(Specification)Standard Specification for Industrial Perforated Plate and Screens (Round Opening Series)
Standard Specification for Industrial Perforated Plate and Screens (Round Opening Series)
SCOPE
1.1 This specification covers the sizes of round opening perforated plate and screens for general industrial uses, including the separating or grading of materials according to designated nominal particle size, and lists standards for openings from 5 in. (125 mm) to 0.020 in. (500 [mu]m) punched with bar sizes and thicknesses of plate for various grades of service. Methods of checking industrial perforated plate and screens are included as information in the Appendix.
1.2 This specification does not apply to perforated plate or screens with square, hexagon, slotted, or other shaped openings.
1.3 The values stated in inch-pound units are to be regarded as the standard.

Designation: E 674 – 80 (Reapproved 1996) An American National Standard
Standard Specification for
Industrial Perforated Plate and Screens (Round Opening
Series)
This standard is issued under the fixed designation E 674; 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.
This standard has been approved for use by agencies of the Department of Defense.
e NOTE—Keywords were added editorially in March 1996.
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, are unobtainable, except on special order (usually quite expensive unless the quantity ordered
is sufficient to justify the cost of special tooling).
If a user has a specific application for industrial perforated plate that can not be solved by a selection
from this specification, it is recommended that he consult his perforated plate supplier on the
availability of an acceptable alternative specification.
