This document specifies terms and definitions that are related to air quality (see 188.8.131.52). These are either general terms or are used in connection with the sampling (see 184.108.40.206) and measurement of gases, vapours (see 220.127.116.11) and airborne particles (see 18.104.22.168) for the determination of air quality.
The terms included are those that have been identified as being fundamental because their definition is necessary to avoid ambiguity and ensure consistency of use.
An alphabetical index of the terms is provided in Annex A.
