Designation:D733912Standard Test Method forDetermination of Volatile Organic Compounds Emitted fromCarpet using a Specific Sorbent Tube and ThermalDesorption/Gas Chromatography1This standard is issued under the fixed designation D7339;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 an analytical procedure foridentifying and quantifying the masses of individual volatileorganic compounds(individual VOCs or IVOCs)that areemitted into a flow of air from carpet specimens and collectedon sorbent sampling tubes during emissions testing.1.2 This test method will be used in conjunction with astandard practice for sampling and preparing carpet specimensfor emissions testing.If a specific chamber practice is notavailable for the carpet specimens,this standard test methodshould be used in conjunction with approved standard practicesfor emissions testing and sample preparation.1.3 When used in conjunction with standard practices forcarpet specimen preparation and collection of vapor-phaseemissions,this test method will provide a standardized meansof determining the levels of IVOC in the exhaust stream of theemissions test chamber/cell.If this test method is used with areliable practice for emissions testing,these IVOC levels canbe used to determine the emission rate from a unit quantity(usually surface area)of the sample material under test.1.4 VOCs in the exhaust stream of an emissions test deviceare collected on thermal desorption tubes packed with aspecific combination of sorbents using active(pumped)sam-pling.(See Practice D6196 for a more general description ofvapor collection using pumped sampling onto sorbent tubes).The samples are analyzed by thermal desorption(TD)with gaschromatography and mass spectrometry detection(GC/MS)and/or flame ionization detection(FID)depending upon therequirements of the specific materials emissions testing/certification protocol.1.5 This test method can be used for the measurement ofmost GC-compatible organic vapors ranging from the approxi-mate volatility from n-hexane to n-hexadecane(that is,com-pounds with vapor pressures ranging from 16 kPa to 4 10-4kPa at 25C).Properties other than a compounds vaporpressure such as affinity for the sorbent may need to be takeninto account.Compounds with vapor pressures outside thisrange may or may not be quantifiable by this method.However,qualitative data concerning the identity of acompound(s),outsidethestatedvolatilityrangeforquantitation,may still be useful to the user.The method can beapplied to analytes over a wide concentration rangetypically1 g/m3to 1 mg/m3concentration of vapor in the exhaust airfrom the emission cell or chamber.1.6 This test method is not capable of quantifying allcompounds which are emitted from carpets.See the appropri-ate test practices/methods for determining other compoundsthat are not amenable to analysis by gas chromatography(thatis,Test Method D5197 for the determination of aldehydes).1.7 UnitsThe values stated in SI units are to be regardedas standard.No other units of measurement are included in thisstandard.1.8 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.2.Referenced Documents2.1 ASTM Standards:2D1356 Terminology Relating to Sampling and Analysis ofAtmospheresD3686 Practice for Sampling Atmospheres to Collect Or-ganic Compound Vapors(Activated Charcoal Tube Ad-sorption Method)D5116 Guide for Small-Scale Environmental Chamber De-terminations of Organic Emissions from Indoor Materials/ProductsD5197 Test Method for Determination of Formaldehyde and1This test method is under the jurisdiction of ASTM Committee D22 on AirQuality and is the direct responsibility of Subcommittee D22.05 on Indoor Air.Current edition approved Oct.15,2012.Published November 2012.Originallyapproved in 2007.Last previous edition approved in 2007 as D7339 07.DOI:10.1520/D7339-12.2For 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 Other Carbonyl Compounds inAir(Active Sampler Meth-odology)D5337 Practice for Flow Rate Adjustment of Personal Sam-pling PumpsD6196 Practice for Selection of Sorbents,Sampling,andThermal Desorption Analysis Procedures for Volatile Or-ganic Compounds in AirD6670 Practice for Full-Scale Chamber Determination ofVolatile Or
