Designation:D595502(Reapproved 2012)1Standard Test Methods forEstimating Contribution of Environmental Tobacco Smoketo Respirable Suspended Particles Based on UVPM andFPM1This standard is issued under the fixed designation D5955;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.1NOTEReapproved with editorial changes in April 2012.1.Scope1.1 These test methods pertain to the sampling/analysis ofrespirable suspended particles(RSP)and the estimation of theRSP fraction attributable to environmental tobacco smoke(ETS).These test methods are based on collection of total RSPon a membrane filter,extracting the collected material inmethanol,and measuring total ultraviolet absorbance orfluorescence,or both,of this extract.The correspondingmethods of estimation are termed ultraviolet particulate matter(UVPM)and fluorescent particulate matter(FPM),respec-tively.1.2 These test methods are compatible with,but do notrequire the determination of solanesol,which is also used toestimate the contribution of ETS to RSP(see Test MethodD6271).1.3 The sampling components consist of a preweighed,1.0-m pore size polytetrafluoroethylene(PTFE)membranefilter in a filter cassette connected on the inlet end to a particlesize separating device and,on the outlet end,to a samplingpump.These test methods are applicable to personal and areasampling.1.4 These test methods are limited in sample duration onlyby the capacity of the membrane filter(about 2000 g).Thesetest methods have been evaluated up to a 24-h sample durationwith a minimum sample duration of at least 1 h.1.5 Limits of detection(LOD)and quantitation(LOQ)forthe UVPM test method at a sampling rate of 2 L/min are,respectively,2.5 g/m3and 8.3 g/m3for a 1-h sample durationand 0.3 g/m3and 1.0 g/m3for an 8-h sample duration.TheLOD and LOQ for the FPM test method at a sampling rate of2 L/min are,respectively,1.4 g/m3and 4.7 g/m3for a 1-hsample duration and 0.2 g/m3and 0.6 g/m3for an 8-h sampleduration.1.6 UnitsThe values stated in SI units are to be regardedas standard.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 and health practices and determine the applica-bility of regulatory limitations prior to use.Specific precau-tionary information is given in 13.6.2.Referenced Documents2.1 ASTM Standards:2D1356 Terminology Relating to Sampling and Analysis ofAtmospheresD1357 Practice for Planning the Sampling of the AmbientAtmosphereD3631 Test Methods for Measuring Surface AtmosphericPressureD5337 Practice for Flow Rate Adjustment of Personal Sam-pling PumpsD6271 Test Method for Estimating Contribution of Environ-mental Tobacco Smoke to Respirable Suspended ParticlesBased on Solanesol3.Terminology3.1 DefinitionsFor definitions of terms used in these testmethods,refer to Terminology D1356.3.2 Definitions of Terms Specific to This Standard:3.2.1 environmental tobacco smoke(ETS)an aged,dilutecomposite of exhaled tobacco smoke(exhaled mainstreamsmoke)and smoke from tobacco products(sidestream smoke).3.2.2 environmental tobacco smoke particulate matter(ETS-PM)the particulate phase of ETS.1These test methods are under the jurisdiction of ASTM Committee D22 on AirQuality and are the direct responsibility of Subcommittee D22.05 on Indoor Air.Current edition approved April 1,2012.Published July 2012.Originallyapproved in 1996.Last previous edition approved in 2007 as D5955-02(2007).DOI:10.1520/D5955-02R12E01.2For 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.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 3.2.3 fluorescent particulate matter(FPM)an estimationof the contribution of ETS particulate matter to RSP obtainedby comparing the fluorescence intensity of the RSP sample tothat of a surrogate standard.3.2.4 respirable suspended particles(RSP)particleswhich,when captured by a size-selective sampling device,conform to a collection efficiency curve with a median cutpointat an aerodynamic diameter of 4.0 m(1).33.2.5 surrogate standarda chemical whose concentrationhas been related quantitatively to a known concentration ofETS-PM.3.2.6 2,2,4,4-tetrahydroxybenzophenone(THBP)aUVPM surrogate standard.3.2.7 ultraviolet particulate matter(UVPM)an estimationof the contribution of ETS particulate matter to RSP obtainedby comparing the ultraviolet absorbance of the RSP sample tothat of a surrogate standard.4.Summary of Test Methods4.1
