Designation:D429217Standard Test Method forDetermination of Vibrated Bulk Density of CalcinedPetroleum Coke1This standard is issued under the fixed designation D4292;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.Scope*1.1 This test method covers the determination of bulkdensity of a representative 2 kg sample of calcined petroleumcoke,after vibration to increase compaction.1.2 The procedure is limited to particles passing through a6.68 mm opening sieve(equivalent to a 0.265 in.USA Series)and retained on a 0.21 mm opening sieve(equivalent to a70 mesh USA Series).Further,the procedure is limited to aspecific test sample having particles retained between screenshaving openings that differ by a factor of less than2=2andpreferably less than 2.1.3 The values stated in SI units are to be regarded asstandard.No other units of measurement are included in thisstandard.1.4 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.1.5 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:2D346 Practice for Collection and Preparation of CokeSamples for Laboratory AnalysisD2013 Practice for Preparing Coal Samples for AnalysisD2234/D2234M Practice for Collection of a Gross Sampleof CoalD4057 Practice for Manual Sampling of Petroleum andPetroleum ProductsD5709 Test Method for Sieve Analysis of Petroleum CokeD6969 Practice for Preparation of Calcined Petroleum CokeSamples for AnalysisD6970 Practice for Collection of Calcined Petroleum CokeSamples for AnalysisE11 Specification for Woven Wire Test Sieve Cloth and TestSieves3.Terminology3.1 Definitions of Terms Specific to This Standard:3.1.1 as-calcined particles,nof coke,those particles thathave not been subject to laboratory crushing.3.1.2 bulk density,nof coke,the ratio of the mass of acollection of particles of a specified particle size range to thevolume occupied.3.1.3 gross sample,nthe original,uncrushed,representa-tive portion taken from a shipment or lot of coke.3.1.4 laboratory crushed particles,nof coke,those par-ticles of petroleum coke that have been crushed in thelaboratory.4.Summary of Test Method4.1 After appropriate crushing of the calcined coke,usingboth the jaw crusher and roll crusher,the test volume of 100 gis measured after vibration and the bulk density is calculated.5.Significance and Use5.1 Vibrated bulk density,VBD,is an indicator of calcinedpetroleum coke porosity,which affects its suitability for use inpitch-bonded carbon applications.(WarningVibrated bulkdensity for a sample of calcined petroleum coke is stronglydependent upon average particle size and particle size range.Bulk density tends to increase with decreasing coke size.Anarrow particle size range for this test minimizes the possibilityfor variation due to skewing of the test sample toward eitherscreen defining the sample.Particle size range tested should beagreed upon by the purchaser and supplier.)1This test method is under the jurisdiction of ASTM Committee D02 onPetroleum Products,Liquid Fuels,and Lubricants and is the direct responsibility ofSubcommittee D02.05 on Properties of Fuels,Petroleum Coke and Carbon Material.Current edition approved Dec.1,2017.Published January 2018.Originallyapproved in 1992.Last previous edition approved in 2010 as D4292 10.DOI:10.1520/D4292-17.2For 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.*A Summary of Changes section appears at the end of this standardCopyright 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 NOTE1An example of the use of VBD to characterize coke forprebaked anodes for aluminum smelting is reported by Belitskus3whofound particles passing through a 0.59 mm opening,No.30,sieve andretained on a 0.30 mm opening,No.50,sieve to be
