BS EN ISO 9972:2015旨在测量建筑物或建筑物的空气渗透性 现场建筑的一部分。它规定了机械增压或减压的使用 建筑物或建筑物的一部分。它描述了在一定范围内测量产生的空气流量 室内外静压差的测量。本国际标准旨在测量建筑物围护结构的空气泄漏 单区建筑。就本国际标准而言，许多多区域建筑可以 通过打开内部门或在相邻区域内产生相等的压力，将其视为单区建筑 区域。国际标准不涉及单个部件透气性的评估。交叉引用:ISO 7345购买本文件时可获得的所有现行修订均包含在购买本文件中。

BS EN 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.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.Cross References:ISO 7345All current amendments available at time of purchase are included with the purchase of this document.
