Abstract
The Field and Laboratory Emission Cell (FLEC) has been tested and evaluated for qualitative and quantitative emission testing of volatile organic compounds (VOCs) from building products. An air supply control unit has been developed and its performance is reported in the range of 100 to 500 mllmin airflows. The recovery in the FLEC has been tested with a new performance test kit with dodecane and 2-ethylhexanol, respectively. Additionally, five VOCs emitted from a liquid floor wax were measured in the FLEC and in a small climate chamber. The first order rate constants (k1) and the initial emission rates (R0) obtained from the time versus concentration data measured over 24 hours proved to be comparable. The application of FLEC in a complaint case of malodorous linoleum in an office building showed that artificial wetting of the linoleum had a marked influence on the qualitative offgassing of odorous VOCs such as fatty acids, glycol ethers, and 2-decenal.
