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.
