Designation:D770611Standard Practice forRapid Screening of VOC Emissions from Products UsingMicro-Scale Chambers1This standard is issued under the fixed designation D7706;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 practice describes a micro-scale chamber apparatusand associated procedures for rapidly screening materials andproducts for their vapor-phase emissions of volatile organiccompounds(VOCs)including formaldehyde and other carbo-nyl compounds.It is intended to complement,not replacereference methods for measuring chemical emissions forexample,small-scale chamber tests(Guide D5116)and emis-sion cell tests(Practice D7143).1.2 This practice is suitable for use in and outside oflaboratories,in manufacturing sites and in field locations withaccess to electrical power.1.3 Compatible material/product types that may be tested inthe micro-scale chamber apparatus include rigid materials,dried or cured paints and coatings,compressible products,andsmall,irregularly-shaped components such as polymer beads.1.4 This practice describes tests to correlate emission resultsobtained from the micro-scale chamber with results obtainedfrom VOC emission reference methods(for example,GuideD5116,Test Method D6007,Practice D7143,and ISO 16000-9and ISO 16000-10).1.5 The micro-scale chamber apparatus operates at moder-ately elevated temperatures,30C to 60C,to eliminate theneed for cooling,to reduce test times,boost emission rates,andenhance analytical signals for routine emission screening,andto facilitate screening of semi-volatile VOC(SVOC)emissionssuch as emissions of some phthalate esters and other plasticiz-ers.1.6 Gas sample collection and chemical analysis are depen-dent upon the nature of the VOCs targeted and are beyond thescope of this practice.However,the procedures described inTest Method D7339,Practice D6196 and ISO 16000-6 foranalysis of VOCs and in Test Method D5197 and ISO 16000-3for analysis of formaldehyde and other carbonyl compoundsare applicable to this practice.1.7 The values stated in SI units are to be regarded asstandard.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 ofAtmospheresD1914 Practice for Conversion Units and Factors Relating toSampling and Analysis of AtmospheresD5116 Guide for Small-Scale Environmental Chamber De-terminations of Organic Emissions from Indoor Materials/ProductsD5197 Test Method for Determination of Formaldehyde andOther Carbonyl Compounds inAir(Active Sampler Meth-odology)D6007 Test Method for Determining Formaldehyde Concen-trations in Air from Wood Products Using a Small-ScaleChamberD6196 Practice for Selection of Sorbents,Sampling,andThermal Desorption Analysis Procedures for Volatile Or-ganic Compounds in AirD5337 Practice for Flow Rate Adjustment of Personal Sam-pling PumpsD7143 Practice for Emission Cells for the Determination ofVolatile Organic Emissions from Indoor Materials/ProductsD7339 Test Method for Determination of Volatile OrganicCompounds Emitted from Carpet using a Specific SorbentTube and Thermal Desorption/Gas Chromatography1This practice is under the jurisdiction ofASTM Committee D22 on Air Qualityand is the direct responsibility of Subcommittee D22.05 on Indoor Air.Current edition approved March 1,2011.Published March 2011.DOI:10.1520/D7706-11.2For 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 2.2 ISO Standards:3ISO 16000-3 Determination of formaldehyde and other car-bonyl compounds Active sampling methodISO 16000-6 Determination of volatile organic compoundsin indoor and test chamber air by active sampling onTenaxTAsorbent,thermaldesorptionandgas-chromatography using MS/FIDISO 16000-9 Indoor airPart 9:Determination of the emis-sion of volatile organic compounds Emission testchamber methodISO 16000-10 Indoor airPart 10:Determination of theemission of volatile organic compounds Emission testcell method2.3 Other Standard:4US EPA Method TO-17 Determination of volatile organiccompounds in ambient air using active sampling ontosorbent tubes3.Terminology3.1 DefinitionsFor definitions and terms commonly usedfor sampling and analysis of
