CE identification code
The CE mark officially authorizes the Europe-wide marketing of windows and outside doors. Subject to the specifications of national restrictions and special features, the CE template controls, among other things, the generation of test specimens in setting up production series. The design engineer of windows or outside doors is obliged to submit the preassembled product for Initial Type Testing and checking by an accredited agency, according to the performance characteristics prescribed by DIN EN 14351. The resulting report of the Initial Type Test (ITT) is then made available to the actual construction erector, i.e. whoever finally brings the finished product onto the market, on the basis of the hierarchical classification.
