Gas Infrastructure - Gas installation pipework with an operating pressure greater than 0,5 bar for industrial installations and greater than 5 bar for industrial and non-industrial installations - Part 1: Detailed functional requirements for design, materials, construction, inspection and testing

This standard specifies detailed functional requirements for the design, selection of materials, construction, inspection and testing of industrial gas installation pipework and assemblies with an operating pressure greater than 0,5 bar, and non industrial gas installation pipework (residential and commercial) with an operating pressure greater than 5 bar in buildings, starting from the outlet of the network operator’s point of delivery up to the inlet connection to the gas appliance; normally the inlet isolation valve. This standard also covers the inlet connection to the gas appliance comprising of the pipework that does not fall within the scope of the appliance standard.
NOTE   The use of the term installation and pipework is interchangeable.
This standard applies to gas installations operating at ambient temperatures between - 20 °C and 40 °C and operating pressures up to and including 60 bar. For operating conditions outside these limitations, reference should additionally be made to EN 13480 for metallic pipework.
For industrial gas installations up to and including 0,5 bar and for non industrial (residential and commercial) gas installations up to and including 5 bar in buildings, EN 1775 applies.
For gas installations that do not fall within the scope of EN 1775 or other European Standards, this standard applies.
In this standard, the term “gas“ refers to combustible gases, which are gaseous at 15 °C and 1 013 mbar absolute atmospheric pressure (normal conditions). These gases are commonly referred to as manufactured gas, natural gas or Liquefied Petroleum Gas (LPG). They are also referred to as first, second or third family gases (see Table 1 of EN 437:2003). The given values are considered as normal conditions for all volumes given in this standard.

Gasinfrastruktur - Gasleitungsanlagen mit einem Betriebsdruck größer 0,5 bar für industrielle Installationen und größer 5 bar für industrielle und nicht-industrielle Installationen - Teil 1: Detaillierte funktionale Anforderungen an Planung, Material, Bau, Inspektion und Prüfung

Diese Europäische Norm legt detailliert die funktionalen Anforderungen hinsichtlich der Planung und Werkstoffauswahl sowie des Baus, der Inspektion und der Prüfung von:
-   industriellen Gasleitungsanlagen und Baugruppen mit einem Betriebsdruck größer 0,5 bar; und
-   nicht-industriellen Gasleitungsanlagen in Gebäuden (Haushalte und Gewerbebetriebe) mit einem Betriebsdruck größer 5 bar,
beginnend am Ausgangsanschluss der Übergabestelle des Netzbetreibers bis zum Eingangsanschluss der Gasgeräte, d. h. in der Regel der Absperrarmatur vor dem Gerät, fest. Diese Norm gilt auch für die Rohrleitungen zum Eingangsanschluss der Gasgeräte, die nicht in den Anwendungsbereich der Gasgerätenorm fallen.
ANMERKUNG 1   Der Gebrauch der Begriffe "Anlage" (en: installation) und "Rohrleitungen" (en: pipework) ist austauschbar.
Abgesehen von den nachstehend angegebenen Ausnahmen gilt diese Norm für den Betrieb von Gasleitungsanlagen bei Umgebungstemperaturen zwischen −20 °C und 40 °C mit Betriebsdrücken bis einschließlich 60 bar. Bei Betriebszuständen außerhalb dieser Grenzen sollte zusätzlich auf EN 13480 (alle Teile) für metallische Rohrleitungen Bezug genommen werden.
Für industrielle Gasleitungsanlagen mit Betriebsdrücken bis einschließlich 0,5 bar und für nicht-industrielle Gasleitungsanlagen in Gebäuden (Haushalten und Gewerbebetrieben) mit Betriebsdrücken bis einschließlich 5 bar gilt EN 1775.
Diese Norm gilt für Gasleitungsanlagen, die nicht in den Anwendungsbereich der EN 1775 oder anderer Europäischer Normen fallen.
In dieser Europäischen Norm bezeichnet der Begriff „Gas“ brennbare Gase, die bei einer Temperatur von 15 °C und einem absoluten atmosphärischen Druck von 1 013 mbar (Normalzustand) in gasförmigem Zustand vorliegen. Diese Gase werden im Allgemeinen als erzeugtes Gas, Erdgas oder Flüssiggas (LPG) bezeichnet. Sie werden auch als Gase der ersten, zweiten oder dritten Gasfamilie entsprechend der Klassifizierung nach EN 437:2003+A1:2009, Tabelle 1, bezeichnet. Die angegebenen Werte beziehen sich auf den "Normalzustand" für alle in dieser Norm angegebenen Volumina.
Diese Europäische Norm gilt für Rohrleitungsanlagen für den Transport von:
-   aufbereitetem, ungiftigem und nicht korrosivem Erdgas nach EN 437:2003+A1:2009 und EN 16726 "Gasinfrastruktur - Beschaffenheit von Gas - Gruppe H";
-   verdampftem LPG;
-   Biomethan nach EN 16723 1;
-   verdampftem LNG.
ANMERKUNG 2   Die Spezifikation von verdampftem LNG gleicht der von Erdgas entsprechend der Klassifizierung nach EN 437:2003+A1:2009.
Diese Europäische Norm gilt nicht für Rohrleitungen für Gase mit hohem Wasserstoffanteil, die nicht den Definitionen nach EN 437:2003+A1:2009 entsprechen.
Hiervon ausgenommen sind Flüssiggasbehälter (einschließlich aller unmittelbar an den Behältern angebrachten Geräte). Ebenfalls ausgenommen sind Flüssiggasanlagen und Abschnitte von Flüssig-gasanlagen, die in flüssigem Zustand unter Dampfdruck betrieben werden (z. B. zwischen dem Behälter und einem Druckregelgerät).
Sofern nicht anders angegeben, handelt es sich bei allen in diesem Dokument verwendeten Drücken um Überdrücke.
Diese Norm wurde im Hinblick auf die grundlegenden Sicherheitsanforderungen an das Verbinden von Gasleitungsanlagen (Baugruppen), die in den Anwendungsbereich der PED fallen, an die Druckgeräte-richtlinie (PED, 2014/68/EU [zuvor PED, 97/23/EG]) angepasst. Diese Anforderungen sind in Anhang ZA aufgeführt. Allerdings gilt diese Richtlinie "nicht für den Zusammenbau von Druckgeräten..., der " beispielsweise in Industrieanlagen " auf dem Gelände und unter der Verantwortung eines Anwenders erfolgt." (PED, Präambel, 7. Aufzählung, letzter Absatz).
Diese Norm berücksichtigt in diesem Zusammenhang zwar die grundlegenden Sicherheitsanforderungen der PED, allerdings kann sich daraus nicht ableiten lassen, ob eine Anlage ganz oder teilweise in den Anwendungsbereich der PED fällt. (...)

Infrastructures gazières - Canalisations d’installations de gaz avec une pression de service supérieure à 0,5 bar pour les installations industrielles et supérieure à 5 bar pour les installations industrielles et non industrielles (domestiques et commerciales) - Partie 1 : Exigences fonctionnelles détaillées relatives à la conception, aux matériaux, à la construction, à l'inspection et aux essais

Cette Norme européenne spécifie les exigences fonctionnelles détaillées relatives à la conception, au choix des matériaux, à la construction, à l’inspection et aux essais :
-   d’installations et d'ensembles industriels de gaz avec une pression de service supérieure à 0,5 bar ; et
-   d’installations de gaz non industrielles (résidentielles et commerciales) avec une pression de service supérieure à 5 bar dans les bâtiments ;
allant du point de livraison de l'exploitant du réseau de distribution de gaz jusqu'au raccordement d'entrée de l'appareil à gaz, ce dernier étant habituellement le robinet d'isolement d'entrée. La présente norme est aussi applicable à la tuyauterie du raccordement d’un appareil à gaz qui ne fait pas partie du domaine d'application de la norme de l'appareil.
NOTE 1   Les termes installation et tuyauterie sont interchangeables.
Outre les exceptions énoncées ci-après, la présente norme est applicable aux installations de gaz exploitées à des températures ambiantes comprises entre −20 °C et 40 °C et des pressions de service inférieures ou égales à 60 bar. Pour des conditions de service en dehors de ces limites, il convient de se référer à l’EN 13480 (toutes les parties) dans le cas d’une canalisation métallique.
Pour les installations de gaz industrielles dont la pression de service est inférieure ou égale à 0,5 bar et pour les installations de gaz non industrielles (domestiques et commerciales) dont la pression de service est inférieure ou égale à 5 bar dans des bâtiments, c'est l’EN 1775 qui s’applique.
Pour les installations industrielles de gaz non visées par l’EN 1775 ni par d'autres Normes européennes, cette norme s’applique.
Dans la présente Norme européenne, le terme « gaz » est applicable à des gaz combustibles, qui sont gazeux à 15 °C et à 1 013 mbar de pression atmosphérique absolue (conditions normales). Ces gaz sont couramment appelés gaz manufacturé, gaz naturel ou gaz de pétrole liquéfiés (GPL). Ils sont aussi dénommés respectivement gaz de la 1ère, 2e et 3e famille selon le classement de l’EN 437:2003+A1:2009, Tableau 1. Les valeurs données sont considérées aux conditions normales pour tous les volumes donnés dans cette norme.
La présente Norme européenne s’applique aux canalisations d'installations pour le transport du :
-   gaz traité, non toxique et non corrosif, naturel, conformément à l’EN 437:2003+A1:2009 et à l’EN 16726, « Infrastructures gazières - Qualité du gaz - Groupe H » ;
-   GPL vaporisé ;
-   biométhane, conforme à l’EN 16723-1 ;
-   GNL vaporisé.
NOTE 2   La spécification du GNL vaporisé équivaut à celle du gaz naturel classé dans l’EN 437:2003+A1:2009.
La présente Norme européenne ne couvre pas la tuyauterie pour les gaz riches en hydrogène ne relevant pas de la définition figurant dans l’EN 437:2003+A1:2009.
Les réservoirs de stockage de GPL (y compris tous les accessoires fixés directement sur les réservoirs de stockage) sont exclus. Il en est de même pour les installations de GPL et les parties d'installations de GPL exploitées à la pression de vapeur à l’état liquide (par exemple entre le réservoir de stockage et chaque régulateur de pression).
Dans cette norme, toutes les pressions sont, sauf indication contraire, des pressions relatives.
Cette norme a été harmonisée pour satisfaire aux exigences essentielles de la Directive relative aux équipements sous pression (DESP, 2014/68/UE [anciennement 97/23/CE]) en matière de raccordement de canalisations d'installations de gaz (ensembles) qui entrent dans le domaine d'application de la DESP. Ces exigences sont listées en Annexe ZA. Cependant, « cette Directive ne couvre pas l’assemblage d’équipements sous pression effectué sur le site de l’usager, sous la responsabilité de celui-ci, telles que des installations industrielles » (...)
