英文名称：Indoor air — Part 8: Determination of local mean ages of air in buildings for characterizing ventilation conditions

发布日期：2007-06

标准范围

This part of ISO 16000 describes the use of single tracer gas for determining the local mean age of air as anindicator of ventilation conditions in a building. The procedures include concentration decay andhomogeneous constant emission.The described methods are intended for air quality studies and can be used fora) checking whether the building ventilation requirements are met,b) estimating the adequacy of ventilation in buildings with indoor air quality problems, andc) 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 thestate of mixing of air between zones. The prevailing ventilation conditions need not be disturbed by themeasurement.This part of ISO 16000 does not address the details of the analytical methods for tracer gases. The availabilityof such analysis services should be checked before planning actual field measurements.
