B-12 Study on measurement of Di-2-ethylhezyl phthalate from building products by Micro chamber method

Abstract

It is examined as a standardized method for the Micro chamber method to measure SVOC emitted from building materials. DEHP is classified as SVOC and widely used as plasticizers in polyvinyl chloride (PVC). The indoor guideline of the Japan Ministry of Health, Labour and Welfare for DEHP was set at 120 μg/m^3. In this study, the authors measured DEHP emitted from PVC wallpaper and flooring using the Micro chamber method. And we evaluated various experiments concerning this method. In these experiments it was found that the silane finishing of the internal chamber surface was effectively in the measurement of SVOC emitted.
