Foreword
This document (EN 545:2002) has been prepared by Technical Committee CEN/TC 203, "Cast iron pipes, fittings
and their joints", the secretariat of which is held by AFNOR.
This document supersedes EN 545:1994.
This European Standard shall be given the status of a national standard, either by publication of an identical text or
by endorsement, at the latest by December 2002, and conflicting national standards shall be withdrawn at the latest
by December 2002.
In this standard the Annex A is normative and the Annexes B, C, D, E, F and G are informative.
According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following
countries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland,
France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Malta, Netherlands, Norway, Portugal, Spain,
Sweden, Switzerland and the United Kingdom.
Introduction
This standard is in conformity with the general requirements already established by CEN/TC 164 in the field of
water supply.
In respect of potential adverse effects on the quality of water intended for human consumption, caused by the
product covered by this standard :

this standard provides no information as to whether the product may be used without restriction in any of the
member states of the EU or EFTA ;

it should be noted that, while awaiting the adoption of verifiable European criteria, existing national regulations
concerning the use and/or the characteristics of this product remain in force.
1 Scope
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 :

to convey water (e. g. potable water) ;

with or without pressure ;

to be installed below or above ground.
This standard is applicable to pipes, fittings and accessories which are :

manufactured with socketed, flanged or spigot ends;

normally delivered externally and internally coated ;

suitable for fluid temperatures between 0 °C and 50 °C, excluding frost.
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, in a size range extending from DN 40 to DN 2 000,
inclusive.
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. Joint design and gasket shapes are outside the scope of this standard.
NOTE In this standard, all pressures are relative pressures, expressed in bars (100 kPa = 1 bar).

normative references are cited at the appropriate places in the text and the publications are listed hereafter. For
dated references, subsequent amendments to or revisions of any of these publications apply to this European
Standard only when incorporated in it by amendment or revision. For undated references the latest edition of the
