This document specifies the requirements and associated test methods applicable to ductile iron pipes, fittings, accessories and their joints for the construction of pipelines outside buildings: — to convey different types of water (e.g. raw water, treated water, re-used water) for all types of applications (e.g. water intended for human consumption, for fire protection, for snow making, for irrigation, for hydro-electricity etc.); — with or without pressure; — to be installed below or above ground. This document is applicable to pipes, fittings and accessories which are: — manufactured with socketed, flanged or spigot ends; — supplied externally and internally coated; — suitable for fluid temperatures between 0 °C and 50 °C, excluding frost; — not intended for use in areas subject to reaction to fire regulations. This does not preclude special arrangements for the products to be used at higher temperatures. This document covers pipes and fittings cast by any type of foundry process or manufactured by fabrication of cast components, as well as corresponding joints and accessories, in a size range extending from DN 40 to DN 2 000, inclusive. This document 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. Joint design and gasket shapes are outside the scope of this document. In addition, reference is made to the minimum performance requirements of couplings, flange adaptors and saddles manufactured for use with ductile iron pipes and fittings. NOTE In this document, all pressures are relative pressures, expressed in bars (100 kPa = 1 bar).

This document specifies requirements for the composition of CO2 streams relevant to the integrity of carbon steel pipeline systems, including limits on non-condensable components. It establishes the framework conditions for the supply, transportation and distribution of CO2 streams. Considerations related to the health effects of the CO2 stream (e.g. toxicity), environmental impact, or other properties of impurities are outside the scope of this document.

This document specifies requirements and test methods for joint casing systems for single and twin pipes between adjacent factory-made pipe, and/or fitting and/or valve assemblies for buried heating and cooling water networks with rigid pipe systems with metal service pipes in accordance with EN 13941-1 [4] and EN 13941-2 [5] as well as rigid pipe systems with plastic service pipes according to series EN 17415 and flexible pipe systems with metal service pipes according to EN 15632-4 .

NOTE There are no differences in requirements for single and twin pipe joint casing systems.

For bedding materials other than those defined in 5.2.3 additional precautions are defined inEN 13941-2 [5].
