With the countries in the world gradually emphasize that the well-controlled of indoor air quality (IAQ) and indoor environment health (IEH) would reduce the hazards of human health. This study response the international community has been launched sorptive building materials, such as standards ISO, JIS, etc in recent years, and based on ISO 16000-23 through the small-scale chamber equipment system to develop and establish “sorptive building material test system, SBMTS”, National Performance Laboratory Center in Taiwan. In accordance with standard operating procedures (SOP) to validation of the test system and provided for sorption test by three building materials. The results was verified SBMTS to conform concentrations of HCHO recovery more than 80% by repeatedly sampling and the system was meet the stability through the instrument monitoring display, which could to provide the relevant performance validation and testing for SBM. This study according results with sorption test of select foreign and domestic by building materials, and the performance calculation include the sorption flux, Fm and the equivalent ventilation rate, Fv, eq by SBM, which could provide to reference of the national standards.
