ISO 9972:2006

Thermal performance of buildings -- Determination of air permeability of buildings -- Fan pressurization method

ISO 9972:2006 is intended for the measurement of the air permeability of buildings or parts of buildings in the field. It specifies the use of mechanical pressurization or depressurization of a building or part of a building. It describes the measurement of the resulting air flow rates over a range of indoor-outdoor static pressure differences.

ISO 9972:2006 is intended for the measurement of the air leakage of building envelopes of single-zone buildings. For the purpose of ISO 9972:2006, many multi-zone buildings can be treated as single-zone buildings by opening interior doors or by inducing equal pressures in adjacent zones.

ISO 9972:2006 does not address evaluation of air permeability through individual components.
