Air quality. General aspects. Vocabulary1 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

— by analogy to press printing from printing surfaces produced by direct imaging

— hazards related to conveying devices other than those defined in 3
