This European Standard specifies checks and test methods to verify the fitness for purpose of installed ventilation systems in dwellings. It can be applied to commissioning of new systems and performance testing of existing systems. The standard enables the choice between simple test methods, when sufficient, and extensive measurements, when necessary. The standard applies to mechanical and non-mechanical (natural) ventilation systems comprising any of the following: – passive stack ventilation ducts; – air terminal devices (supply, exhaust); – air transfer devices (externally mounted, internally mounted); – controls; – ducts; – fans; – filters; – heat recovery; – heating/cooling of supply air; – recirculation air; – cooker hood; – cowls; – dampers; – sound reduction devices. The standard is intended to define the procedure by which the system is checked and assessed before handling over. This standard does not apply to: – heating systems and their control; – refrigerating systems and their control; – electric power supply systems. This Standard does not include consideration of the airtightness of building envelope is in. The whole dwelling and the individual room ventilation rate can be influenced by air infiltration through the building envelope (see informative annex A). This standard does not include the effect of the ventilation system on indoor air velocity within the occupied zone although this can have an effect (see informative annex B). This standard does not include any requirements concerning the installation contract.
