Edition date: 2026-05-20
In Force
Available languages: English, French
Summary: This document specifies definitions and requirements for solid-wall pipes with or without internal skin and smooth internal and external surfaces extruded from the same compound throughout the wall, fittings and the system of polyethylene (PE) piping systems to be intended for use in non-pressure underground drains and sewers for wastewater. NOTE 1 Products complying with this document can also be used in non-pressure underground drains and sewers for surface water. This document is applicable to: a) non-pressure drains and sewers, which are intended to be used buried underground outside the building structure, reflected in the marking of products by “U”; b) non-pressure drains and sewers, which are intended to be used buried underground both outside (application area code “U”) and within the building structure, reflected in the marking of products by “UD”. This document specifies test methods referred to in this document and test parameters. This document is applicable to pipes and fittings with or without an integral socket. This document covers a range of pipe and fitting sizes, stiffness classes, tolerance classes and gives recommendations concerning colours. NOTE 2 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. In conjunction with CEN/TS 12666-2 [1] it is applicable to PE pipes and fittings, their joints and to joints with components of other plastics and non-plastics materials intended to be used for buried piping systems for non-pressure drains and sewers. The fittings can be manufactured by injection moulding or can be fabricated from pipes and/or mouldings. This document is applicable to PE pipes and fittings for the following types of joints: — elastomeric ring seal joints; — butt fused joints; — electrofusion joints; — mechanical joints. NOTE 3 Pipes, fittings and other components conforming to any of the plastics product standards listed in the Annex C (informative) can be used with pipes and fittings conforming to this document, provided they conform to the requirements for joint dimensions given in Clause 7 and to the requirements of Clause 7 and Table 13.

ANMERKUNG 1 Produkte, die diesem Dokument entsprechen, können auch in drucklosen erdverlegten Abwasserkanälen und leitungen für Niederschlagswasser verwendet werden. Dieses Dokument ist anwendbar für: a) drucklose Abwasserkanäle und -leitungen, die für erdverlegte Anwendungen außerhalb einer Gebäudestruktur vorgesehen sind; angezeigt durch Kennzeichnung der Erzeugnisse mit „U“; b) drucklose Abwasserkanäle und leitungen, die sowohl für erdverlegte Anwendungen außerhalb der Gebäudestruktur (Anwendungskennzeichen „U“) als auch innerhalb einer Gebäudestruktur vorgesehen sind; angezeigt durch Kennzeichnung der Erzeugnisse mit „UD“. Dieses Dokument legt Prüfverfahren, auf die in diesem Dokument Bezug genommen wird, sowie Prüfparameter fest. Dieses Dokument ist anwendbar auf Rohre und Formstücke sowohl mit glatten Enden als auch mit angeformter Muffe. Dieses Dokument behandelt Steifigkeitsklassen für verschiedene Maße von Rohren und Formstücken, sowie Toleranzklassen und gibt Empfehlungen für die Einfärbung. ANMERKUNG 2 Der Anwender bzw. Auftraggeber ist unter Berücksichtigung der eigenen Anforderungen sowie der geltenden nationalen Empfehlungen oder Festlegungen und Verlegepraktiken oder vorschriften für die entsprechende Auswahl dieser Kriterien verantwortlich. Zusammen mit CEN/TS 12666 2 [1] ist dieses Dokument anwendbar für Rohre und Formstücke aus PE, ihre Verbindungen untereinander sowie mit Rohrleitungsteilen aus anderen Kunststoffen oder Rohrwerkstoffen, die für erdverlegte drucklose Abwasserkanäle und leitungen vorgesehen sind. Die Formstücke können im Spritzgießverfahren oder handgefertigt aus Rohren und/oder Spritzgussteilen hergestellt sein. Dieses Dokument ist anwendbar für Rohre und Formstücke aus PE mit folgenden Verbindungsarten:  elastomere Dichtringverbindungen;  Heizelementstumpfschweißverbindung;  Heizwendelschweißverbindung (Heizwendelschweißmuffe);  mechanische Verbindungen. ANMERKUNG 3 Rohre, Formstücke oder andere Rohrleitungsteile, die einer der in Anhang D (informativ) aufgeführten Anwendungsnormen für Kunststofferzeugnisse entsprechen, können mit Rohren und Formstücken nach diesem Dokument verwendet werden, sofern sie die Anforderungen an die Maße der Verbindungen nach Abschnitt 7 sowie die Anforderungen nach Abschnitt 7 und Tabelle 13 erfüllen.

Le présent document spécifie les définitions et les exigences pour les tubes à paroi compacte avec ou sans peau interne, avec des surfaces internes et externes lisses, extrudés à partir de la même composition à travers la paroi, pour les raccords et le système de canalisations en polyéthylène (PE) destinés à être utilisés pour des branchements et des collecteurs d’assainissement enterrés sans pression pour les eaux usées. NOTE 1 Les produits conformes au présent document peuvent également être utilisés dans des branchements et des collecteurs d’assainissement enterrés sans pression pour les eaux de surface. Le présent document s’applique : a) aux branchements et collecteurs d’assainissement sans pression, destinés à être utilisés enterrés à l’extérieur de la structure des bâtiments, repérés au niveau du marquage des produits par la lettre « U » ; et b) aux branchements et collecteurs d’assainissement sans pression, destinés à être utilisés enterrés, aussi bien à l’extérieur (code de la zone d’application « U ») qu’à l’intérieur de la structure des bâtiments, repérés au niveau du marquage des produits par les lettres « UD ». Le présent document spécifie les méthodes d’essai auxquelles il est fait référence dans le présent document et les paramètres d’essai. Le présent document est applicable aux tubes et raccords avec ou sans emboîture intégrée. Le présent document couvre une gamme de dimensions de tubes et de raccords, de classes de rigidité et de classes de tolérance, et donne des recommandations concernant les couleurs. NOTE 2 Il est de la responsabilité de l’acheteur ou du concepteur du réseau d’effectuer les choix appropriés à partir de ces données, en tenant compte des exigences particulières et de toute réglementation nationale applicable, ainsi que des pratiques ou codes de pose. Conjointement avec la CEN/TS 12666-2[1], ce document s’applique aux tubes et aux raccords en PE, à leurs assemblages et aux assemblages avec des composants en d’autres matières plastiques ou non plastiques, destinés à être utilisés pour les systèmes de canalisations enterrés pour branchements et collecteurs d'assainissement sans pression. Les raccords peuvent être fabriqués par moulage par injection ou être façonnés à partir de tubes et/ou de pièces moulées. Le présent document s’applique aux tubes et raccords en PE pour les types d’assemblages suivants : — assemblages à bague d’étanchéité en élastomère ; — assemblages soudés bout à bout ; — assemblages par électrosoudage ; — assemblages mécaniques.
