Designation:E242713Standard Test Method forAcceptance by Performance Testing for Sieves1This standard is issued under the fixed designation E2427;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope1.1 This test method is a performance test for acceptance ofsieves.1.2 This test method compares the performance of a sieveagainst an inspection or calibration sieve using a knownquantity of reference material such that the long-term stabilityof sieves can be measured.1.3 This is a test method for checking the accuracy andlong-term reliability of test sieves.Since it is not possible toadjust the measuring capability of a test sieve,the test methodis designed to offer a verification procedure based on sievingperformance by comparison to a standard reference.This testmethod is not proposed as an alternative to the inspectionmethods in accordance with Specification E11 or the proce-dures in MNL 32.1.4 UnitsThe values stated in SI units are to be regardedas standard.All other values given are for information only.1.5This test method 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:2E11 Specification for Woven Wire Test Sieve Cloth and TestSievesE177 Practice for Use of the Terms Precision and Bias inASTM Test MethodsE691 Practice for Conducting an Interlaboratory Study toDetermine the Precision of a Test MethodE1638 Terminology Relating to Sieves,Sieving Methods,and Screening MediaMNL 32 Manual on Test Sieving Methods Guidelines forEstablishing Sieve Analysis Procedures3.Terminology3.1 Definitions of terms relating to sieve analysis can befound in Terminology E1638.3.2 calibration test sieve,na test sieve manufacturedusing sieve cloth which has been inspected after being mountedin the sieve frame,and that meets the requirements of Table 1of Specification E11 in part based on the standard deviation ofthe required number of sample openings in the test sieve(Column 11)not exceeding the maximum allowable for aconfidence level of 99.73%(Column 12).E113.3 endpoint,npoint at which no material falls through thesieve concluding the sieving,taking into account sampledegradation.3.4 inspection test sieve,natest sieve manufactured usingsieve cloth which has been inspected after being mounted inthe sieve frame,and that meets the requirements of Table 1 ofSpecification E11 in part based on the standard deviation of therequired number of sample openings in the test sieve(Col-umn 9)not exceeding the maximum allowable for a confidencelevel of 99%(Column 10).E113.5 percent retained,nmass fraction percentage of mate-rial that is left upon or retained by the sieve after the test hasbeen performed.3.6 sieve,nan apparatus consisting of a medium withregularly spaced apertures of uniform size,mounted in asuitable frame or holder,for use in separating material accord-ing to size.3.7 sieve shaker,nthe mechanical device or method usedto shake the sieves,excluding hand sieving.4.Significance and Use4.1 This test method may be used by producers,users,andgeneral interest parties for research and development or pro-duction quality control work,and is useful for the comparisonof sieves.4.2 Because the reference materials particle size distribu-tion will affect the acceptance tolerance,the user shoulddetermine an acceptance tolerance based on their specificreference material.1This test method is under the jurisdiction of ASTM Committee E29 on Particleand Spray Characterization and is the direct responsibility of Subcommittee E29.01on Sieves,Sieving Methods,and Screening Media.Current edition approved Nov.1,2013.Published November 2013.Originallyapproved in 2005.Last previous edition approved in 2011 as E2427 11.DOI:10.1520/E2427-13.2For 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.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 5.Interferences5.1 The long-term use of sieves can compromise the reli-ability of test results.Depending on the type of materials beingmeasured,wear can occur on the diameter of the wires causingopening sizes to change and measuring capability to drift.5.2 The specific particle size distribution of the referencematerial will affect the acceptance tolerance.Therefore eachreference material shall be developed based on a desiredparticle size distribution.5.3 Care should be taken with the use o
