21、eld by NEN. 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of an identical text or by endorsement, at the latest by November 2007, and conflicting national standards shall be withdrawn at the latest by November 2007. This standard is a part of a System
22、 Standard for plastics piping systems of particular materials for specified applications. There are a number of such System Standards. System Standards are based on the results of the work being undertaken in ISO/TC 138 “Plastics pipes, fittings and valves for the transport of fluids”, which is a Te
23、chnical Committee of the International Organization for Standardization (ISO). They are supported by separate standards on test methods to which references are made throughout the System Standard. The System Standards are consistent with general standards on functional requirements and on recommende
24、d practice for installation. EN 13476 consists of the following Parts under the general title Plastics piping systems for non-pressure underground drainage and sewerage Structured-wall piping systems of unplasticized poly(vinyl chloride) (PVC-U), polypropylene (PP) and polyethylene (PE): Part 1: Gen
25、eral requirements and performance characteristics (this standard); Part 2: Specifications for pipes and fittings with smooth internal and external surface and the system, Type A; Part 3: Specifications for pipes and fittings with smooth internal and profiled external surface and the system, Type B;
26、Part 4: Assessment of conformity (CEN/TS); Part 5: Guidance for installation (CEN/TS).1For pipes and fittings which have conformed to the relevant national standard before May 2007, as shown by the manufacturer or by a certification body, the national standard may continue to be applied until May 20
27、09. National standards specifically for pipes and fittings for the transport of surface water are not considered to be conflicting with this standard and may thus be allowed to coexist. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries
28、 are bound to implement this European Standard: 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, S
29、weden, Switzerland and United Kingdom. 1The feasibility of this project is under study. EN 13476-1:2007 (E) 5 Introduction Due to the variety in materials, pipe constructions, application areas and classes, several combinations are possible. The purchaser or specifier may select between these possib
30、ilities by designating the pipe and fitting he or she prefers to use for each case, as described in Annex C, Designation of pipes and corresponding fittings, taking into account any particular requirements and relevant national regulations and installation practices or codes. EN 13476-1:2007 (E) 6 1
31、 Scope This European Standard, together with EN 13476-2 and EN 13476-3, specifies the definitions and general requirements for pipes, fittings and the system based on unplasticized poly(vinyl chloride) (PVC-U), polypropylene (PP) and polyethylene (PE) structured-wall piping systems that are to be us
32、ed for non-pressure underground drainage and sewerage systems. This standard is applicable to: a) structured-wall pipes and fittings, which are to be used buried in the ground outside a building structure only; reflected by the marking of products by “U”; b) structured-wall pipes and fittings, which
33、 are to be used buried in ground both outside (application area code “U”) and within a building structure (application area code “D”); reflected in the marking of products by “UD”. In conjunction with EN 13476-2 and EN 13476-3 it is applicable to structured-wall pipes and fittings with or without an
34、 integral socket with elastomeric ring seal joints, as well as welded and fused joints. This part specifies general aspects and gives guidance concerning a national selection of requirement levels and classes where part 2 and part 3 of this standard provide options. EN 13476-2 and EN 13476-3 specify
35、 material characteristics, dimensions and tolerances, test methods, test parameters and requirements for pipes with smooth internal and external surfaces, Type A, and pipes with smooth internal and profiled external surfaces, Type B. This standard, together with EN 13476-2 and EN 13476-3, covers a r
36、ange of pipe and fitting sizes, materials, pipe constructions, stiffness classes and tolerance classes and offers recommendations concerning colours. NOTE 1 It is the responsibility of the purchaser or specifier to make the appropriate selections from these aspects, taking into account their particu
37、lar requirements and any relevant national regulations and installation practices or codes. NOTE 2 Pipes, fittings and other components conforming to any plastic product standards referred to in clause 2 can be used with pipes and fittings conforming to this standard, when they conform to the requir
38、ements for joint dimensions given in part 2 and part 3 of this standard and to the performance requirements given in Clause 9. NOTE 3 For dimensions larger than DN 1200 OD/ID this document may serve as general guideline regarding appearance, colour, physical and mechanical characteristics as well as
39、 performance requirements. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies.
