6、ee Guide D5116.1.3 VOC concentrations in the environmental test chamberare determined by adsorption on an appropriate single adsor-bent tube or multi-adsorbent tube,followed by thermal desorp-tion and combined gas chromatograph/mass spectrometry(GC-MS)or gas chromatograph/flame ionization detection(
7、GC-FID).The air sampling procedure and the analytical methodrecommended in this practice are generally valid for theidentification and quantification of VOCs with saturation vaporpressure between 500 and 0.01 kPa at 25C,depending on theselection of adsorbent(s).NOTE1VOCs being captured by an adsorbe
8、nt tube depend on theadsorbent(s)and sampling procedure selected(see Practice D6196).Theuser should have a thorough understanding of the limitations of eachadsorbent used.Although canisters can be used to sample VOCs,thisstandard is limited to sampling VOCs from the chamber air usingadsorbent tubes.
9、1.4 The emission factors determined using the above pro-cedure describe the emission characteristics of the specimenunder the standard test condition.These data can be useddirectly to compare the emission characteristics of differentproducts and to estimate the emission rates up to one monthafter th
10、e production.They shall not be used to predict theemission rates over longer periods of time(that is,more thanone month)or under different environmental conditions.1.5 Emission data from chamber tests can be used forpredicting the impact of wood-based panels on the VOCconcentrations in buildings by
