25、45 Additional guidance for UK usersEN 13476-2:2007 (E) 4 Foreword This document (EN 13476-2:2007) has been prepared by Technical Committee CEN/TC 155 “Plastics piping systems and ducting systems”, the secretariat of which is held by NEN. This European Standard shall be given the status of a national
26、 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of an identical text or by endorsement, at the latest by November 2007, and conflicting national standards shall be withdrawn at the latest by November 2007.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 Standard for plastics piping systems of particular materials for a specif
27、ied application. 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 Technical Committee of the International Organization for Standardization (
28、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 recommended practice for installation. EN 13476 consists of the following Parts und
29、er 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: General requirements and performance characteristics; Part 2: Specifications
30、for pipes and fittings with smooth internal and external surface and the system, Type A (this standard); Part 3: Specifications for pipes and fittings with a smooth internal surface and profiled external surface and the system, Type B; Part 4: Assessment of conformity (CEN/TS); Part 5: Guidance for
31、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 2009. National standards specifically for pipes and fittings for t
32、he 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 are bound to implement this European Standard: Austria, Belgium
33、, 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. 1The feasibility of this
34、project is under study. EN 13476-2:2007 (E) 5 Introduction This standard provides optional choices for impact resistance (see Annex G and Annex H) and ring flexibility, see Annex I. As appropriate, the individual countries may select between those options in their national forewords. EN 13476-2:2007
35、 (E) 6 1 Scope This part of EN 13476, together with EN 13476-1, specifies the definitions and 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 intended to be used for
36、non-pressure underground drainage and sewerage systems. This part is applicable to pipes and fittings with smooth internal and external surfaces, designated as Type A. It specifies test methods and test parameters as well as requirements. This part is applicable to: a) structured-wall pipes and fitt
37、ings, which are intended to be used buried underground outside the building structure; reflected in the marking of products by “U”; b) structured-wall pipes and fittings, which are intended to be used buried underground both outside (application area code “U”) and within the building structure (appl
38、ication area code “D”); reflected in the marking of products by “UD”. This part 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 covers a range of pipe and fitting sizes, materials,
39、pipe constructions, stiffness classes, application classes, and tolerance classes and gives 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 particular requirements and a
40、ny relevant national regulations and installation practices or codes. NOTE 2 For dimensions larger than DN 1200 OD/ID this document may be applied regarding appearance, colour, physical and mechanical characteristics as well as performance requirements. 2 Normative references The following reference
