ASTM E674-12(2021)

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.
Designation:E674 −12 (Reapproved 2021)
Standard Specification for
Industrial Perforated Plate and Screens (Round Opening
Series)
This standard is issued under the fixed designation E674; 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
Industrial perforated plate can be produced in many thousands of combinations of size and shape
of opening, bar size, thickness of material, and type of metal. Such variety is often confusing and, to
the vast majority of perforated plate users, unnecessary, since each usually requires only a very few
specifications.
The purpose of this specification is to simplify this problem by a condensed table of recommended
specifications covering a wide range of openings in which industrial perforated plate is made, with
several recommended bar sizes and thicknesses of plate for each opening, for use in various grades of
service.
By making selections from this specification, the user will be guided to specifications that are being
regularly produced, thus avoiding inadvertent selection of specifications that, because of little or no
demand,areunobtainable,exceptonspecialorder(usuallyquiteexpensiveunlessthequantityordered
