scope:

This European Standard specifies checks and test methods in order 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 handing over (see Figure 1).
