Designation:D819318Standard Test Method forTotal Oil and Grease(TOG)and Total PetroleumHydrocarbon(TPH)in Water and Wastewater with SolventExtraction Using Non-Dispersive Mid-IR TransmissionSpectroscopy1This standard is issued under the fixed designation D8193;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 covers the determination of total oiland grease(TOG)that can be extracted from water or waste-water samples by cyclohexane and measured by non-dispersiveIR spectroscopy from 13701380 cm-1.Treating the extractwith Florisil2to remove polar substances prior to the IRmeasurement enables determination of the total petroleum(TPH).1.2 This method also considers the volatile fraction ofpetroleum hydrocarbons which is lost by gravimetric methodsthat require solvent evaporation prior to weighing,as well asby solventless IR methods that require drying of the employedsolid phase material prior to measurement.Similarly,a morecomplete fraction of extracted petroleum hydrocarbon is ac-cessible by this method as compared to GC methods that use atime window for quantification,as petroleum hydrocarbonseluting outside these windows are also quantified.1.3 This method defines total oil and grease in water asmaterial that can be extracted with cyclohexane and measuredby IR absorption in the region of 13701380 cm-1(7.257.3m).Similarly,total petroleum hydrocarbon in water is definedas material that can be extracted with cyclohexane,remains inthe extract after filtration over Florisil and is measured by IRabsorption in the region of 13701380 cm-1(7.257.3 m).Theconcentration of total grease is defined as the differencebetween the total oil and grease and total petroleum hydrocar-bon concentrations.1.4 This method covers the range of 0.5 to 1000 mg/L fortotal oil and grease as well as for total petroleum hydrocarbonsand has a method detection limit(MDL)of 0.5 mg/L.Therange and method detection limit may be extended to higher orlower concentrations by adjusting the water or solvent volumeused in the liquid-liquid extraction.1.5 The values stated in SI units are to be regarded asstandard.No other units of measurement are included in thisstandard.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,health,and environmental practices and deter-mine the applicability of regulatory limitations prior to use.1.7 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:3D1129 Terminology Relating to WaterD1141 Practice for the Preparation of Substitute OceanWaterD1193 Specification for Reagent WaterD2777 Practice for Determination of Precision and Bias ofApplicable Test Methods of Committee D19 on WaterD3370 Practices for Sampling Water from Closed ConduitsD5847 Practice for Writing Quality Control Specificationsfor Standard Test Methods for Water AnalysisD7678 Test Method for Total Oil and Grease(TOG)andTotal Petroleum Hydrocarbons(TPH)in Water and Waste-water with Solvent Extraction using Mid-IR Laser Spec-troscopyE168 Practices for General Techniques of Infrared Quanti-tative Analysis1This test method is under the jurisdiction of ASTM Committee D19 on Waterand is the direct responsibility of Subcommittee D19.06 on Methods forAnalysis forOrganic Substances in Water.Current edition approved Dec.15,2018.Published January 2019.DOI:10.1520/D8193-18.2Florisil is a trademark by U.S.Silica Company,Frederick,MD.3For 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 2.2 ISO Standards:4ISO 9377-2 Determination of Hydrocarbon Oil Index2.3 Code of Federal Regulations(CFR)Publications:540 CFR Part 136 Guidelines Establishing Test Proceduresfor the Analysis of Pollutants49 CFR Part 172 Hazardous Materials Table,SpecialProvisions,Hazardous Materials Communications,
