Standard Terminology Relating to Sieves, Sieving Methods, and Screening Media
SCOPE
1.1 This terminology includes all those terms used in all of the standards under the jurisdiction of Subcommittee E29.01. Terms are defined that are related to the manufacture of standard test sieves and screening media, as well as terms related to the methods, analysis, procedures, and equipment for sizing and separating particles.
1.2 Committee E29 on Particle and Spray Characterization feels 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.
1.3 Units—The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
1.4 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.

Standard Terminology

Relating to Sieves, Sieving Methods, and Screening Media
This standard is issued under the fixed designation E1638; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (´) indicates an editorial change since the last revision or reapproval.
INTRODUCTION
Particle size analysis through the use of standard test sieves, and particle separation through the use
of screening media, are commonly adopted methods of achieving desired process specifications
related to particles. To ensure a better understanding of sizing and separation systems and processes
and to ensure appropriate comparison of data, terminology common to the processes must be
documented and defined.
For Subcommittee E29.01 on Sieves, Sieving Methods, and Screening Media, this is an ongoing
process of developing new related terms. Every effort has been made to ensure accuracy, precision,
and clarity for the terms included. Suggestions and comments for additions, corrections, and revisions
are welcomed.
