To give proper recommendations in selection of suitable construction materials for museums, we have recently started an inventory of products available on Swedish market. From these, ten products have been chosen. The selection is based on details such as production procedures, constitution and origin of raw materials, availability on market, construction properties etc. One board of each product, separately handled and sealed in a steady package during transport, will be ordered from the manufactures. The VOC emissions and their emission rate will be determined in chamber experiments in co-operation with the Swedish Institute of Wood Technology Research (Traetek) with the supply of gas samplers for small carbonyl compounds from the Swedish Environmental Research Institute (IVL). In parallel, the traditional material tests with metal coupons will be accomplished at the same conditions (23°C and RH 50%) to evaluate the emissions impact on copper, lead, silver, and zinc. The formed corrosion is evaluated by mass change in accordance to the method developed by the Swedish Corrosion Institute. In this way we intend to correlate determined emissions to the effects. With this knowledge we also intend to shorten the time needed for material tests with metal coupons in a controlled way, for a faster examination process in future.
