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

ISO 9972:2015 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 9972:2015 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.ISO 9972:2015 does not address evaluation of air permeability of individual components.

Le présent document est utilisé pour mesurer la perméabilité à l'air de l'enveloppe ou de certaines parties de bâtiments in situ. Il spécifie la mise en oeuvre d'une pressurisation ou d'une dépressurisation mécanique d'un bâtiment ou d'une partie d'un bâtiment. Il décrit le mesurage des débits d'air qui en résultent dans une plage de différences de pression statique intérieur-extérieur. Il est utilisé pour mesurer les fuites d'air des enveloppes de bâtiments monozone. Il ne traite pas de l'évaluation de la perméabilité à l'air des divers composants.

ZOOM ON ... the Requirements department
To comply with a standard, you need to quickly understand its issues in order to determine its impact on your activity.

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.

The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.
