Designation:D683111Standard Test Method forSampling and Determining Particulate Matter in Stack GasesUsing an In-Stack,Inertial Microbalance1This standard is issued under the fixed designation D6831;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 describes the procedures for determin-ing the mass concentration of particulate matter in gaseousstreams using an automated,in-stack test method.This method,an in-situ,inertial microbalance,is based on inertial massmeasurement using a hollow tube oscillator.This method isdescribes the design of the apparatus,operating procedure,andthe quality control procedures required to obtain the levels ofprecision and accuracy stated.1.2 This method is suitable for collecting and measuringfilterable particulate matter concentrations in the ranges 0.2mg/m3and above taken in effluent ducts and stacks.1.3 This test method may be used for calibration of auto-mated monitoring systems(AMS).If the emission gas containsunstable,reactive,or semi-volatile substances,the measure-ment will depend on the filtration temperature,and this method(and other in-stack methods)may be more applicable thanout-stack methods for the calibration of automated monitoringsystems.1.4 This test method can be employed in sources having gastemperature up to 200C(392F)and having gas velocitiesfrom 3 to 27 m/s.1.5 This test method includes a description of equipmentand methods to be used for obtaining and analyzing samplesand a description of the procedure used for calculating theresults.1.6 This test method may also be limited from use insampling gas streams that contain fluoride,or other reactivespecies having the potential to react with or within the sampletrain.1.7 Appendix X1 provides procedures for assessment of thespatial variation in particulate matter(PM)concentrationwithin the cross section of a stack or duct test location todetermine whether a particular sampling point or limitednumber of sampling points can be used to acquire representa-tive PM samples.1.8 Appendix X2 provides procedures for reducing thesampling time required to perform calibrations of automatedmonitoring systems where representative PM samples can beacquired from a single sample point and certain other condi-tions are met.1.9 The values stated in SI units are to be regarded as thestandard.The values given in parentheses are for informationonly.1.10 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:2D1356 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 TubesD6331 Test Method for Determination of Mass Concentra-tion of Particulate Matter from Stationary Sources at LowConcentrations(Manual Gravimetric Method)2.2 EPA Methods from 40 CFR Part 60,Appendix A:Method 3A Determination of Oxygen and Carbon DioxideConcentrations in Emissions from Stationary Sources(Instrumental Analyzer Procedure)Method 5 Determination of Particulate Emissions from Sta-tionary SourcesMethod 17 Determination of Particulate Emissions fromStationary Sources(In-Situ Filtration Method)1This 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 Nov.15,2011.Published December 2011.Originallyapproved in 2002.Last previous edition approved in 2005 as D6831 05a.DOI:10.1520/D6831-05A.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.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 2.3 EPA Methods from 40 CFR Part 60,Appendix B:Performance Specification 11 Specifications and Test Proce-dures for Particulate Matter Continuous Emission Moni-toring Systems at Stationary Sources2.4 EPA Methods from 40 CFR Part 63,Appendix A:Method 301 Field Validation of Pollutant MeasurementMethods from Various Waste Media3.Terminology3.1 For definitions of terms used in this test method,refer toTerminology D1356.3.2 Definitions of Terms Specific to This Standard:3.2.1 particulate mattersolid or liquid particles of anyshape,structure,or density(other than water)dis
