(Terminology)Standard Terminology Relating to Sieves, Sieving Methods, and Screening Media
Standard Terminology Relating to Sieves, Sieving Methods, and Screening Media
SIGNIFICANCE AND USE
This terminology contains terms used in the description and procedure of analysis of the size of particulate materials through sieve analysis with standard testing sieves and is applicable to the work of many ASTM technical committees. For a composite listing of published ASTM standards using standard testing sieves, refer to ASTM STP 447B.
While some of the terms appearing in this terminology may also be used in the description, procedure, and end products of production screening (either on a batch-fed or continuous basis), it is the intent of this terminology to present the definitions and usage of terms strictly in the context of sieve analysis using standard testing sieves.
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.

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.

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.
