Designation:D114017Standard Test Methods forDetermining the Amount of Material Finer than 75-m(No.200)Sieve in Soils by Washing1This standard is issued under the fixed designation D1140;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.This standard has been approved for use by agencies of the U.S.Department of Defense.1.Scope*1.1 These test methods cover the determination of theamount of material finer than a 75-m(No.200)sieve bywashing of material with a maximum particle size of 75 mm(3in.).1.2 The methods used in this standard rely on the use ofwater or a dispersant to separate and remove materials finerthan a 75-m(No.200)sieve.During these processes solublesubstances,such as salts and other minerals,may also beremoved.It is not within the scope of this standard todifferentiate between the removal of fine particles and solublesubstances.It is recommended that materials containing sig-nificant amounts of soluble substances be tested using othermethods of separation.1.3 Two methods for determining the amount of materialfiner than the 75-m(No.200)sieve are provided.The methodto be used shall be specified by the requesting authority.If nomethod is specified,the choice should be based upon theguidance given in 5.2,5.3,and 5.4.1.3.1 Method ATest specimen is dispersed by soaking inwater prior to wash sieving.1.3.2 Method BTest specimen is dispersed by soaking in adispersing solution prior to wash sieving.1.4 UnitsThe values stated in SI units are to be regardedas standard.Except the sieve designations are typically iden-tified using the“alternative”system in accordance with Speci-fication E11,such as 3 inch and No.200,instead of the“standard”of 75-mm and 75-m,respectively.Reporting oftest results in units other than SI shall not be regarded asnonconformance with this test method.The use of balances orscales recording pounds of mass(lbm)shall not be regarded asnonconformance with this standard.1.5 All observed and calculated values shall conform to theguidelines for significant digits and rounding established inPractice D6026,unless superseded by this test method.1.5.1 The procedures used to specify how data are collected/recorded and calculated in this standard are regarded as theindustry standard.In addition,they are representative of thesignificant digits that generally should be retained.The proce-dures used do not consider material variation,purpose forobtaining the data,special purpose studies,or any consider-ations for the users objectives;and it is common practice toincrease or reduce significant digits of reported data to becommensurate with these considerations.It is beyond the scopeof these test methods to consider significant digits used inanalysis methods for engineering design.1.6 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:2C702 Practice for Reducing Samples ofAggregate to TestingSizeD75 Practice for Sampling AggregatesD422 Test Method for Particle-Size Analysis of Soils(With-drawn 2016)3D653 Terminology Relating to Soil,Rock,and ContainedFluidsD1586 Test Method for Penetration Test(SPT)and Split-Barrel Sampling of SoilsD1587 Practice for Thin-Walled Tube Sampling of Fine-Grained Soils for Geotechnical PurposesD2216 Test Methods for Laboratory Determination of Water(Moisture)Content of Soil and Rock by Mass1These test methods are under the jurisdiction ofASTM Committee D18 on Soiland Rock and is the direct responsibility of Subcommittee D18.03 on Texture,Plasticity and Density Characteristics of Soils.Current edition approved Feb.1,2017.Published February 2017.Originallyapproved in 1950.Last previous edition approved in 2014 as D1140 14.DOI:10.1520/D1140-17.2For 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.3The last approved version of this historical standard is referenced onwww.astm.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 StatesThis international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for theDevelopment of International Standards,Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade(TBT)Committee.1 D2487 Practice for Classification of Soil
