Plastics piping systems for the supply of gaseous fuels - Polyethylene (PE) - Part 2: Pipes
This document specifies the characteristics of pipes made from polyethylene (PE) for piping systems in the field of the supply of gaseous fuels.
It also specifies the test parameters for the test methods referred to in this document.
In conjunction with Parts 1 and 3 to 5 of EN 1555, it is applicable to PE pipes, their joints and to joints with components of PE and other materials intended to be used under the following conditions:
a) a maximum operating pressure, MOP, up to and including 10 bar1at a reference temperature of 20 °C for design purposes;
b) an operating temperature between −20 °C and 40 °C.
NOTE 1 For operating temperatures between 20 °C and 40 °C derating coefficients are defined in EN 1555-5:2021.
EN 1555 covers a range of maximum operating pressures and gives requirements concerning colours.
It covers three types of pipe:
— PE pipes (outside diameter dn) including any identification stripes;
— PE pipes with co-extruded layers on either or both the outside and/or inside of the pipe (total outside diameter dn) as specified in Annex A, where all layers have the same MRS rating. A coextruded pipe made of a combination of PE 100 and PE 100-RC layers shall be regarded as PE 100 and marked accordingly;
— PE pipes (outside diameter dn) with a peelable, contiguous thermoplastics additional layer on the outside of the pipe (‘coated pipe’) as specified in Annex B.
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.
Kunststoff-Rohrleitungssysteme für die Gasversorgung - Polyethylen (PE) - Teil 2: Rohre
Dieses Dokument legt die Eigenschaften von Rohren aus Polyethylen (PE) für Rohrleitungssysteme im Bereich der Versorgung mit gasförmigen Brennstoffen fest.
Es legt auch die Prüfparameter für die Prüfverfahren fest, auf die in diesem Dokument verwiesen wird.
In Verbindung mit Teil 1 und Teil 3 bis Teil 5 von EN 1555 gilt es für Rohre aus PE, deren Verbindungen untereinander sowie mit Rohrleitungsteilen aus PE und anderen Werkstoffen, die für die Verwendung unter den folgenden Bedingungen vorgesehen sind:
a) für einen maximal zulässigen Betriebsdruck MOP (en: maximum operating pressure) von höchstens 10 bar1 bei einer Bezugstemperatur von 20 °C für Bemessungszwecke;
b) für eine Betriebstemperatur zwischen −20 °C und 40 °C.
ANMERKUNG 1 Für Betriebstemperaturen zwischen 20 °C und 40 °C sind Minderungsfaktoren festgelegt in EN 1555-5:2021.
EN 1555 deckt einen Bereich von maximal zulässigen Betriebsdrücken ab und enthält Anforderungen bezüglich Farben.
Drei Arten von Rohren werden behandelt:
— PE-Rohre (Außendurchmesser dn) einschließlich sämtlicher Identifizierungsstreifen;
— PE-Rohre mit koextrudierten Schichten auf der Außen- und/oder der Innenfläche des Rohres (Gesamt-Außendurchmesser dn), wie in Anhang A festgelegt, wobei alle Schichten den gleichen MRS-Wert aufweisen. Ein koextrudiertes Rohr, das aus einer Kombination von PE-100- und PE-100-RC-Schichten besteht, ist als PE-100-Rohr zu betrachten und muss entsprechend gekennzeichnet werden;
— PE-Rohre (Außendurchmesser dn) mit einer abziehbaren zusätzlichen thermoplastischen Schicht, anliegend auf der Außenfläche des Rohres („beschichtetes Rohr“), wie in Anhang B festgelegt.
ANMERKUNG 2 Es liegt in der Verantwortung des Auftraggebers oder Planers, aus diesen Kriterien die geeignete Auswahl zu treffen, unter Berücksichtigung ihrer speziellen Anforderungen und jeglicher maßgebender nationaler Festlegungen und Verfahrensweisen oder Vorschriften für die Verlegung.
Systèmes de canalisations en plastique pour la distribution de combustibles gazeux - Polyéthylène (PE) - Partie 2 : Tubes
Le présent document spécifie les caractéristiques des tubes en polyéthylène (PE) pour les systèmes de
canalisations destinés à la distribution de combustibles gazeux.
Il spécifie également les paramètres d’essai pour les méthodes d’essai référencées dans le présent
document.
Conjointement avec les Parties 1 et 3 à 5 de l’EN 1555, il s’applique aux tubes en PE et à leurs
assemblages, ainsi qu’aux assemblages avec des composants en PE et en d’autres matières, destinés à
être utilisés dans les conditions suivantes :
a) une pression maximale de service, MOP, inférieure ou égale à 10 bar11 , à une température de
référence de 20 °C pour les besoins des calculs ;
b) une température de service comprise entre –20 °C et 40 °C.
NOTE 1 Pour des températures de service comprises entre 20 °C et 40 °C, les facteurs de réduction sont définis
dans l’EN 1555-5:2021.
L’EN 1555 concerne une gamme de pressions maximales de service et donne les exigences concernant
la couleur.
Elle couvre par ailleurs trois types de tubes :
— les tubes en PE (diamètre extérieur dn) y compris les bandes d’identification éventuelles ;
— les tubes en PE comportant des couches coextrudées soit sur leur surface externe et/ou interne,
soit sur leurs deux surfaces (diamètre extérieur total dn) tel que spécifié dans l’Annexe A, où toutes
les couches ont la même classification MRS ; Un tube coextrudé constitué d’une combinaison de
couches de PE 100 et de PE 100-RC doit être considéré comme du PE 100 et marqué en
conséquence.
— les tubes en PE (diamètre extérieur dn) comportant une couche supplémentaire thermoplastique
contiguë pelable sur leur surface externe (« tube revêtu »), tel que spécifié dans l’Annexe B.
NOTE 2 Il est de la responsabilité de l’acheteur ou du prescripteur 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.

Introduction
This document specifies the requirements for a piping system and its components made from
polyethylene (PE) and which is intended to be used for the supply of gaseous fuels.
Requirements and test methods for material and components, other than pipes, are specified in
EN 1555-1, EN 1555-3 [2] and EN 1555-4 [3].
Characteristics for fitness for purpose are covered in EN 1555-5. CEN/TS 1555-7 [4] gives guidance for
assessment of conformity. Recommended practice for installation is given in EN 12007-2 [1] prepared by
CEN/TC 234.
This part of EN 1555 covers the characteristics of pipes.
