31、epared 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 or by endorsement, at the latest by December 2009, and
32、 conflicting national standards shall be withdrawn at the latest by December 2009. This document includes Amendment 1, approved by CEN on 2009-05-23. This document supersedes !EN 598:2007“. The start and finish of text introduced or altered by amendment is indicated in the text by tags !“. This docu
33、ment has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of EU Construction Products Directive (89/106/EEC). For relationship with EU Construction Products Directive, see informative Annex ZA, which is
34、 an integral part of this document. This European Standard is in conformity with the general requirements already established by CEN/TC 165 in the field of sewerage. Annex ZA includes the requirements of the mandate given under the EU Construction Products Directive (89/106/EEC). Only if the require
35、ments specified in Annex ZA are met, the CE marking will be effected. For reasons of conformity with mandate M/131 “Pipes, tanks and ancillaries not in contact with water intended for human consumption”, EN 598:1994 has been revised by extension with Annex ZA (see Resolution CEN/BT 113/1994 and CEN/
36、BT 63/1996) and Clause 9 for the evaluation of conformity. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Cyprus, Czech Republic, Denmark, Estonia, Finland,
37、France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and United Kingdom. DIN EN 598:2009-10 EN 598:2007+A1:2009 (E) 6 1 Scope This European Standard specifies th
38、e requirements and associated test methods applicable to ductile 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 o
39、r 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 delive
40、red externally and internally coated; suitable for continuous fluid temperatures between 0 C excluding frost, and 45 C for DN 200 or 35 C for DN 200, according to EN 476; not intended for use in areas subject to reaction to fire regulations. NOTE 1 This does not preclude special arrangements for the
41、 products to be used at higher temperatures. This European 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, of a size range extending from DN 80 to DN 2000 inclusive. This European
42、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
43、Standard. NOTE 2 In this European Standard, all pressures are relative pressures, expressed in bars (100 kPa = 1 bar). 2 Normative references The following referenced documents are indispensable for the application of this document.
