Doors, separating rooms with different temperatures and humidity, are likely to distort. This is due to swelling and shrinkage of the involved components. 

During the test, after pre-conditioning, the door is exposed to different climates each side, following European Norm DIN EN 1121. The test is continued until deformation and distortion end. This is expected to endure 28 days.
