Abstract
In such fields as cleanroom technology, food, pharmaceutics and health care as well as in normal living and working environments, materials implemented in specific applications need to be assessed for VOC emissions and classified in order to permit direct comparisons to be made. The paper presents a standardized procedure for testing and classifying materials with uniform sample preparation and defined storage times. It describes preparation of the samples, their measurement in a VOC-free minienvironment, avoidance of cross-contamination, sampling using appropriate adsorbents in micro-chambers and analysis via thermodesorption coupled with chromatography and mass spectrometry (TD-GC/MS). Once the active surface, sampling time and VOC mass emitted are known, a specific emission rate can be determined which is then converted into a classification using a calculation model. Knowledge of the emission class enables the VOC charge of a defined area at a specific point in time to be calculated in reality. The standardized procedure is laid down in the guideline VDI 2083 Part 17 which will be published at the end of 2010. The tests and classifications are carried out by the Fraunhofer IPA and the resulting product classifications are then entered into the CSM database www.ipa-csm.com of the industrial alliance CSM -cleanroom suitable materials for exclusive use by alliance members to allow the tested products to be directly compared with one another.
