Volatile organic compounds (VOC) are an increasing concern in contamination-sensitive manufacturing sites. For the assessment and classification of VOC emissions from building products, a standardized fast screening procedure for classifying materials regarding VOC outgassing is developed to permit specific reduction of indoor airborne molecular contamination. It describes sample preparation and storage prior sampling followed by micro-chamber sampling and analysis via thermodesorption coupled with gas chromatography and mass spectrometry (TD-GC/MS). Knowing the active surface area, sampling time and emitted VOC mass measured, the material specific surface emission rate SERa and classification number can be determined. The standardized method allows a faster material screening compared to existing large chamber measurement methods. Material screening results are entered into the database www.ipa-csm.com to allow the tested products to be directly compared with one another. Therefore, a material selection already in the planning phase of a controlled environment becomes possible. Based on SERa values, an experimental proven simulation model enables the calculation of the expected ISO-AMC-class of the controlled environment to be constructed according to ISO 14644-8.
