The paper discusses an interlaboratory comparison of three materials to assess the agreement among laboratories for characterizing volatile organic compounds emitted from indoor materials and products using small test chambers. Results from the 20 participating laboratories showed that chambers of different materials (glass and stainless steel) and of widely different capacities (0.035 to 1475 liters) appeared equally suitable. The repeatability of duplicate measurements (including sampling) within each laboratory was good. The test with a known n-dodecane source showed, for most laboratories, an unexpected and yet unexplained discrepancies. The interlaboratory agreement appeared reasonable (coefficient of variation 26-42%) with a polyvinyl chloride tile; but with a wax, the scatter was very high.
