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.
The latest version of the German AgBB evaluation scheme (2015) for construction products includes some VVOC, e.g. formaldehyde, acetaldehyde and acetone. For these VVOC so-called LCI values (lowest concentration of interest) were derived which are used for the calculation of the so-called R-value (risk index, see reference 1 for the calculation). Test chamber measurements of particle boards show that the emissions of VVOC might have significant impact on the R-value and therefore for the health evaluation.
