Designation:D649422Standard Test Method forDetermination of Asphalt Fume Particulate Matter inWorkplace Atmospheres as Benzene Soluble Fraction1This standard is issued under the fixed designation D6494;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 determination of asphaltfume particulate matter(as benzene soluble fraction)and totalparticulate matter weight in workplace atmospheres using apolytetrafluoroethylene(PTFE)filter methodology.1.2 This procedure has been adapted from NIOSH Method5023(withdrawn prior to 4th edition(1994)and replaced in1998 with NIOSH Method 5042)and OSHA Method 58.Thisadaptation was made to reduce the level of backgroundcontamination providing better reproducibility.1.3 This procedure is compatible with high flow rate per-sonal sampling equipment0.5 to 2.0 L/min.It can be used forpersonal or area monitoring.1.4 The sampling method develops a time-weighted average(TWA)sample and can be used to determine short-termexposure limit(STEL).1.5 The applicable concentration range for the TWA sampleis from 0.2 to 2.0 mg/m3.NOTE1Astudy has suggested candidate solvents for benzene replace-ment.2A less toxic solvent for this analysis would be more appropriate,although the substitution with a solvent other than benzene needs furthervalidations with field data.1.6 The values stated in SI units are to be regarded asstandard.No other units of measurement are included in thisstandard.1.7 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.For more specific precautionary statements,see Section 9.1.8 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:3D1356 Terminology Relating to Sampling and Analysis ofAtmospheresD1357 Practice for Planning the Sampling of the AmbientAtmosphereD4840 Guide for Sample Chain-of-Custody ProceduresD5337 Practice for Flow Rate Adjustment of Personal Sam-pling PumpsD6062 Guide for Personal Samplers of Health-RelatedAero-sol FractionsD8358 Guide forAssessment and Inclusion of Wall Depositsin the Analysis of Single-Stage Samplers for AirborneParticulate Matter2.2 Occupational Safety and Health Administration(OSHA)Methods:4OSHA Method 58 Coal Tar Pitch Volatiles2.3 National Institute for Occupational Safety and Health(NIOSH)Manual of Analytical Methods:5NIOSH Method 5023 Coal Tar Pitch VolatilesNIOSH Method 5042 Benzene Soluble Fraction and TotalParticulate(Asphalt Fume)2.4 Other Documents:ISO/IEC 17025 General requirements for the competence oftesting and calibration laboratories63.Terminology3.1 DefinitionsFor definitions of terms relating to this testmethod,refer to Terminology D1356.1This test method is under the jurisdiction of ASTM Committee D22 on AirQuality and is the direct responsibility of Committee D22.04 on Workplace AirQuality.Current edition approved March 1,2022.Published June 2022.Originallyapproved in 1999.Last previous edition approved in 2015 as D6494 99(2015).DOI:10.1520/D6494-22.2Sutter,B.,Ravera,C.,Hussard,C.,Langlois,E.,“Alternatives for Benzene inthe Extraction of Bitumen Fume from Exposure Sample Media,”Ann.Occup.Hyg.,Vol 60,No.1,2015,pp.101112.3For 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.4Available from Occupational Safety and Health Administration(OSHA),200Constitution Ave.,NW,Washington,DC 20210,http:/www.osha.gov.5Available from National Institute for Occupational Safety and Health(NIOSH),Cincinnati,OH.http:/www.cdc.gov6Available 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 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.13.1.1 asphalt fume particulate matterparticulate mattergenerated during the processing of hot as
