Emission testing of volatile organic compounds (VOC) from materials and products is commonly based on emission test chamber measurements. To ensure the comparability of results from different testing laboratories, their measurement performance must be verified. For this purpose, Bundesanstalt für Materialforschung und -prüfung (BAM) organizes an international proficiency test (round robin test, RRT) every two years using well-characterized test materials (one sealant, one furniture board, and four times a lacquer) with defined VOC emissions. The materials fulfilled the requirements of homogeneity, reproducibility, and stability. Altogether, 36 VOCs were included of which 33 gave test chamber air concentrations between 13 and 83 µg/m3. This is the typical concentration range to be expected and to be quantified when performing chamber tests. Three compounds had higher concentrations between 326 and 1105 µg/m3. In this paper, the relative standard deviations (RSD) of BAM round robin tests since 2008 are compared and the improvement of the comparability of the emission chamber testing is shown by the decrease of the mean RSD down to 28% in 2018. In contrast, the first large European interlaboratory comparison in 1999 showed a mean RSD of 51%.

建筑产品中的挥发性有机化合物——2008 年至 2018 年间在排放测试室中进行的六次循环测试的结果

材料和产品中挥发性有机化合物 (VOC) 的排放测试通常基于排放测试室测量。为确保来自不同测试实验室的结果具有可比性,必须验证其测量性能。为此,Bundesanstalt für Materialforschung und -prüfung (BAM) 每两年组织一次国际能力测试(循环测试,RRT),使用具有明确定义的测试材料(一种密封剂、一种家具板和四次漆) VOC 排放。材料满足均匀性、再现性和稳定性的要求。总共包括 36 种 VOC,其中 33 种的测试室空气浓度介于 13 和 83 µg/m 3 之间. 这是在执行腔室测试时预期和量化的典型浓度范围。三种化合物的浓度较高,介于 326 和 1105 µg/m 3 之间。本文比较了 2008 年以来 BAM 循环测试的相对标准偏差 (RSD),2018 年平均 RSD 下降至 28%,表明排放室测试的可比性有所提高。 相比之下, 1999 年第一次大型欧洲实验室间比较显示平均 RSD 为 51%。
