Standard Terminology Relating to Nonsieving Methods of Powder Characterization
SIGNIFICANCE AND USE
3.1 Interpretation and use of data generated by particle characterization methods is highly dependent on the definitions of terms describing that data. It is extremely important that those terms be defined in precisely the same way both when comparing data from different characterization techniques and even when correlating data from the same technique.
3.2 It is likewise important that users of particle characterization methods and the data generated therefrom understand the principles of the methods, so that differences and similarities in the data can be interpreted in relation to those principles. That understanding can help to avoid disagreements when data from different characterization methods are compared.
3.3 The definitions contained in this terminology will aid in the interpretation of particle characterization data with respect to the method(s) used to produce that data.
SCOPE
1.1 This terminology covers the definitions of 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 Particle and Spray Characterization believes that it is essential to include terms and definitions explicit to the committee’s 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 in the context of particle characterization different from the common-language definitions.
1.3 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

INTRODUCTION
Particle size distribution, surface area, and other forms of particle analysis have been commonly
adopted methods of verifying compliance with desired particle specifications for some time. Greater
emphasis is now being placed on inter- and intralaboratory correlation of all particle measurement
systems.
To ensure a better understanding of the comparison of testing results from particle measurement
systems, terminology relating to the measurements must be clearly defined and documented so that
both the recipient and generator of the data are in full agreement as to the meaning of the data. Every
effort has been made here to ensure accuracy, precision, and clarity for the terms included in this
terminology document. For Committee E29, this is an ongoing process with new terms being
developed and defined for future inclusion. Suggestions and comments for additions, corrections, and
revisions are welcomed.

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
