1、Designation: E 454 80 (Reapproved 2004)Standard Specification forIndustrial Perforated Plate and Screens (Square OpeningSeries)1This standard is issued under the fixed designation E 454; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revisi
2、on, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript 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.INTRODUCTIONIndustrial perforate
3、d plate can be produced in many thousands of combinations of size and shapeof opening, bar size, thickness of material, and type of metal. Such variety is often confusing and, tothe vast majority of perforated plate users, unnecessary, since each usually requires only a very fewspecifications.The pu
4、rpose of this specification is to simplify this problem by a condensed table of recommendedspecifications covering a wide range of openings in which industrial perforated plate is made, withseveral recommended bar sizes and thicknesses of plate for each opening, for use in various grades ofservice.B
5、y making selections from this standard, the user will be guided to specifications that are beingregularly produced, thus avoiding inadvertent selection of specifications that, because of little or nodemand, are unobtainable, except on special order (usually quite expensive unless the quantity ordere

7、cation.1. Scope1.1 This specification covers the sizes of square openingperforated plate and screens for general industrial uses, includ-ing the separating or grading of materials according to desig-nated nominal particle size, and lists standards for openingsfrom 5 in. (125 mm) to 0.127 (18 ) in. (
8、3.35 mm) punched withbar sizes and thicknesses of plate for various grades of service.Methods of checking industrial perforated plate and screens areincluded as information in the Appendix.1.2 This specification does not apply to perforated plate orscreens with round, hexagon, slotted, or other shap

The values given in parentheses are forinformation only.1.4 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the user of this stand

15、Std-129 Marking for Shipment and Storage43. Standard Specifications3.1 Standard specifications for industrial perforated plateand screens are listed in Table 1.3.2 OpeningsThe series of standard openings listed inTable 1 include those of the USA Standard Sieve Series,Specification E 323, and those o
16、f the ISO apertures forindustrial plate screens, ISO 21941972, with the addition ofthose openings in common usage.3.3 Relationship of GradesThe purpose of the severalgrades is to provide combinations of opening and bar size forvarious types of service, from medium-light to heavy. Since itis possible
17、 to vary the bar size independently from the platethickness, each of the service grades lists up to three combi-nations of bar and gage for each opening. The entire standardseries has been designed for a logical relationship of bar size toopening in each grade and between grades with the capabilityo
18、f also being able to vary the plate thickness.TABLE 1 USA Standard Specifications for Industrial Perforated Plate and Screens (Square Opening Series)(U.S. Customary Units)Perforated Opening Medium Light Medium Medium Heavy HeavyStandard(metric),mmUSA In-dustrialStandard,in.Open-ing, in.Bar,in.Gage-S
