AWWA Manual on Ductile Iron Pipe and Fittings
DIPRA representatives sit on the defining standards committees of the AWWA, ASME, ASTM, NACE, NFPA, and ISO organizations, ensuring that design and manufacturing standards for Ductile Iron pipe remain the most stringent and comprehensive in the industry.
Suggested Sample Specification for Ductile Iron Pipe & Fittings for Water and Other Liquids (1 Page Handout): This one page downloadable PDF file outlines a sample specification for Ductile Iron pipe and fittings. The conservative and comprehensive nature of the standards for Ductile Iron pipe, covering topics such as manufacturing, design, joints, fittings, and installation, make this simple approach possible.
The following standards are available from the American Water Works Association:
