Field testing and natural aging/degradation of test sample, e.g. coated wooden surfaces is a slow process. Accelerated tests focus on mechanical properties, water uptake or sometimes stain fungi. Artificially weathered coated panels are not easily compared with naturally aged panels, and show the importance of involving the biological component among the degrading facors. It is a need for accelerated tests and especially tests that concider the interaction between the property of water uptake, weathering and biological factors. The Mycologg can combine artificial weathering, monitoring of moisture uptake and fungal growth.
