EN 13141-1:2019

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.
