31、 (E) 6 Foreword This document (EN 545:2010) 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 European Standard shall be given the status of a national standard, either by publication of an identical text
32、 or by endorsement, at the latest by March 2011, and conflicting national standards shall be withdrawn at the latest by March 2011. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and/or CENELEC shall not be held responsible f
33、or identifying any or all such patent rights. This document supersedes EN 545:2006. In this standard Annex A is normative and Annexes B, C, D, E and F are informative. This standard is in conformity with the general requirements already established by CEN/TC 164 in the field of water supply. In resp
34、ect of potential adverse effects on the quality of water intended for human consumption, caused by the products covered by this standard: this standard provides no information as to whether the products may be used without restriction in any of the member states of the EU or EFTA; it should be noted
35、 that, while awaiting the adoption of verifiable European criteria, existing national regulations concerning the use and/or the characteristics of these products remain in force. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bo
36、und to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain,
37、 Sweden, Switzerland and the United Kingdom. BS EN 545:2010EN 545:2010 (E) 7 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 outside buildings: to convey d
38、ifferent 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 Eu
39、ropean Standard 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
40、regulations. This does not preclude special arrangements for the products to be used at higher temperatures. This European 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 s
41、ize range extending from DN 40 to DN 2 000, inclusive. 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. J
42、oint design and gasket shapes are outside the scope of this standard. 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 European Standard, all pressures are relative
43、 pressures, expressed in bars (100 kPa = 1 bar). 2 Normative references The following referenced documents are indispensable for the application of this document.
