Indoor air - Determination of local mean ages of air in buildings for characterizing ventilation conditions algolia-search-ignore instrumental techniques include the continuous1 Scope This part of ISO 16000 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 a) checking whether the building ventilation requirements are met, b) estimating the adequacy of ventilation in buildings with
