EN 13476-2:2018 (E) 5 This standard is a part of a System Standard for plastics piping systems of particular materials for a specified 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 (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 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: General requirements and performance characteristics; — Part 2: Specifications 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). (CEN/TS 13476-4:2013; valid for pipes up to and incl.to DN 1200). For guidance for installation, see CEN/TR 1046. 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 are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom. SIST EN 13476-2:2018
EN 13476-2:2018 (E) 6 Introduction This standard provides optional choices for impact resistance (see Annex G, Annex H and Annex K) and ring flexibility, see Annex I. As appropriate, the individual countries may select between those options in their national forewords. SIST EN 13476-2:2018
EN 13476-2:2018 (E) 7 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 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 fittings, 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 (application 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, pipe constructions, stiffness classes, application classes, and tolerance classes and gives recommendations concerning colours. NOTE It is the responsibility of the purchaser or specifier to make the appropriate selections from these aspects, taking into account their particular requirements and any relevant national regulations and installation practices or codes. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
