It is possible to test the door and window profiles up to 4,5 x 4,5 m, facade or glazed joineries with the German Karls Shulten test machine.
The quality of the products are measured with the resistance tests by exposing the maximum 4,5x4,5 m joinery systems to artificial weather conditions (air, pressure, wind, water). The wind tests are performed under 1000-1200 Pascal force with vacuum, it is able to reach to 3000 Pascal force.
The ready joineries are subjected to certification process being sent to IFT Rosenheim pursuant to the performances obtained as a result of the tests.
