Summary :
This International Standard is intended for the measurement of the air permeabilit y 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 f low rates over a range of indoor-outdoor static pressure differences. This International Standard is intended for the measurement of the air leakage of building envelopes of single-zone buildings. For the purpose of this International Standard, many multi-zone buildings can be treated as single-zone buildings by opening interior doors or by inducing equal pressures in adjacent zones. International Standard does not address evaluation of air permeabilit y of individual components.
