建筑物热性能.空气渗透率的测定.风扇增压法(ISO 9972:2015)

[中文适用范围]： 本国际标准适用于建筑物或建筑物部分的透气性的现场测量。它规定了在建筑物或建筑物部分中机械产生的正压或负压的使用。它描述了根据内部和外部之间的各种静压差来测量空气体积流量。本国际标准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，许多多区域建筑物可以通过打开内门或在相邻区域产生相等的压力来视为单区域建筑物。国际标准不涉及单个组件透气性的测定。 [外文原描述]： 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.
