Trust us and our experience

TZWL can look back on more than twenty years of testing activity in carrying out 200 approval tests to obtain type approval (Ü mark) from the German Institute for Building Technology (DIBt) in Berlin. Of particular note here is the performance of tests for technically complex system constellations, which are frequently carried out at TZWL.

The process of obtaining type approval (Ü mark) is demanding. With its many years of experience, TZWL is on hand to advise you on the tests to be carried out. We will familiarize you with the details and time requirements and ensure that the approval process runs as smoothly as possible.
