Designation:F72617Standard Test Method forSorbent Performance of Adsorbents for use on Crude Oiland Related Spills1This standard is issued under the fixed designation F726;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.Scope1.1 This test method covers laboratory tests that describe theperformance of adsorbents in removing crude oils,nonemulsi-fied oils and other floating,immiscible liquids from the surfaceof water.1.2 The values stated in SI units are to be regarded asstandard.No other units of measurement are included in thisstandard.1.3 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.Specific precautionary statements are given in 8.3.1.1.4 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:2D2859 Test Method for Ignition Characteristics of FinishedTextile Floor Covering MaterialsF716 Test Methods for Sorbent Performance of Absorbents2.2 Federal Standard:Fed.Std.No.141a Paint,Varnish,Lacquer and RelatedMaterials,Methods of Inspection,Sampling and Testing32.3 Military Specification:MIL-I-631DInsulation,Electric,SyntheticResinComposition,Nonrigid33.Terminology3.1 General Terminology:3.1.1 gellanta material such as a colloidal network orother aggregate network that pervades and holds a liquid in ahighly viscous fragile structure.Many gels may rapidly liquifywith added heat or ionic/polar addition.These materials aresoluble/flowable in excess liquid.3.1.2 sorbentan insoluble material or mixture of materialsused to recover liquids through the mechanisms of absorptionor adsorption,or both.3.1.3 thickenera material(usually of higher molecularweight)that is soluble in excess liquid.These materials gofrom dry to gummy(viscoelastic)to flowable and then soluble.The final viscosity depends only on the liquid to solid ratio.3.1.4 universal sorbentan insoluble material or mixture ofmaterials that will sorb both hydrophobic and hydrophilicliquid spills.3.2 Definitions:3.2.1 absorbenta material that picks up and retains aliquid distributed throughout its molecular structure causingthe solid to swell(50%or more).The absorbent is at least70%insoluble in excess fluid.3.2.2 adsorbentan insoluble material that is coated by aliquid on its surface including pores and capillaries without thesolid swelling more than 50%in excess liquid.3.2.3 adsorbent cubage factor“C”this is the ratio ofsorbent volume used to the liquid volume sorbed.3.2.4 cubagedefines cubic content,volume,or displace-ment.3.3 Definitions of Terms Specific to This Standard:3.3.1 This test method does not apply to belt,rope,or weirtype skimming devices.3.3.2 oila substantially water immiscible organic liquidthat will float on water(density less than 1 g/cm3),typicallywith surface tension less than 40 103N/m.1This test method is under the jurisdiction of ASTM Committee F20 onHazardous Substances and Oil Spill Response and is the direct responsibility ofSubcommittee F20.22 on Mitigation Actions.Current edition approved Nov.1,2017.Published December 2017.Originallyapproved in 1981.Last previous edition approved in 2012 as F726 12.DOI:10.1520/F0726-17.2For 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.3Available from DLA Document Services,Building 4/D,700 Robbins Ave.,Philadelphia,PA 19111-5094,http:/quicksearch.dla.mil.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 3.3.3 Type I adsorbent(roll,film,sheet,pad,blanket,web)a material with length and width much greater thanthickness and which has both linear form and strength suffi-cient to be handled either saturated or unsaturated.3.3.4 Type II adsorbent(loose)an unconsolidated,particu-late material without
