WHAT IS BEHIND TVOC IN Ml -CLASSIFIED CONSTRUCTION AND FINISHING MATERIALS - VTT'S EXPERIENCE

摘要

The Finnish Classification of Indoor Climate, Construction and Finishing Materials was first published in 1995 revised in year 2000 (Classification of Indoor Climate 2000). One part of the requirements consists of Emission Classification of building materials. The aim of establishing the classification is to enhance the development and use of low-emitting building materials. TVOC was chosen as one criterion representing the whole group of VOC-emissions as the emission testing procedure should be simple, well defined for different building material categories, cost effective and fulfill the requirement of pre-defined, short testing time and cost. Up today 500 building materials have been granted Ml label. This study overviews how well the TVOC-concept covers the possible health- and comfort effects of the single VOC-emissions.
