Annotation of standard text ČSN EN 13141-1 (127131):

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
