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.

This document specifies materials and the general aspects of polyethylene (PE) pressure piping systems (mains and service pipes) for buried or above ground applications, intended for the conveyance of:

water intended for human consumption,

raw water prior to treatment,

drains and sewers under pressure,

vacuum sewer systems,

water for irrigation,

water for other purposes, with the exception of industrial applications.

The intended use includes sea outfalls, laid in water and pipes suspended below bridges.

NOTE 1:

Attention is drawn to Clause 6 of this document for PE components for the conveyance of water intended for human consumption and raw water prior to treatment. Components manufactured for water for other purposes, drains and sewers, and vacuum sewer systems are possibly not suitable for water supply for human consumption.

PE pipe systems for industrial applications and irrigation with limited pressure exposure are not covered by this document.

NOTE 2:

Industrial application is covered by ISO 15494, irrigation with limited pressure exposure is covered by ISO 8779 (Ed3).

This document also specifies the test parameters for the test methods referred to in this document.

In conjunction with ISO/DIS 4427-2, ISO/DIS 4427-3 and ISO/DIS 4427-5, this document is applicable to PE pipes and fittings, their joints and to joints with components made of PE and other materials, intended to be used under the following conditions:

a) a maximum allowable operating pressure (3.3.2) (PFA) up to and including 25 bar;

b) an operating temperature of 20 °C as the reference design temperature (3.3.3).

For applications operating at constant temperatures greater than 20 °C and up to and including 50 °C, see Annex A.

The ISO 4427 series covers a range of maximum allowable operating pressures and gives requirements concerning colours.

It is the responsibility of the purchaser or specifier to make the appropriate selections from these aspects, taking into account their particular requirements and any relevant national guidance or regulations and installation practices or codes.
