22、lastics piping systems and ducting systems”, the secretariat of which is held 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 wit
23、hdrawn at the latest by November 2007. This standard is a part of a System 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 “Plast
24、ics pipes, fittings and valves for the transport of fluids”, which is a Technical 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 cons
25、istent with general standards on functional requirements and on recommended 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(viny
26、l chloride) (PVC-U), polypropylene (PP) and polyethylene (PE): Part 1: General 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 w
27、ith smooth internal and profiled external surface and the system, Type B; 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 certifi
28、cation body, the national standard may continue to be applied until May 2009. 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 Re
29、gulations, the national standards organizations of the following countries 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, Ne
30、therlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, 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 combination
31、s are possible. The purchaser or specifier may select between these possibilities 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 nationa
32、l regulations and installation practices or codes. EN 13476-1:2007 (E) 6 1 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 (
33、PP) and polyethylene (PE) structured-wall piping systems that are to be used 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 th
34、e marking of products by “U”; b) structured-wall pipes and fittings, which 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
35、 it is applicable to structured-wall pipes and fittings with or without an 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
36、part 3 of this standard provide options. EN 13476-2 and EN 13476-3 specify 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,
37、Type B. This standard, together with EN 13476-2 and EN 13476-3, covers a range 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 ap
38、propriate selections from these aspects, taking into account their particular 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
39、 and fittings conforming to this standard, when they conform to the requirements 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 regard
40、ing appearance, colour, physical and mechanical characteristics as well as performance requirements. 2 Normative references The following referenced documents are indispensable for the application of this document.
