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 the Appendix.
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 e standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.
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.

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
