In parallel to the outdoor exposure tests, the materials were exposed in climate chambers to articifially produced environmental conditions. Here, the researchers investigated different stresses like humidity, salt spray, sand erosion, UV-Radiation or thermal cycling and selected an appropriate testing sequence to reproduce the observed degradation mechanisms from outdoors in a realistic manner within a short time period in the laboratory.
