2. Standardization of ductile iron pipe systems

2.1 Importance of standards for water systems

Ductile cast-iron pipe systems are part of water networks that are constantly evolving and developing in terms of geographical extension. These networks may mix products from different origins (geographical, manufacturing technique, manufacturer, product generations, materials other than cast iron). It is therefore essential to ensure dimensional, performance and functional compatibility between these components. In particular, standards provide a common language for all players (manufacturers, installers, project managers, contracting authorities, operators, certifiers, etc.) involved in the creation and maintenance of networks.

To achieve these objectives, ductile cast iron pipe systems are covered by a range...
