DIN Standards Committee Materials Testing

Overview

This European Standard specifies the requirements and associated test methods applicable to ductile iron pipes, fittings, accessories and their joints for the construction of pipelines outside buildings. This standard 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, inclusively. This European 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. Joint design and gasket shapes are outside the scope of this European Standard. In addition, reference is made to the performance requirements of couplings, flange adaptors and saddles manufactured for use with ductile iron pipes and fittings. The new edition has been published due to a correction of the standardized length for DN 900 and DN 1400 in Table 4 of the German-language version. This standard (EN 545:2010) has been prepared by Technical Committee CEN/TC 203 "Cast iron pipes, fittings and their joints" (secretariat: AFNOR), with German collaboration. Regarding the German collaboration, the responsible Working Committee is NA 082-00-05 AA "Gusseiserne Rohre und Formstücke" ("Cast iron pipes and fittings") of the Piping and Boiler Plant Standards Committee (NARD).
