Standardization of plastic pipes
and molded parts to DIN in Germany





In Germany plastic pipes and molded parts are characterized in an extensive set of standards and rules. Research and continuous development bring about new formulations with enhanced properties for plastics. The standardization must take this development into account and has to be updated constantly on national level and international level as well. In addition there are approved test institutes, representing for the industrial plant construction on national and international level an optimum quality standard due to additional testing and inspecting duties.
