ISO 9972:2015旨在测量现场建筑物或部分建筑物的透气性。它规定了建筑物或建筑物部分的机械增压或减压的使用。它描述了室内外静压差范围内产生的空气流量的测量。 ISO 9972:2015旨在测量单区建筑围护结构的空气泄漏。就本国际标准而言，许多多区域建筑可通过打开室内门或在相邻区域内产生相等压力，被视为单区域建筑。 ISO 9972:2015未涉及单个部件透气性的评估。

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.
