Designation:D836120Standard Test Method forTotal Organic Carbon in Water by Two Stage Wet ChemicalCatalyzed Hydroxyl Radical Oxidation with Infra-RedDetection of Resulting Carbon Dioxide1This standard is issued under the fixed designation D8361;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 catalyzed hydroxyl radicaloxidation system for the in-stream,online(Guide D5173)orlaboratory analysis of total organic carbon,total carbon andtotal inorganic carbon in drinking water,wastewater,industrialprocess water,and effluent water.It is applicable to bothdissolved and suspended materials.Suspended materials andparticulates up to 2 mm in diameter can be analyzed.1.2 This test method allows for determination of TOC 1mg/L,TC 1 mg/L,and TIC 1 mg/L.The lower and upperworking ranges are restricted by instrument-dependent condi-tions(for example,sample volume,amount of each reactant)and can be adjusted for a wider range.1.3 This test method can be applied for the determination oftotal carbon(TC)and total inorganic carbon(TIC).Volatile orpurgeable organic carbon(VOC,POC)can be determinedseparately by this test method(see Annex A1).1.4 This test method allows the measurement of organic andinorganic carbon concentration samples,and samples contain-ing dissolved chlorides up to seawater chloride concentrations.1.5 The chemical oxidation process,applied in this testmethod,takes place at ambient pressure and temperature byusing hydroxyl radicals.The advantage of catalytic hydroxylradical oxidation is that it is free from seawater salinityinterference.1.6 The values stated in SI units are to be regarded asstandard.No other units of measurement are included in thisstandard.1.7 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.For specific hazard statements,see Section 9.1.8 ASTM International takes no position respecting thevalidity of any patent rights asserted in connection with anyitem mentioned in this standard.Users of this standard areexpressly advised that determination of the validity of any suchpatent rights,and the risk of infringement of such rights,areentirely their own responsibility.1.9 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:2D1129 Terminology Relating to WaterD1193 Specification for Reagent WaterD2777 Practice for Determination of Precision and Bias ofApplicable Test Methods of Committee D19 on WaterD3694 Practices for Preparation of Sample Containers andfor Preservation of Organic ConstituentsD4453 Practice for Handling of High Purity Water SamplesD5173 Guide for On-Line Monitoring of Total OrganicCarbon in Water by Oxidation and Detection of ResultingCarbon DioxideD5847 Practice for Writing Quality Control Specificationsfor Standard Test Methods for Water Analysis2.2 Other Standard:EN 1484 Water analysis guidelines for the determination oftotal organic carbon and dissolved organic carbon31This test method is under the jurisdiction of ASTM Committee D19 on Waterand is the direct responsibility of Subcommittee D19.03 on Sampling Water andWater-Formed Deposits,Analysis of Water for Power Generation and Process Use,On-Line Water Analysis,and Surveillance of Water.Current edition approved Dec.1,2020.Published December 2020.DOI:10.1520/D8361-20.2For 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.3Water Analysis Guidelines for the Determination of Total Organic Carbon andDissolved Organic Carbon,European Standard EN 1484,European Committee forStandardization,May 1997.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.3.Terminology3.1 DefinitionsFor definitions of terms used in this testmethod,refer to Terminology D1129.3.2 Definitions of Terms Speci
