Indoor air pollutants influence the health and comfort of building occupants and consequently the energy consumption of the building. The pollutants are emitted by various sources.
Among these sources, building products are of particular importance. To control the emission of pollutants from building materials, a few different voluntary labelling Systems have been introduced in Europe. In Germany also mandatory “Principles for the health assessment of construction products used in interiors” have been applied for the technical approval of floor coverings since 2004. This procedure is based on the assessment scheine of the Committee for Health-related
Evaluation of Building Products (AgBBScheme). The sensory-limit settings for building-material label Blue Angel offer consumer to differ not only low-emission but also low-odour Building materials from another building materials.
This study investigated the adaptation of the state-of-the-art test procedure for the determination of emissions of volatile organic compounds (VOC) from materials into indoor air to test for the radon exhalation from stony construction products. A complete robustness validation including all relevant parameters showed that the procedure can be well applied by testing institutes already holding available the required VOC testing infrastructure that solely needs to be complemented by calibrated commercial radon measurement instrumentation. When measurements of the radon exhalation from construction materials become mandatory by law, test capacity can easily be applied. This work can serve as a recommendation for the European standardisation that still is on hold in this point.
