BS EN 598:2007 pdf free.Ductile iron pipes,fittings, accessoriesand their joints forsewerage applications—Requirements andtest methods.
BS EN 598 This European Standard specifies the requirements and associated test methods applicable to ductle iron pipes.fittings, accessories and their joints for the construction of drains and sewers outside buildings:
– operating without pressure (gravity sewerage), or with positive or negative pressure (see Table 5);
-to be installed below or above ground;
-to convey surface water, domestic waste water and certain types of industrial effluents, either in separate systems or in combined systems.
This European Standard applies to pipes, fittings and accessories which are:
-manufactured with socketed, flanged or spigot ends;
-normally delivered externally and internally coated;
suitable for continuous fluid temperatures between 0 C excluding frost, and 45 °C for DN s 200 or 35 °C forDN >200, according to EN 476;
-not intended for use in areas subject to reaction to fire regulations.
NOTE1 This does not preclude special arrangements for the products to be used at higher temperatures.
This European Standard covers pipes fittings and accessories cast by any type of foundry process or manufacturedby fabrication of cast components, as well as corresponding joints, of a size range extending from DN 80 to DN 2000inclusive.
This European Standard specifies requirements for materials, dimensions and tolerances,mechanical properties andstandard coatings of ductile iron pipes and fittings. It also gives performance requirements for all componentsincluding joints.Joint design and gasket shapes are outside the scope of this European Standard.
NOTE 2 In this European Standard, all pressures are relative pressures, expressed in bars (100 kPa = 1 bar).
