Ventilation for buildings - Performance testing of components/products for residential ventilation - Part 1: Externally and internally mounted air transfer devices

Scope

This European Standard specifies laboratory methods for testing externally and internally mounted air transfer devices
operating under pressure differences.
It applies to devices located between two spaces (between one room and outside, or between two rooms) of the following
types:
-devices with fixed opening(s);
-devices with manually adjustable opening(s);
-devices with pressure difference controlled opening(s);
-window openings specifically designed to act as an air transfer device.
It describes tests intended to characterise the following:
-flow rate/pressure;
-non-reverse flow ability;
-air tightness when closed' (for closeable externally mounted air transfer device);
-geometrical free area;
-air diffusion in the occupied zone;
-sound insulation;
-water tightness.
This standard does not apply to evaluation of:
-air filtration;
-condensation risk;
-noise production.
