ISO 4225:2020 Scope
This document specifies terms and definitions that are related to air quality (see 3.1.1.1). These are either general terms or are used in connection with the sampling (see 3.3.3.1) and measurement of gases, vapours (see 3.1.5.8) and airborne particles (see 3.2.2.1) 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.
This document is applicable to all International Standards, ISO Technical Reports, ISO Technical Specifications, and ISO Guides related to air quality.
