AS/NZS ISO 9972:2015 Thermal performance of buildings - Determination of air permeability of buildings - Fan pressurization method
Standards Australia/Standards New Zealand
The objective of this Standard is to provide measurement of the air permeability of buildings or parts of buildings in the field to validate the designed thermal performance. 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. This Standard also provides measurement of the air leakage of building envelopes of single-zone buildings.
This Standard is identical with, and has been reproduced from ISO 9972:2015, Thermal performance of buildings—Determination of air permeability of buildings—Fan pressurization method.
As this Standard is reproduced from an International Standard, the following applies:
(a) In the source text ‘this International Standard’ should read ‘this Australian/New Zealand Standard’.
(b) A full point substitutes for a comma when referring to a decimal marker.
None of the normative references in the source document have been adopted as Australian or Australian/New Zealand Standards.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO will not be held responsible for identifying any or all such patent rights.
The term ‘informative’ has been used in this Standard to define the application of the annex to which it applies. An ‘informative’ annex is only for information and guidance.

This International Standard 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.
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 permeability of individual components.
