does not apply to evaluation of: – air filtration; – condensation risk; – noise production.<\/p>\n
