Designation:D8108211Standard Test Method forDetermination of Particulate Matter Mass from Light DutyMobile Sources(Gravimetric Method)1This standard is issued under the fixed designation D8108;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.1NOTEResearch report information was updated editorially in July 2022.1.Scope1.1 This test method covers a procedure for the gravimetricdetermination of particulate matter(PM)collected from dilutedlight duty vehicle exhaust.It is applicable to mass rates from0.32 to 32 mg/km(0.2 to 20 mg/mile).1.2 Diluted exhaust is passed through pre-weighed filtermedia which is re-weighed after sampling.The difference inweight is used to determine particulate mass,which is thenused with other data to calculate the distance specific emis-sions.1.3 The particulate materials that are measured using thistest method are generated by a vehicle following the PMstandard applicable portions of the United States Environmen-tal Protection Agency(EPA)and California Air ResourcesBoard(CARB)driving schedules and test procedures fordetermining the emissions of light duty vehicles.For otherjurisdictions,consult regional regulations for applicability ofthese test procedures.These test procedures are referenced inAnnex A3 of this document.1.4 The primary intent of this test method is to summarizethe PM measurement test procedures as defined by the EPAandCARB(40 CFR Parts 1066,1065,86.101,and CARB testprocedures for hybrid vehicle testing).NOTE1Some requirements are generalized from core references forsimplicity and to provide guidance for users applying the principals in thisstandard to regions not governed by EPA and CARB regulation.Forspecific details,reference the regulated procedures.1.5 The values stated in SI units are to be regarded asstandard.The values given in parentheses after SI units areprovided for information only and are not considered standard.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,health,and environmental practices and deter-mine the applicability of regulatory limitations prior to use.1.7 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:2D1356 Terminology Relating to Sampling and Analysis ofAtmospheresE177 Practice for Use of the Terms Precision and Bias inASTM Test MethodsE691 Practice for Conducting an Interlaboratory Study toDetermine the Precision of a Test Method2.2 ISO Standards:3ISO 14644-1 Cleanrooms and associated controlled environ-ments Part 1:Classification of air cleanliness byparticle concentration2.3 Government Regulations:CARB California Exhaust Emission Standards and TestProcedures for 2018 and Subsequent Model Zero-Emission Vehicles and Hybrid Electric Vehicles,in thePassenger Car,Light-Duty Truck and Medium-Duty Ve-hicle Classes Sections F(HEVs)and G(PHEVs)4EPA 40 CFR Part 86,Appendix I5EPA 40 CFR Part 86.1015EPA 40 CFR Part 106551This 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 May 1,2021.Published May 2021.Originallyapproved in 2020.Last previous edition approved in 2020 as D8101 20.DOI:10.1520/D8108-21E01.2For 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.3Available from International Organization for Standardization(ISO),ISOCentral Secretariat,BIBC II,Chemin de Blandonnet 8,CP 401,1214 Vernier,Geneva,Switzerland,http:/www.iso.org.4Available from California Air Resources Board(CARB),1001 I Street,Sacramento,CA 95814,https:/ww2.arb.ca.gov.5Available from United States Environmental ProtectionAgency(EPA),WilliamJefferson Clinton Bldg.,1200 Pennsylvania Ave.,NW,Washington,DC 20460,http:/www.epa.gov.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.1EPA 40 CFR Part 106653.Terminolog
