ISO 6594:2006 specifies the characteristics of cast iron drainage pipes and fittings used for the installation of discharge pipes for waste and sewage, rain water pipe systems, and ventilation pipe systems. The technical specification is applicable to the range of nominal sizes, DN: 40 - 50 - 70 - 75 - 100 - 125 - 150 - 200 - 250 - 300 - 400 - 500 - 600. In addition, ISO 6594:2006 gives the dimensions for the most commonly used pipe and fitting sizes. It also provides control testing and test methods for checking compliance with the technical specification and the dimensional and other requirements.
