Besides measurement of VOC emissions also the evaluation of odour emissions and the perceived intensity of odours gains in importance. Due to difficulties detected in the measurement method of the perceived intensity described in (ISO 16000-28, 2012) the introduction of “reference” odours will be recommended for the training of panellists and as basis for interlaboratory comparisons.
In order to generate the “reference” odours standard liquid substances were directly injected into the main gas flow provided to the panellists. One of the substances tested was ethyl acetate. A pre-evaluation was conducted with six untrained panellists and has shown that ethyl acetate is potentially suitable as reference odour. For further validation of those “reference” odours they additionally will be provided to and evaluated by trained panellists of well established-measurement institutes.
Most VVOC were rarely considered in the evaluation of construction products. (Salthammer, 2014) In Germany this will change because the latest version of the German AgBB scheme for health evaluation (2015) now include VVOC, e.g. ethyl acetate and ethanol. In this study selected compounds were tested with the procedure described in ISO 16017 and a method for measuring VVOC with thermal desorption was developed.
Three different adsorbents Tenax TA, Carbograph 5TD and Carbopack X were tested to analyse VVOC according to ISO 16017. For the tested VVOC, Carbograph 5TD showed the best results under the chosen analytical conditions.
