ASTM E454-12(2016)

Standard Specification for Industrial Perforated Plate and Screens (Square Opening Series)

ABSTRACT
This specification covers the various sizes of square opening perforated plates and screens for general industrial uses, including the separating or grading of materials according to designated nominal particle size, and lists standards for openings punched with various bar sizes and thicknesses of plate for various grades of service. This specification does not apply to perforated plate or screens with round, hexagon, slotted, or other shaped openings.
SCOPE
1.1 This specification covers the sizes of square 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 0.127 (1/8 ) in. (3.35 mm) 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 Annex A3.  
1.2 This specification does not apply to perforated plate or screens with round, hexagon, slotted, or other shaped openings.  
1.3 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 standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

This standard is issued under the fixed designation E454; 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 standard, 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

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.

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 standard, it is recommended that he consult his perforated plate supplier on the availability
of an acceptable alternative specification.
