MEASUREMENT OF VOC AND SVOC EMITTED FROM AUTOMOTIVE INTERIOR MATERIALS BY THERMAL DESORPTION TEST CHAMBER METHOD

摘要

In order to clarify the mechanism of indoor air quality in vehicle cabins, it is important to measure correctly the emission rates of volatile organic compounds (VOC) and semi-volatile organic compounds (SVOC) from automotive interior materials. In this study, we measured VOC and SVOC emitted from automotive interior materials using the Thermal Desorption Test Chamber method (TDC method), which quantified emission rates (ER) of VOC and SVOC of materials at actual temperature. This method was composed of two measurement steps.First, VOC emitted from material in the glass chamber was measured. Second, SVOC adsorbed on the internal chamber surface was measured. As a result, VOC emitted (Toluene, Ethylbenzene, Xylene, Styrene,Cyclohexanone, etc.) and SVOC emitted (BHT, DEP, DBP, DEHP, DINP, DOA, etc.) were confirmed. These results indicated that measurements of VOC and SVOC emitted from automotive interior materials could be carried out effectively.
