1.1 In a broad sense, this terminology covers terminology associated with liquid particles dispersed in gas. The principal emphasis, however, is on particles produced by the process of atomization.
1.2 All terms, followed by their definitions, are arranged alphabetically. In addition, the terminology contains several tables wherein terms related to specific subjects are segregated and identified.
1.3 Within the broad scope, the following specific categories are included:
1.3.1 Terms pertaining to the structure and condition of individual particles or groups of particles as observed in nature.
1.3.2 Terms pertaining to the structure and condition of individual particles or groups of particles produced by an atomizing device.
1.3.3 Terms pertaining to atomizing devices according to the primary energy source responsible for spray development. (When more than one term is used for the same device or class of devices, the alternative term is followed by the preferred term.) Definitions of the devices may refer to their construction, operating principle, or distinctive spray characteristics. The atomizers, however, are not classified by their respective areas of application or end use. Moreover, the listed terms are generic and do not include brand names, trademarks, or proprietary designations.
1.3.4 Terms pertaining to statistical parameters involving particle measurement, particle size, and size distribution functions.
1.3.5 Terms pertaining to instruments and test procedures utilized in the characterization of liquid particles and sprays.
1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
