Different testing standards lead to different emission values for the materials. Such standards are compared in this study. Besides scenarios with varying loading factors, air exchange rates and climatic conditions were investigated to evaluate the formaldehyde emission potential of different building products. Under realistic indoor conditions used for the emission chamber tests, exceeding of formaldehyde indoor guide values were obtained. Results showed the need for improvement of wood-based materials with lower formaldehyde emissions and the adaption of testing parameters closer to realistic conditions.

Foam tiles made from melamine resins are often used for acoustic insulation because they show good fire resistance and good thermal insulation properties. But they can emit formaldehyde. In Germany there are cases with a resulting indoor air concentration of higher than 100 µg/m³. In this study samples from two schools and one office were investigated. Additionally, new tiles were purchased and tested to evaluate the general potential as formaldehyde source.

A1 - Wilke, Olaf A1 - Jann, Oliver T1 - Application of a novel reference material in an international round robin test on material emissions testing JF - Indoor Air N2 - Emission testing of products is currently a rapidly increasing field of measurement activity. Labelling procedures for construction products are based on such emission test chamber measurements and hence measurement performance should be verified. A suited procedure for this purpose is the testing of one unique homogenous material in different laboratories within a Round Robin Test (RRT). Therefore, it is useful to have a reference material which can be used within inter-laboratory studies or as part of the quality management system to ensure comparable results. Several approaches on the development of reproducibly emitting materials have been published. These have in common only to emit a single VOC – toluene. Two further research studies carried out by BAM aimed to develop reference material for emissions testing containing one or more VOC in a single material. The first approach was a doped lacquer with Volatile and Semi-Volatile Organic Compounds (VOC/SVOC) and the second was Thermoplastic Polyurethane (TPU) or a Squalane/Paraffin mixture. Results received with the lacquer based material were presented in more detail.
