3、bruary 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 VO
4、Cs.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 ch
5、ambers.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-s
6、orbent 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 a
7、nd 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
8、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 emi
9、ssion 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,
10、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 insulatio
