Designation:E1115Standard Specification forWoven Wire Test Sieve Cloth and Test Sieves1This standard is issued under the fixed designation E11;the number immediately following the designation indicates the year of originaladoption or,in the case of revision,the year of last revision.Anumber in parentheses indicates the year of last reapproval.Asuperscriptepsilon()indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the U.S.Department of Defense.1.Scope*1.1 This document specifies the technical requirements for;the woven wire test sieve cloth(sieve cloth)used in test sieves,the construction of test sieves,standard and non-standard testsieve frame sizes,and test procedures used to inspect sievecloth and the test sieves.This specification applies to test sievesmanufactured with sieve cloth having a nominal aperture sizeranging from 125 millimetres(mm)down to 20 micrometres(m).1.2 Additional reference information can be found in Speci-fications E161,E323,E2016,and in Test Methods C430 andE2427.1.3 The values stated in SI units shall be consideredstandard for the dimensions of the sieve cloth openings and thewire diameters used in the sieve cloth.The values stated ininch-pound units shall be considered standard with regard tothe sieve frames,pans,and covers.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 standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.Referenced Documents2.1 ASTM Standards:2C430 Test Method for Fineness of Hydraulic Cement by the45-m(No.325)SieveE161 Specification for Precision Electroformed SievesE323 Specification for Perforated-Plate Sieves for TestingPurposesE1638 Terminology Relating to Sieves,Sieving Methods,and Screening MediaE2016 Specification for Industrial Woven Wire ClothE2427 Test Method for Acceptance by Performance Testingfor Sieves2.2 Federal Standard:Fed.Std.No.123 Marking for Shipment(Civil Agencies)32.3 Military Standard:MIL-STD-129 Marking for Shipment and Storage32.4 ISO Standard:ISO 3310-1 Test SievesTechnical Requirements and Test-ing Part 1:Test Sieves of Metal Wire Cloth43.Terminology3.1 DefinitionsAdditional terms can be found in Termi-nology E1638.3.1.1 aperturethe dimension defining an opening in ascreening surface.3.1.2 backing clotha wire mesh support layer used di-rectly under the sieve cloth with an opening coarser than thesieve designation.3.1.3 crimpthe corrugation in the warp and shute wire,orboth.The crimp in the wires is formed either during theweaving process,or with a crimping machine prior to weaving.If formed during the weaving process,the tension existingbetween the warp and shute wires fundamentally determinesthe respective amount or depth of crimp,which locks the wiresin place,and in part establishes the firmness of the sieve cloth.3.1.4 firmnessa subjective term referring to the planarrigidity of sieve cloth(as a roll good,not mounted in a testsieve frame),established by the tensile strength of the material,the relationship of the mesh to wire diameters,the type ofweave,and amount of crimp in the wires.The absence offirmness in sieve cloth is termed sleaziness.3.1.5 matched test sievea test sieve that reproduces theperformance results of another test sieve within user definedlimits for a designated material(for information only and maynot be in compliance with this specification).1This specification is under the jurisdiction ofASTM Committee E29 on Particleand Spray Characterization and is the direct responsibility of Subcommittee E29.01on Sieves,Sieving Methods,and Screening Media.Current edition approved March 15,2015.Published March 2015.Originallyapproved in 1925.Last previous edition approved in 2013 as E11 13.DOI:10.1520/E0011-15.2For referenced ASTM standards,visit the ASTM website,www.astm.org,orcontact ASTM Customer Service at serviceastm.org.For Annual Book of ASTMStandards volume information,refer to the standards Document Summary page onthe ASTM website.3Available from Standardization Documents Order Desk,DODSSP,Bldg.4,SectionD,700RobbinsAve.,Philadelphia,PA19111-5098,http:/www.dodssp.daps.mil.4Available from American National Standards Institute(ANSI),25 W.43rd St.,4th Floor,New York,NY 10036,http:/www.ansi.org.*A Summary of Changes section appears at the end of this standardCopyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 3.1.6 meshthe number of wires or openings per linear inch(25.4 mm)counted from the center of any wire to a pointexactly 1 in.(25.4 mm)distant,including the fractionaldistance between either thereof.3.1.7 plain weavesieve cloth in which the warp wires andshute wires pass over one and under one in both directions.3.1.8 shute wiresthe wires running the short way of,oracross the cloth as woven(also referred to
