erials at various manufacturing steps for surface finishing materials as determined by the VOC analyzer.
Fig. 5 presents concentrations of the four indicated VOCs from eachsample,asdeterminedbytheVOCanalyzer.Fromallsamples, xylene was the highest detected compound. The second highest detected compound was ethylbenzene, followed by toluene and styrene. In the VOC analyzer test, we defined TVOC as the sum of the four detected main aromatic hydrocarbon gases: toluene, ethylbenzene, xylene and styrene. Although it was hard to compare directly the FLEC results because these data were based only on the sum of four VOC compounds, when it was compared to the results of Table 5, the VOC analyzer was found to be a suitable pre-test method for application as a TVOC emission test [26]. The TVOC emission results were also shown to be similar to those of FLEC.
