Designation:D8142171Standard Test Method forDetermining Chemical Emissions from Spray PolyurethaneFoam(SPF)Insulation using Micro-Scale EnvironmentalTest Chambers1This standard is issued under the fixed designation D8142;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.1NOTEEditorially added research report information to Section 16 and Appendix X1 in February 2020.1.Scope1.1 This test method is used to identify and to measure theemissions of volatile organic compounds(VOCs)emitted fromsamples of cured spray polyurethane foam(SPF)insulationusing micro-scale environmental test chambers combined withspecific air sampling and analytical methods for VOCs.1.2 Specimens prepared from product samples are main-tained at specified conditions of temperature,humidity,airflowrate,and elapsed time in micro-scale chambers that aredescribed in Practice D7706.Air samples are collected peri-odically at the chamber exhaust at the flow rate of themicro-scale chambers.1.2.1 Samples for formaldehyde and other low-molecularweight carbonyl compounds are collected on treated silica gelcartridges and are analyzed by high performance liquid chro-matography(HPLC)as described in Test Method D5197 andISO 16000-3.1.2.2 Samples for other VOCs are collected on multi-sorbent samplers and are analyzed by thermal-desorption gaschromatography/mass spectrometry(TD-GC/MS)as de-scribed in U.S.EPA Compendium Method TO-17 and ISO16000-6.1.3 This test method is intended specifically for SPF insu-lation products.Compatible product types include twocomponent,high pressure and two-component,low pressureformulations of open-cell and closed-cell SPF insulation.1.4 VOCs that can be sampled and analyzed by this testmethod generally include organic blowing agents such as1,1,1,3,3-pentafluoropropane,formaldehyde and other carbo-nyl compounds,residual solvents,and some amine catalysts.Emissions of some organic flame retardants can be measuredafter 24 h with this method,such as tris(chloroisopropyl)phosphate(TCPP).1.5 This test method does not cover the sampling andanalysis of methylene diphenyl diisocyanate(MDI)or otherisocyanates.1.6 Area-specific and mass-specific emission rates are quan-tified at the elapsed times and chamber conditions as specifiedin 13.2 and 13.3 of this test method.1.7 This test method is used to identify emitted compoundsand to estimate their emission factors at specific times.Theemission factors are based on specified conditions,therefore,use of the data to predict emissions in other environments maynot be appropriate and is beyond the scope of this test method.The results may not be representative of other test conditions orcomparable with other test methods.1.8 This test method is primarily intended for freshlyapplied,SPF insulation samples that are sprayed and packagedas described in Practice D7859.The measurement of emissionsduring spray application and within the first hour followingapplication is outside of the scope of this test method.1.9 This test method can also be used to measure theemissions from SPF insulation samples that are collected frombuilding sites where the insulation has already been applied.Potential uses of such measurements include investigations ofodor complaints after product application.However,the spe-cific details of odor investigations and other indoor air quality(IAQ)investigations are outside of the scope of this testmethod.1.10 The values stated in SI units are to be regarded asstandard.No other units of measure are used.1.11 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.1.12 This international standard was developed in accor-dance with internationally recognized principles on standard-ization established in the Decision on Principles for the1This 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.1,2017.Published October 2017.DOI:10.1520/D8142-17E01.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.Development of International Standards,Guides and Recom-mendations issued by the World Trade Organization TechnicalBarriers to Trade(TBT)C
