Internal protection by polymeric lining for ductile iron pipes — Requirements and test methods — Part 4: Ceramic epoxy lining

This international specification outlines the technical requirements and corresponding test methods for ceramic epoxy linings applied to the interior surfaces of ductile iron pipes. Designed to enhance corrosion resistance and extend service life, the document details the specific material properties, application procedures, and performance criteria necessary for successful implementation. The scope covers the evaluation of adhesion strength, thermal stability, and chemical resistance under defined operational conditions. It establishes a unified framework for assessing the quality of the polymer-based ceramic coating system, ensuring consistency across manufacturing and installation processes. The text specifies the methodologies for conducting laboratory tests to verify compliance with the stipulated technical parameters, including surface preparation, curing conditions, and final inspection protocols. By providing a standardized approach to quality control, the document facilitates reliable procurement and installation of protected pipeline systems in various industrial and municipal applications. The focus remains strictly on the technical aspects of the lining materials and the validation of their protective capabilities without addressing broader market implications.
