标准摘要
[中文适用范围]: ISO 16000 的这一部分描述了使用单一示踪气体来确定当地的平均空气年龄,作为建筑物通风条件的指标。 该程序包括浓度衰减和均匀恒定发射。 所描述的方法旨在用于空气质量研究,可用于 a) 检查是否满足建筑物通风要求,b) 估计有室内空气质量问题的建筑物的通风是否充足,以及 c) 表征室内空气的强度和分布排放源。 原则上,这些方法可以应用于所有室内空间,无论使用何种通风类型以及区域之间的空气混合状态。 测量不需要干扰当前的通风条件。 ISO 16000 的这一部分不涉及示踪气体分析方法的细节。 在规划实际现场测量之前,应检查此类分析服务的可用性。 [外文原描述]: 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.
