In January 2003, JIS A1901 on "Determination of the emission of volatile organic compounds and aldehydes for building products -Small chamber method" was published. We have proposed and developed a small chamber for determining chemical emission rates from building materials. In this paper, the performance characteristics of small chamber were examined especially background concentration, airtightness and mass transfer coefficient in the chamber. The performance test method was proposed because that was not clearly stated in related standards. The measurement method for mass transfer coefficient by used the filter paper is applicable for the calibration with the measurement for evaporation-controlled materials. Several small chambers have been used to determine chemical emissions for building materials. However, it is difficult to compare with the result from different chambers. In this paper, formaldehyde concentration with two small chambers was discussed by the relation with loading factor (L) and ventilation rate (n). It was observed that it has possibility to compare with the linear of n/L versus 1/C with used the equilibrium concentration for the segment.
