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

ABSTRACT
This specification covers the various sizes of round 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 plates or screens with square, hexagon, slotted, or other shaped openings.
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 μm) 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 Appendix X3.  
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 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.

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
is sufficient to justify the cost of special tooling).

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.
Designation: E674 − 12 E674 − 12 (Reapproved 2016)
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, 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.
1. Scope*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 μm) 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 Appendix X3.
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 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.

3. Terminology
3.1 Definitions—For general terms related to sieves, sieving methods, and screening media, see Terminology E1638.
3.2 Definitions of Terms Specific to This Standard:
3.2.1 aperture, n—the opening in a screening or sieving medium.
3.2.2 bar, n—the metal between perforations.
3.2.3 blank, n—unperforated area located other than along the perimeter of a plate.
3.2.4 break-out, n—term applied to the action that occurs ahead of the punch in its going through the plate.
Available from Standardization Documents Order Desk, DODSSP, Bldg. 4, Section D, 700 Robbins Ave., Philadelphia, PA 19111-5098, http://dodssp.daps.dla.mil.
3.2.4.1 Discussion—
The fracturing of the material results in a tapered hole with the small dimensions on the punch side.
3.2.5 centers, n—dimensional sum of one perforation and one bar or the dimensional distance from the center of one perforation
to the center of an adjacent perforation.
3.2.6 die side, n—surface of the plate that was against the die during the punching operation.
3.2.7 finished end pattern, n—condition that occurs with some specifications of staggered pattern perforations as a result of tool
design in which the pattern is completed on both ends of the plate (Fig. 1).
3.2.8 gage (alsogauge)gauge), , n—a number designating a specific thickness of metal sheet tabulated in a standardized series,
each of which represents a decimal fraction of an inch.
3.2.9 margin orborder, , n—unperforated area located along the perimeter of a plate.
3.2.10 percent open area, n—the ratio of the total area of the apertures to the total area expressed in percentage.
3.2.11 perforated pattern, n—the patterns that the perforations are arranged in, usually in a staggered pattern with midpoints
nominally at the vertices of isosceles triangles or square patterns arranged in line with their midpoints nominally at the vertices
of squares.
3.2.12 screen, n—(1) surface provided with apertures of uniform size and shape; (2) another term used interchangeably for
woven wire cloth; (3) machine provided with one or more screen surfaces.
3.2.13 screening, v—process of separating a mixture of different sizes by means of one or more screen surfaces.
3.2.14 smooth side or punch side, n—surface of the plate that was uppermost during the punching operation and through which
the punch entered the plate.
3.2.15 unfinished end pattern, n—condition that occurs with some specifications of staggered pattern perforations as a result of
tool design.
3.2.15.1 Discussion—
On one end of the plate, the pattern will appear to be incomplete as a result of unperforated holes in the even numbered rows, while
on the other end of the same plate, the pattern will appear to be incomplete because of unperforated holes in the odd numbered
rows (Fig. 2).

E674 − 12 (2016)
FIG. 2 Unfinished End Pattern
4. Standard Specifications
4.1 Standard specifications for industrial perforated plate and screens are listed in Table 1.
4.2 Openings—The series of standard openings listed in Table 1 include those of the USA Standard Sieve Series, Specification
E323, and those of the ISO apertures for industrial plate screens, ISO 2194, with the addition of those openings in common usage.
4.3 Relationship of Grades—The purpose of the several grades is to provide combinations of opening and bar size for various
types of service, from medium-light to heavy. Since it is possible to vary the bar size independently from the plate thickness, each
of the service grades lists up to three combinations of bar and gage for each opening. The entire standard series has been designed
for a logical relationship of bar size to opening in each grade and between grades with the capability of also being able to vary
the plate thickness.
