Volatile organic compounds (VOC) emitted by building materials have been recognized as a major problem and can affect human health and semiconductor processes. lt is widely known that the emission characteristics are affected by temperature, air flow etc., however the research about humidity is not conclusive. Therefore this study conducted that under different humidity conditions, measurements of 7 VOC's diffusion coefficients were investigated. The measured diffusion coefficients were substituted for physical models, and used for predicting the emission flux of VOC's from the PVC flooring sheet. The physical models were well in good agreement with the experiment data, indicating that the effect of humidity on the emission flux was estimated through internal diffusion.
