标准范围

ISO？16000-8:2007描述了使用单一示踪气体来确定作为建筑物通风条件指标的局部平均空气龄。程序包括浓度衰减和均匀恒定排放。所述方法用于空气质量研究，可用于检查建筑物通风要求是否得到满足，评估存在室内空气质量问题的建筑物的通风充分性，以及表征室内排放源的强度和分布。原则上，这些方法可以应用于所有室内空间，无论使用的通风类型和区域之间的空气混合状态如何。测量无需干扰主要通风条件。ISO？16000-8:2007未涉及示踪气体分析方法的细节。

ISO 16000-8:2007 describes the use of single tracer gas for determining the local mean age of air as an indicator of ventilation conditions in a building. The procedures include concentration decay and homogeneous constant emission.The described methods are intended for air quality studies and can be used for checking whether the building ventilation requirements are met, estimating the adequacy of ventilation in buildings with indoor air quality problems, and characterizing the strength and distribution of indoor emission sources.In principle, the methods can be applied to all indoor spaces, regardless of the type of ventilation used and the state of mixing of air between zones. The prevailing ventilation conditions need not be disturbed by the measurement.ISO 16000-8:2007 does not address the details of the analytical methods for tracer gases.
