Designation:D606017Standard Test Method forSampling of Process Vents with a Portable GasChromatograph1This standard is issued under the fixed designation D6060;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 describes a method for direct samplingand analysis of process vents for volatile organic compound(VOC)vapors and permanent gases using a portable gaschromatograph(GC).1.2 This test method is applicable to analysis of permanentgases such as oxygen(O2),carbon dioxide(CO2)and nitrogen(N2),as well as vapors from organic compounds with boilingpoints up to 125C.1.3 The detection limits obtained will depend on the por-table gas chromatograph and detector used.Detectors availableinclude but are not limited to thermal conductivity,photoionization,argon ionization,and electron capture.Forinstruments equipped with thermal conductivity detectors,typical detection limits are one to two parts per million byvolume(ppm(v)with an applicable concentration range tohigh percent by volume levels.For instruments with photoion-ization detectors detection limit of one to ten parts per billionby volume(ppb(v)are obtainable with a concentration rangefrom 1000 to 2000 ppm(v).The argon ionization detector hasan achievable detection limit of one(ppb(v),while theelectron capture detector has an achievable detection limit ofone part per trillion by volume(ppt(v)for chlorinated com-pounds.1.4 The applicability of this test method should be evaluatedfor each VOC by determining stability,reproducibility,andlinearity.1.5 The appropriate concentration range must also be deter-mined for each VOC,as the range will depend on the vaporpressure of the particular VOC.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.Refer to Section 8 on Hazards for additional safety precautions.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:2D1356 Terminology Relating to Sampling and Analysis ofAtmospheresD3154 Test Method for Average Velocity in a Duct(PitotTube Method)D3464 Test Method for Average Velocity in a Duct Using aThermal AnemometerE355 Practice for Gas Chromatography Terms and Relation-ships2.2 Other Document:NFPA 70 National Electrical Code3NFPA 496 Standard for Purged and Pressurized Enclosuresfor Electrical Equipment33.Terminology3.1 DefinitionsFor the definition of terms used in this testmethod,refer to Terminology D1356 and Practice E355.3.2 Definitions of Terms Specific to This Standard:3.2.1 portable,nrefers to gas chromatograph with internalbattery,internal sample pump,and internal/rechargeable carriergas supply cylinder.1This 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 Oct.1,2017.Published October 2017.Originallyapproved in 1996.Last previous edition approved in 2009 as D6060 96(2009).DOI:10.1520/D6060-17.2For 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 National Fire Protection Association(NFPA),1 BatterymarchPark,Quincy,MA 02169-7471,http:/www.nfpa.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.1 4.Summary of Test Method4.1 One end of a sampling line(typically 6 mm outsidediameter TFE-fluorocarbon tubing)is connected to a tee in aprocess vent and the other end to a condensation trap(see 6.1),which is connected to a gas sampling bulb.The outlet of thegas sampling bulb is connected to a sampling pump set at aflow rate of 0.5 to 2 L/min.The sample line from the portablegas chromatogra
