1、Designation:D114014Standard 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
2、,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
3、 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 proce
4、sses 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 ot
5、hermethods 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
6、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 th
7、e“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 ma
8、ss(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values shall conform to theguidelines for significant digits and rounding established inPractice D6026,unless superseded by this test method.1.5.1 The procedures used to specify how data are collected/re
9、corded 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-ati
10、ons 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
11、 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
