Thermoplastic and flexible metal pipework for underground installation at petrol filling stations

This European Standard specifies requirements for underground pipework systems used to transfer liquid fuels and their vapours at petrol filling stations. Minimum performance requirements covering fitness for purpose, safety and environmental protection are given.
This European Standard applies to pipework made from thermoplastics, which may include some degree of reinforcement, and to flexible metal pipework. It does not apply to fibre reinforced thermosets, commonly referred to as glass fibre reinforced plastic (GRP), nor to rigid metals.
This document applies to:
-   delivery pipes from tanks to dispensers, including positive pressure, vacuum suction and siphon modes;
-   fill pipes from road tankers to tanks;
-   vapour recovery and vent pipework;
-   pipework for secondary containment;
-   fittings.
It does not apply to pipework for use with liquefied petroleum gas.

Thermoplastische und flexible metallene Rohrleitungen für erdverlegte Installationen für Tankstellen

Dieses Dokument legt Anforderungen an erdverlegte Rohrleitungssysteme fest, die für die Beförderung von flüssigen Kraftstoffen und deren Dämpfen an Tankstellen eingesetzt werden. Angegeben sind Mindestleistungsanforderungen an Gebrauchstauglichkeit, Sicherheit und Umweltschutz.
Dieses Dokument gilt für Rohrleitungen aus thermoplastischen Kunststoffen, die einen bestimmten Anteil an Verstärkungswerkstoffen enthalten können, und für flexible Rohrleitungen aus Metall. Es gilt weder für faserverstärkte Duroplaste, üblicherweise als glasfaserverstärkte Kunststoffe (GFK) bezeichnet, noch für biegesteife Metalle.
Dieses Dokument gilt für:
-   Förderrohre von Tanks zu Zapfsäulen, einschließlich in Überdruck-, Vakuumsaug- und Siphon-Betriebsart;
-   Füllleitungen von Straßentankfahrzeugen zu Tanks;
-   Gasrückführ- und Entlüftungsleitungen;
-   Rohrleitungen für Schutzrohre;
-   Rohrverbindungsstücke.
Es gilt nicht für Rohrleitungen für den Transport von Flüssiggas.

Tuyauteries enterrées thermoplastiques et en métaux flexibles pour stations service

Le présent document spécifie les exigences pour les systèmes de tuyauterie enterrée utilisés pour le transport de carburants liquides et leurs vapeurs vers les stations service. Les exigences minimales de performance en matière d'aptitude à l'emploi, de sécurité et de protection de l'environnement sont indiquées.
Le pésent document s'applique à la tuyauterie enterrée thermoplastique, qui peuvent comporter un certain degré de renforcement, et aux tuyauteries métalliques flexibles. Le présent document ne s'applique pas aux thermodurcissables renforcés de fibres, communément appelés plastiques renforcés de fibres de verre (PRV), ni aux métaux rigides.
Le présent document s'applique aux domaines suivants :
-   les tuyaux de distribution des réservoirs aux distributeurs, y compris les modes de pression positive, d'aspiration par le vide et de siphon ;
-   les tuyaux de remplissage des camions-citernes vers les réservoirs ;
-   la récupération des vapeurs et la tuyauterie d'aération ;
-   la tuyauterie de confinement secondaire ;
-   les raccords
Le présent document ne s'applique pas aux tuyauteries destinées à être utilisées avec des gaz de pétrole liquéfiés.
