Standard Terminology Relating to Sieve Analysis
SCOPE
1.1 This terminology defines terms used in the description and procedure of analysis of the size of particulate materials through sieve analysis with standard testing sieves. The terms relate directly to the equipment used in the analysis, the physical forms of the material to be sieved may take on before, during, or after analysis, and selected descriptive data reduction and analysis formats.
1.2 Committee E-29 on Particle Size Measurement 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 Sieve Analysis
This standard is issued under the fixed designation E 1638; 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 (e) indicates an editorial change since the last revision or reapproval.
INTRODUCTION
Particle size distribution analysis through the use of standard testing sieves has been a commonly
adopted method of verifying compliance with desired process particle specifications for many
decades.As an adjunct to that function, greater emphasis is being placed on inter- and intralaboratory
correlation of all particle measurement systems, testing sieves included.
To ensure a better understanding of the comparison of testing results from sieve analysis-based
particle measurement systems, terminology common to the process must be documented and defined
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 to ensure accuracy, precision, and clarity for the terms included in this
terminology. For Committee E-29, this is an on-going process with new terms being developed for
future inclusion. Suggestions and comments for additions, corrections, and revisions are welcomed.
