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. Summary standardization plastic pipes and molded parts

Plastic pipes and molded parts are nationally structured according to dimensions and quality requirements. The chart below gives an overview and detailed information about the standardization of the most important pipe materials.
