Abstract

Three experimental methods have been investigated in order to evaluate their ability to measure the sorption and diffusion properties of indoor materials: 1) micro-balance method (measurement of the sorption capacity of a material by weighing a test specimen place at constant temperature on a micro-balance and swept by an inert gas containing a known concentration of VOC); 2) cup method; 3) CLIMPAQ method. The first results obtained by the three different methods show reasonable agreement in the determination of diffusion coefficients. Results for the comparison sorption capacities are not yet available.
