“…However, homogeneous material was often hard to find, and the source strengths of single VOCs were mostly not in a suitable range for a comparison exercise. To fulfill these requirements, BAM started to develop a suitable reference material for the use in test chamber measurements 7‐10 . In the RRTs in 2009, 2014, 2016, and 2018, a lacquer system added with a VOC mixture in suitable amounts was used as test material.…”

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%.

“…4,6,10,13 Experiments were carried out in a standard 203 L emission test chamber and two smaller chambers with volumes of 24 L and 44 mL, respectively, with a spiked reference polyurethane material that contained the 14 substances. The two smaller chambers, widely tested in previous studies, [21][22][23] would accommodate consumer product sizes much better and should also reduce costs and energy consumption. Moreover,…”

Emissions of volatile organic compounds from polymer‐based consumer products: Comparison of three emission chamber sizes

et al. 2019

The ISO 16000 standard series provide guidelines for emission measurements of volatile organic compounds (VOCs) from building materials. However, polymer‐based consumer products such as toys may also release harmful substances into indoor air. In such cases, the existing standard procedures are unsuitable for official control laboratories due to high costs for large emission testing chambers. This paper aims at developing and comparing alternative and more competitive methods for the emission testing of consumer products. The influence of the emission chamber size was investigated as smaller chambers are more suited to the common size of consumer products and may help to reduce the costs of testing. Comparison of the performance of a 203 L emission test chamber with two smaller chambers with the capacity of 24 L and 44 mL, respectively, was carried out by using a polyurethane reference material spiked with 14 VOCs during the course of 28 days. The area‐specific emission rates obtained in the small chambers were always similar to those of the 203 L reference chamber after a few hours. This implies that smaller chambers can provide at least useful numbers on the extent of polymer‐based consumer product emissions into indoor air, thereby supporting meaningful exposure assessments.
