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.
With a gas mixing system (GMS) developed in our laboratory we created a gas mixture of
four substances. Adsorptive wall materials of four different compositions were exposed to this
gas mixture, consisting of 1-pentanol, hexanal, butyl acetate and n-decane. Aim of this study
was to scrutinize the ability of these samples to reduce the concentration of the supplied gas.
This capacity is expressed in the sorption flux F or area specific adsorption rate respectively.
The test was performed referring to a draft of ISO 16000-24.
