标准摘要
[中文适用范围]： 本文件建立了使用示踪气体获取建筑空间（被认为是单个区域）中的通风率或特定气流率的方法。 本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。 本文件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：具体测量条件见表1。 [外文原描述]： 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.
