27、09EN 598:2007+A1:2009 (E) 5 Foreword This document (EN 598:2007+A1:2009) 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 pub
28、lication of an identical text or by endorsement, at the latest by December 2009, and conflicting national standards shall be withdrawn at the latest by December 2009.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 te
29、xt introduced or altered by amendment is indicated in the text by tags !“. This document 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 rela
30、tionship with EU Construction Products Directive, see informative Annex ZA, which is 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
31、given under the EU Construction Products Directive (89/106/EEC). Only if the requirements 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
32、has been revised by extension with Annex ZA (see Resolution CEN/BT 113/1994 and CEN/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 Stand
33、ard: Austria, Belgium, Bulgaria, 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, Sweden, Switzerland and United Kingdom.

34、N 598:2007+A1:2009EN 598:2007+A1:2009 (E) 6 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 drains and sewers outside buildings: operating without pressure (gravity
35、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 acc
36、essories 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 200 or 35 C for DN 200, according to EN 476; not intended for use in areas subject to r
37、eaction to fire regulations. NOTE 1 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 manufactured by fabrication of cast components, as well as correspo
38、nding joints, of a size range extending from DN 80 to DN 2000 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 i
39、ncluding 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). 2 Normative references The following referenced documents are indispensable for the applicatio

45、ubstantially in spheroidal form 3.2 pipe casting of uniform bore, straight in axis, having either socket, spigot or flanged ends, except for flanged-socket pieces, flanged-spigot pieces and collars which are classified as fittings 3.3 fitting casting other than a pipe which allows pipeline deviation
46、, change of direction or bore. In addition flanged-socket pieces, flanged-spigot pieces and collars are also classified as fittings 3.4 accessory any casting other than a pipe or fitting which is used in a pipeline, for example: inspection chambers (see 3.5); manholes (see 3.6); glands and bolts for
47、 mechanical flexible joints (sec 3.15); glands, bolts and locking rings for restrained flexible joints (see 3.16); adjustable flanges and flanges to be welded or screwed NOTE Valves of all types are not covered by the term accessory. 3.5 inspection chamber component of a discharge system, of a drain
