This European Standard specifies the requirements and associated test methods applicable to ductile iron pipes, fittings, accessories and their joints for the construction of drains and sewers outside buildings:
NOTE. In this standard, all pressures are relative pressures, expressed in bars (100 kPa = 1 bar).
- Operating without pressure, or with positive 1 or negative pressure.
- Installed below or above ground.
- For conveyance of surface water, domestic waste water and certain types of industrial effluents,
either in separate systems or in mixed systems.
This standard specifies products for gravity sewerage pipelines, for negative pressure pipelines and for pipelines operating at pressures which do not normally exceed 6 bar. For higher-pressure applications, special pipe thickness may be required by agreement between manufacturer and
purchaser.
This standard specifies requirements for materials, dimensions and tolerances, mechanical properties and standard coatings of ductile iron pipes and fittings. It also gives performance requirements for all components including joints.
This standard covers pipes, fittings and accessories cast by any type of foundry process or manufactured by fabrication of cast components, as well as corresponding joints, of a size range
extending from DN 100 to DN 2000 inclusive.
This standard applies to pipes, fittings and accessories which are:
- manufactured with socketed, flanged or spigot ends for jointing by means of various types of standard; gaskets which are not within the scope of this coated;
- normally delivered externally and internally excluding frost.
- suitable for fluid temperatures up to 50 °C
