1.1 This terminology standard defines terms used in the description and procedures of analysis of particulate materials not ordinarily analyzed using test sieves. The terms relate directly to the equipment used in analysis, the physical forms of the materials to be analyzed, and selected descriptive data reduction and analysis formats.
1.2 Committee E29 on Powder and Spray Characterization believes that it is essential to include terms and definitions explicit to the scope, regardless of whether the terms appear in existing ASTM standards. Terms that are in common usage and appear in common-language dictionaries are generally not included, unless they have specific meanings different from the common-language definitions.
nonsieving methods; particle size analysis; particle size measurement; particle size; particles; particulate; powder; powder characterization; surface area
Much confusion exists in the powder industries regarding definitions of various terms relating to the characterization of powders, particularly the terms relating to particle size. This terminology standard will attempt to reduce this confusion by defining terms in such a way that the powder industries' jargon can be understood by all involved stakeholders.
