International comparison experiment on the determination of VOCs emitted from indoor materials using small test chambersFunded under: JRC-ENVPROT 5C
An interlaboratory comparison of three materials was conducted in order to assess the agreement among laboratories for characterising volatile organic compounds (VOCs) emitted from indoor materials and products using small test chambers. Results from the twenty participating laboratories showed that chambers of different materials (glass and stainless steel) and of widely different capacity (0.035 to 1475 l) appeared equally suitable. The reproducibility 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 as yet unexplained discrepancy. The interlaboratory agreement appeared reasonable (coefficient of variation 26-42 %) with a PVC tile, but with a wax the scatter was very high.
