This standard defines a general laboratory test method for determining the air permeability of building components or building elements, when subjected to positive or negative air pressure differences. It specifies the definitions, the test equipment and procedure, and provides directions for the interpretation of results.
Annexes give indications on test conditions and a method for expressing results using a regression technique.
This standard is not applicable to whole buildings or on site measurements.
