Designation:D810617Standard Test Methods forDetermining the Oil Sorption Capacity of Organophilic Clay1This standard is issued under the fixed designation D8106;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 standard covers two test methods(Method A forgranular material,Method B for powdered material)that can beused as an index test for the evaluation of the oil sorptioncapacity of a representative sample of organophilic clay.Thetest method is not intended to be a performance test and the oilspecified in the test methods may yield different results thanother non-aqueous phase liquids(for example,coal tar,creosote,crude oil)encountered in the field.Method A shouldonly be used on granular organophilic clay;otherwise finerparticles may pass through the test sieve.1.2 All observed and calculated values shall conform to theguidelines for significant digits and rounding established inPractice D6026.1.2.1 The procedures used to specify how data are collected/recorded or 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 the reported data to becommensurate with these considerations.It is beyond the scopeof this standard to consider significant digits used in analysismethods for engineering design.1.3 UnitsThe values stated in SI units are to be regardedas the primary units for the standard.For information only,non-SI units of measurement are also included in this standardto describe some equipment(bucket,sieve).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,health and environmental practices and deter-mine the applicability of regulatory limitations prior to use.1.5 This international standard was developed in accor-dance with internationally recognized principles on standard-ization established in the Decision on Principles for theDevelopment of International Standards,Guides and Recom-mendations issued by the World Trade Organization TechnicalBarriers to Trade(TBT)Committee.2.Referenced Documents2.1 ASTM Standards:2D653 Terminology Relating to Soil,Rock,and ContainedFluidsD3740 Practice for Minimum Requirements for AgenciesEngaged in Testing and/or Inspection of Soil and Rock asUsed in Engineering Design and ConstructionD4753 Guide for Evaluating,Selecting,and Specifying Bal-ances and Standard Masses for Use in Soil,Rock,andConstruction Materials TestingD6026 Practice for Using Significant Digits in GeotechnicalDataD6913 Test Methods for Particle-Size Distribution(Grada-tion)of Soils Using Sieve AnalysisE11 Specification for Woven Wire Test Sieve Cloth and TestSieves3.Terminology3.1 Definitions:3.1.1 For definitions of common technical terms in thisstandard,refer to Terminology D653.3.2 Definitions of Terms Specific to This Standard:3.2.1 granular organophilic clay,na manufactured oleo-philic material consisting of base clay to which an organiccompound has been chemically bonded to the clay surface withat least 95%material,by dry mass,retained on a 210 m(No.70)sieve in accordance with D6913.3.2.2 powdered organophilic clay,na manufactured oleo-philic material consisting of base clay to which an organiccompound has been chemically bonded to the clay surface withat least 65%material,by dry mass,passing a 75 m(No.200)sieve.1This test method is under the jurisdiction ofASTM Committee D18 on Soil andRock and is the direct responsibility of Subcommittee D18.21.07 on Groundwaterand Vadose Zone Remediation Technologies.Current edition approved July 15,2017.Published August 2017.DOI:10.1520/D8106-172For 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 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 4.Summary of Test Method4.1 In MethodA,a granular organophilic clay is mixed witha specified classification of commercial oil and then gravitydrained for a
