Designation:D814317(Reapproved 2022)Standard Test Method forDetermination of the EU-8 List of PAH Compounds inCarbon Black1This standard is issued under the fixed designation D8143;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 covers the qualitative and quantitativedetermination of the EU-8 list of polycyclic aromatic hydro-carbons(PAH)on carbon black.The EU-8 list of PAHcompounds is given in Table 1.The procedure involves Soxhletextraction with toluene followed by extract analysis using gaschromatography with mass spectrometry(GC/MS).Thismethod is not intended to test for U.S.Food and DrugAdministration(FDA21 CFR 178.3297)compliance of carbonblacks used for indirect food contact applications.1.2 UnitsThe values stated in SI units are to be regardedas the standard.No other units of measurement are included inthis standard.1.3 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.1.4 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 Federal Standard:221 CFR 178.3297 Indirect Food Additives:Adjuvants,Pro-ductions Aids,and Sanitizers,Colorants for Polymers3.Terminology3.1 Definitions of Terms Specific to This Standard:3.1.1 polycyclic aromatic hydrocarbon,PAH,norganiccompound(s)that consist of chemical structures of alternatingsingle and double bonds of a ring like nature(for example,benzene),with no heteroatom or other substituents;frequentlythe rings are fused to make larger chemical structures.3.1.1.1 DiscussionPAH naturally occur in oil,coal,and tardeposits;are produced by the incomplete combustion ofhydrocarbons;and occur in many other products and processes.3.1.2 EU-8 PAH compound list,na list of eight polycyclicaromatic hydrocarbons that are specified by the CommissionRegulation(EU)1272/2013(December 6,2013)3amendingAnnex XVII to Regulation(EC)1907/2006 of the EuropeanParliament and of the Council on the Registration,Evaluation,Authorisation and Restriction of Chemicals(REACH)asregards polycyclic aromatic hydrocarbons(2013)OJ L328/69.3.1.2.1 DiscussionRegulation(EU)No.1272/2013 setsPAH concentration limits on finished products specified bytheir application.The regulation does not refer directly tocarbon black,though in many instances and for formulationpurposes there is a need to know the quantitative,extractablePAH content present in carbon black that will become part ofthe finished product.In addition,no specific test method hasbeen defined by the regulation for testing finished products orraw materials used in the finished products.4.Summary of Test Method4.1 A portion of carbon black is Soxhlet-extracted withtoluene for 48 h.The extract is concentrated and subsequentlyanalyzed for specific PAH compounds by gas chromatographywith mass spectrometry(GC/MS).Each PAH compound isquantified individually using internal and external standards.5.Significance and Use5.1 This test procedure is used to determine the individualconcentrations of the PAH compounds in the EU-8 list ex-tracted from carbon black by the means of a Soxhlet extractionapparatus with toluene.1This test method is under the jurisdiction of ASTM Committee D24 on CarbonBlack and is the direct responsibility of Subcommittee D24.66 on Environment,Health,and Safety.Current edition approved June 1,2022.Published July 2022.Originally approvedin 2017.Last previous edition approved in 2017 as D8143 17.DOI:10.1520/D8143-17R22.2Available from U.S.Government Printing Office,Superintendent ofDocuments,732 N.Capitol St.,NW,Washington,DC 20401-0001,http:/www.access.gpo.gov.3Commission Regulation(EU)No 1272/2013 of 6 December 2013.Available athttp:/eur-lex.europa.eu/eli/reg/2013/1272/oj.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.16.Apparatus6.1 Soxhlet Extractor with Reflux Condenser,50 or 100 cm3capacity.6.2 Extraction Thimbles,glass or cellulose,approximately50 to 70 cm3capacity.For instance,gl
