Designation:D814518Standard Practice forSampling of Green Petroleum Coke1This standard is issued under the fixed designation D8145;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.INTRODUCTIONGreen petroleum coke is a byproduct of certain oil refining technologies but has multiple uses,suchas a solid mineral fuel or a key constituent of making anodes.The chemical and physicalcharacteristics of green petroleum coke,particularly the moisture content,are not always distributedequally in the different sized particles.As such,the sampling of green petroleum coke must follow thegeneral sampling principals of capturing the particle size distribution of the consignment into the grosssample that is collected to represent it.Green petroleum coke sampling has relied on the sampling standards for Coal and Coke underASTM Subcommittee D05.05 for guidance on how to collect and prepare samples,in particular,Practice D2234/D2234M for the Collection of a Gross Sample of Coal,Practice D2013/D2013M forthe Preparation of Coal Samples for Analysis,and Practice D346 for the Collection and Preparationof Coke Samples for Laboratory Analysis have been used,among others.With the growing use ofmechanical sampling equipment,Practice D7430 for the Mechanical Sampling of Coal has been addedto the mix.The above cited standards are useful,but do not account for some of the uniquecharacteristics of petroleum coke,which has led to widespread confusion as to which parts areapplicable,especially Practice D346,which is really used for coke made from coal and not frompetroleum refining.This practice gives guidelines for the user on how to sample green petroleum coke.The intent is notto write a standalone standard for green petroleum coke but to direct the user as to how to apply theD05.05 coal standards already in existence.1.Scope1.1 This practice primarily references Practice D2234/D2234M and applies its sampling principles to green petro-leum coke.Green petroleum coke is typically more homoge-neous than coal and this practice provides specific guidance forthe application of D05.05 coal standards to the sampling ofgreen petroleum coke.1.1.1 Practice D2234/D2234M references the four condi-tions of collecting sample increments:Condition A(StoppedBelt Cut),Condition B(Full-stream Cut),Condition C(Part-stream Cut),and Condition D(Stationary Sampling).Thispractice directs the user to the appropriate coal standard toapply to each condition,as well as key considerations.1.2 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.1.3 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:2D121 Terminology of Coal and CokeD346 Practice for Collection and Preparation of CokeSamples for Laboratory AnalysisD2013/D2013M Practice for Preparing Coal Samples forAnalysisD2234/D2234M Practice for Collection of a Gross Sampleof Coal1This practice is under the jurisdiction of ASTM Committee D02 on PetroleumProducts,Liquid Fuels,and Lubricants and is the direct responsibility of Subcom-mittee D02.05 on Properties of Fuels,Petroleum Coke and Carbon Material.Current edition approved May 1,2018.Published July 2018.DOI:10.1520/D8145-18.2For 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 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 D5709 Test Method for Sieve Analysis of Petroleum CokeD6609 Guide for Part-Stream Sampling of CoalD6883 Practice for Manual Sampling of Stationary Coalfrom Railroad Cars,Barges,Trucks,or StockpilesD7430 Practice for Mechanical Sampling of CoalE456 Terminology Relating to Quality and Statistics3.Terminology3.1 DefinitionsDefinitions applicable to this practice arelisted in Terminology D121.3.2 Definitions of Terms Specific to
