Scope:

1.1           This is a method for the determination of the airtightness of building envelopes. It is not a method for determining the actual air leakage which occurs through a building  envelope under the influence of wind and buoyancy  pressures or the operation of heating and ventilation systems.

 

1.2           The method is applicable  to small detached buildings  (especially  houses) but with appropriate modifications,  it can also be used for     other buildings or part of buildings.
