The 16th Wiesbadener Kunststoffrohrtage (Wiesbaden Plastic Pipe Days), held in 2012, served as an international forum for polymer-based piping systems. This was the second time TÜV SÜD organized the event, which highlighted the latest trends and innovations in the plastics industry. A key presentation was given by Dipl.-Ing. J. Grieser, focusing on the development of acceptance criteria for defects in welded joints.

Additionally, the TestPEP project was introduced, a European-funded initiative aimed at developing automated non-destructive testing (NDE) methods for welded plastic pipe joints. This project received funding from the European Community's Seventh Framework Programme, managed by the REA - Research Executive Agency (FP7-SME-2008-2), under Grant Agreement No. 243791.
