In this study, laboratory experiments were carried out for the development of on-site measurement methods using microchambers. In addition, the SVOC emission rate from floor materials in a general house was measured using the developed on-site measurement method. The developed on-site measurement device has less contamination from fresh air supply, background and travelblanks. In addition, the on-site measurement method was highly consistent with the microchamber measurement results. Furthermore, it was confirmed that the measurement results of the SVOC emission rate from the floor materials in actual houses were within the measurement range of new products.
