The conversion of steady-state formaldehyde test chamber concentrations to different climatic conditions

The monitoring of the formaldehyde emission potential of wood-based materials by means of test chamber investigations has made an important contribution to significantly reducing the formaldehyde concentrations indoors. Formaldehyde emissions from wood-based materials are complex from both a reaction-kinetic and dynamic perspective. There is an exponential dependence of the emission on temperature and humidity and an inverse proportionality to the air change rate. The mathematical analysis requires sophisticated regression tools. From a statistical point of view there was a very good agreement between experimental data and an empirical model for a wide range of chamber settings. However, the model is not suitable for predicting the emission behavior of individual products.
