Designation:D631609b1Standard Test Method forDetermination of Total,Combustible and Carbonate Carbonin Solid Residues from Coal and Coke1This standard is issued under the fixed designation D6316;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.1NOTETable A1.1 was editorially corrected in June 2013.1.Scope1.1 This test method covers the determination of total,combustible,and carbonate carbon remaining in the solidbyproducts of combustion from boiler furnaces and similarreactors,including ash,flyash,char,slag,and similar materials.1.2 This test method is intended for the use of industry todetermine the performance of boiler furnaces and similarcombustion reactors and aid in determining the quality of thesolid residue from combustion.1.3 This test method comprises the use of any of severalmethods to determine total carbon content combined with anyof several methods to determine carbonate carbon,and thecalculation,by difference,of the combustible carbon remainingin a sample.1.4 Alternatively,this test method applies to the determina-tion of total carbon remaining in a material after acidificationwith strong acid to evolve carbonate carbon.In this case,thecombustible carbon is the total carbon measured in the sampleafter acidification.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 and health practices and to determine theapplicability of regulatory limitations prior to use.2.Referenced Documents2.1 ASTM Standards:2D121 Terminology of Coal and CokeD513 Test Methods for Total and Dissolved Carbon Dioxidein WaterD1756 Test Method for Determination as Carbon Dioxide ofCarbonate Carbon in Coal(Withdrawn 2013)3D3178 Test Methods for Carbon and Hydrogen in theAnalysis Sample of Coal and Coke(Withdrawn 2007)3D3180 Practice for Calculating Coal and Coke Analysesfrom As-Determined to Different BasesD5373 Test Methods for Instrumental Determination ofCarbon,Hydrogen,and Nitrogen in Laboratory Samplesof Coal and CokeE691 Practice for Conducting an Interlaboratory Study toDetermine the Precision of a Test Method2.2 Other Standards:ANSI/ASME Standard,PTC 38-1980 Determining the Con-centration of Particulate Matter in A Gas Stream and USEPA Standard CFR 60 Appendix A,Method 1743.Terminology3.1 Definitions:3.1.1 For additional definitions of terms used in this testmethod,refer to Terminology D121.3.1.2 carbonate carbon,nthe carbon content present inthe solid products derived from the combustion or reaction ofcoal,coal byproducts,or coke as carbonates and which isnon-combustible in standard industry practice.1This test method is under the jurisdiction of ASTM Committee D05 on Coaland Coke and is the direct responsibility of Subcommittee D05.29 on MajorElements in Ash and Trace Elements of Coal.Current edition approved May 1,2009.Published June 2009.Originallyapproved in 1998.Last previous edition approved in 2009 as D6316-09a.DOI:10.1520/D6316-09BE01.2For 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.3The last approved version of this historical standard is referenced onwww.astm.org.4Available from American National Standards Institute(ANSI),25 W.43rd St.,4th Floor,New York,NY 10036,http:/www.ansi.org.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 3.1.3 combustible carbon,ncarbon content remaining inthe solid products derived from the combustion or reaction ofcoal,coal byproducts,or coke,exclusive of carbonate in anyform.3.1.4 total carbon,ncarbon content remaining in the solidproducts derived from the combustion or reaction of coal,coalbyproducts,or coke,inclusive of carbonate in any form.4.Summary of Test Method4.1 Total CarbonThe determination of total carbon ismade by the oxidative thermal decomposition of a weighedquantity of sample in a closed system and,after completeoxidation and purification of the resulting gaseous products,measurement of the carbon dioxide produced by one of severalmethods.4.1.1 Absorptive Determination of Total CarbonTheevolved carbon dioxide is fixed on an absorption train and ismeasured quantitatively by weighing the absorbent(see TestMethods D3178).4.1.2 Instrumental Determination of Total CarbonThecarbon dioxide is measured quantitatively by an electronicdetection system calibrated against an appropriate referencestandard(see Test Methods D5373).4.2 Carbon
