With a state-of-the-art climate chamber, the application technology can generate various climatic conditions. Whether a hot-dry summer day or a wet-cold winter day, the climate chamber can be set to different temperatures, humidity and cycles. Depending on the material category and sample size, the customer can specify how the test should be implemented. The substrates specified in the order and the products to be tested are preconditioned under the desired climatic conditions for at least 24 hours. The samples are then prepared according to the customer's order and, depending on the requirements, stored under the climatic conditions until the final hardening or for further testing. It is also possible to carry out product comparisons with large moveable walls in the climate chamber.
