Designation:D409617Standard Test Method forDetermination of Total Suspended Particulate Matter in theAtmosphere(HighVolume Sampler Method)1This standard is issued under the fixed designation D4096;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 provides for sampling a large volumeof atmosphere,1600 to 2400 m3(55 000 to 85 000 ft3),bymeans of a high flow-rate vacuum pump at a rate of 1.13 to1.70 m3/min(40 to 60 ft3/min)(1-4).21.2 This flow rate allows suspended particles having diam-eters of less than 100 m(stokes equivalent diameter)to becollected.However,the collection efficiencies for particleslarger than 20 m decreases with increasing particle size and itvaries widely with the angle of the wind with respect to theroof ridge of the sampler shelter and with increasing speed(5).When glass fiber filters are used,particles within the size rangeof 100 to 0.1 m diameters or less are ordinarily collected.1.3 The upper limit of mass loading will be determined byplugging of the filter medium with sample material,whichcauses a significant decrease in flow rate(see 6.4).For verydusty atmospheres,shorter sampling periods will be necessary.The minimum amount of particulate matter detectable by thismethod is 3 mg(95%confidence level).When the sampler isoperated at an average flow rate of 1.70 m3/min(60 ft3/min)for24 h,this is equivalent to 1 to 2 g/m3(3).1.4 The sample that is collected may be subjected to furtheranalyses by a variety of methods for specific constituents.1.5 The values stated in SI units are to be regarded asstandard.The values given in parentheses are mathematicalconversions to inch-pound units that are provided for informa-tion 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:3D1356 Terminology Relating to Sampling and Analysis ofAtmospheresD1357 Practice for Planning the Sampling of the AmbientAtmosphereD2986 Practice for Evaluation of Air Assay Media by theMonodisperse DOP(Dioctyl Phthalate)Smoke Test(Withdrawn 2004)4D3631 Test Methods for Measuring Surface AtmosphericPressureE1 Specification for ASTM Liquid-in-Glass Thermometers2.2 Other Documents:EPA-600/9-76-005 Quality Assurance Handbook for AirPollution Measurement Systems,Vol I,Principles(De-cember 1984 Rev.)5EPA-600/4-77-027a Quality Assurance Handbook for AirPollution Measurement Systems,Vol II,Ambient AirSpecific Methods53.Terminology3.1 DefinitionsFor definitions of other terms used in thistest method,refer to Terminology D1356.3.2 Definitions of Terms Specific to This Standard:3.2.1 absolute filter,na filter or filter medium of ultra-highcollection efficiency for very small particles(submicrometre1This test method is under the jurisdiction of ASTM Committee D22 on AirQuality and is the direct responsibility of Subcommittee D22.03on AmbientAtmospheres and Source Emissions.Current edition approved Oct.1,2017.Published October 2017.Originallyapproved in 1982.Last previous edition approved in 2009 as D4096 91(2009).DOI:10.1520/D4096-17.2The boldface numbers in parentheses refer to a list of references at the end ofthis standard.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.4The last approved version of this historical standard is referenced onwww.astm.org.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.1 size)so that essentially all particles of interest or of concern arecollected.Commonly,the efficiency is in the region of 99.95%or
