Designation:D678416Standard Test Method forElemental,Oxidized,Particle-Bound and Total Mercury inFlue Gas Generated from Coal-Fired Stationary Sources(Ontario Hydro Method)1This standard is issued under the fixed designation D6784;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 applies to the determination ofelemental,oxidized,particle-bound,and total mercury emis-sions from coal-fired stationary sources.1.2 This test method is applicable to elemental,oxidized,particle-bound,and total mercury concentrations ranging fromapproximately 0.5 to 100 g/Nm3.1.3 This test method describes equipment and proceduresfor obtaining samples from effluent ducts and stacks,equip-ment and procedures for laboratory analysis,and proceduresfor calculating results.1.4 This test method is applicable for sampling elemental,oxidized,and particle-bound mercury in flue gases of coal-firedstationary sources.It may not be suitable at all measurementlocations,particularly those with high particulate loadings,asexplained in Section 16.1.5 Method applicability is limited to flue gas streamtemperatures within the thermal stability range of the samplingprobe and filter components.1.6 The values stated in SI units are to be regarded as thestandard.The values in parentheses are for information only.1.7 This standard requires users to be familiar with EPAstack-gas sampling procedures as stated in EPA Methods 14,Method 5,and Method 17.1.8 The method requires a high level of experience andquality control both in the field testing and analytical proce-dures in order to obtain high quality data.1.9 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 and health practices and determine the applica-bility of regulatory limitations prior to use.2.Referenced Documents2.1 ASTM Standards:2D1193 Specification for Reagent WaterD1356 Terminology Relating to Sampling and Analysis ofAtmospheresD3154 Test Method for Average Velocity in a Duct(PitotTube Method)D3685/D3685M Test Methods for Sampling and Determina-tion of Particulate Matter in Stack GasesD3796 Practice for Calibration of Type S Pitot TubesD4840 Guide for Sample Chain-of-Custody ProceduresD7036 Practice for Competence of Air Emission TestingBodiesE2251 Specification for Liquid-in-Glass ASTM Thermom-eters with Low-Hazard Precision Liquids2.2 Other Standards:3EPAMethod 1 Sample and Velocity Traverses for StationarySourcesEPA Method 2 Determination of Stack Gas Velocity andVolumetric Flow Rate(Type S Pitot Tube)EPA Method 3 Gas Analysis for the Determination of DryMolecular WeightEPA Method 4 Determination of Moisture Content in StackGasesEPA Method 5 Determination of Particulate Emissions fromStationary SourcesEPA Method 12 Determination of Inorganic Lead Emissionsfrom Stationary SourcesEPA Method 17 Determination of Particulate Emissionsfrom Stationary Sources(In-Stack Filtration Method)EPA Method 29 Determination of Metals Emissions fromStationary Sources1This test method is under the jurisdiction of ASTM Committee D22 on AirQuality and is the direct responsibility of Subcommittee D22.03 on AmbientAtmospheres and Source Emissions.Current edition approved March 1,2016.Published June 2016.Originallyapproved in 2002.Last previous edition approved in 2008 as D6784 02(2008).DOI:10.1520/D6784-16.2For 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.3EPA Methods 1 29 available from the U.S.Environmental ProtectionAgencys Emission Measurement Technical Information Center or Code of FederalRegulations(40 CFR Part 60,Appendix A),Method 101A in 40 CFR Part 61,Appendix B,Method 301 in 40 CFR 63 Appendix A40 CFR Part 61,Appendix B.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 EPA Method 101A Determination of Particle-Bound andGaseous Mercury Emissions from Sewage Sludge Incin-eratorsEPA Method 301 Field Validation of Pollutant MeasurementMethods from Various Waste MediaEPA SW 846 7470A Mercury in Liquid WasteManualCold Vapor TechniqueEPA Water and Waste 600/4-79-020 Methods for ChemicalAnalysis of Water and Wastes3.Terminology3.1 Definitions other than those given below in 3.2 and 3.3are listed in Terminology D1356.3.2 Definitions of Terms Specific to This Standard:3.2.1 elemental mercurymercury in its zero oxidationstate,Hg0.3.2.2 elemental mercury catchmercury collected in theacidified hydrogen peroxide(HNO3H2O2)and potassiumpermanganate(H2SO4KMnO4)impinger solutions empl
