标准范围

ISO 12569:2017建立了使用示踪气体获得建筑空间（被视为单一区域）通风率或特定气流率的方法。测量方法适用于满足示踪气体浓度均匀性、废气浓度测量、有效混合区和/或通风波动等综合条件的空间。ISO 12569:2017提供了三种使用示踪气体的测量方法:浓度衰减法、连续剂量法和恒定浓度法。注:表1给出了具体的测量条件。

ISO 12569:2017 establishes methods to obtain the ventilation rate or specific airflow rate in a building space (which is considered to be a single zone) using a tracer gas.The measurement methods apply for spaces where the combined conditions concerning the uniformity of tracer gas concentration, measurement of the exhaust gas concentration, effective mixed zone and/or fluctuation of ventilation are satisfied.ISO 12569:2017 provides three measurement methods using a tracer gas: concentration decay method, continuous dose method, and constant concentration method.NOTE Specific measurement conditions are given in Table 1.
