Rubber and plastic hoses and hose assemblies with internal vapour recovery for measured fuel dispensing systems - Specification
This European Standard specifies the requirements and test methods for verification for hose assemblies with vapour recovery for delivery systems on petrol filling stations. The hose assemblies with vapour recovery for delivery systems on petrol filling stations need to be capable of withstanding anticipated mechanical, thermal and chemical stressing and be resistant to the combustible liquids used in these applications as well as their vapour and vapour air mixtures. It is imperative that the assemblies be constructed in such a way that actions during normal operation cannot give rise to dangerous electrostatic charges nor that there will be any reduction in the performance of the vapour recovery. The assemblies are intended for use at ambient temperatures between -30 °C and +55 °C for normal temperature class and -40 °C and +55 °C for low temperature class at a working pressure ≤ 16 bar1). Hoses can be constructed from rubber or thermoplastic elastomer (TPE) and this document specifies the requirements for three types of hoses in two grades and two classes of hose assemblies for measured fuel dispensing systems, including oxygenated fuels (≤ 15 % oxygenated compounds) with internal vapour recovery tubing or hose.
Gummi- und Kunststoffschläuche und -schlauchleitungen mit innenliegender Gasrückführung für Zapfsäulen an Tankstellen - Anforderungen
Dieses Dokument legt Anforderungen an Schlauchleitungen mit Gasrückführung für Zapfsäulen an Tank-stellen fest. Die Schlauchleitungen mit Gasrückführung für Zapfsäulen an Tankstellen müssen den zu erwartenden mechanischen, thermischen und chemischen Beanspruchungen widerstehen können und gegen die bei diesen Anwendungen auftretenden brennbaren Flüssigkeiten sowie deren Gase und Gas-Luft-Gemische be-ständig sein. Die Schlauchleitungen müssen so ausgeführt sein, dass das Arbeiten bei Normalbetrieb keine gefährlichen elektrostatischen Aufladungen erzeugen oder die Leistung der Gasrückführung verringern kann. Die Leitungen sind für den Einsatz bei Umgebungstemperaturen vorgesehen, die für die Normaltemperatur-klasse zwischen -30 °C und +55 °C und für die Tieftemperaturklasse zwischen -40 °C und +55 °C bei einem Betriebsdruck ≤16 bar1) liegen. Die Schläuche dürfen aus Gummi oder einem thermoplastischen Elastomer (TPE) hergestellt werden, und in dem vorliegenden Dokument werden Anforderungen an drei Schlauchtypen festgelegt und zwar für zwei Kate-gorien und zwei Klassen von Schlauchleitungen für Zapfsäulen, einschließlich von Schläuchen mit innen-liegender Gasrückführung, ohne oder mit Einlage, die für mit sauerstoffhaltigen Verbindungen angereicherte Kraftstoffe vorgesehen sind (≤ 15 % sauerstoffhaltige Verbindungen). ANMERKUNG 1 Dieses Dokument gilt nicht für Mehrkammer-Zapfsäulenschläuche. ANMERKUNG 2 Als Teil der Zertifizierung einer neuen Zapfsäule sollten Kraftstoffproben nach EN 228 mindestens 8 Wochen nach der ersten Verwendung der Ausrüstung geprüft werden, um unrepräsentative Ergebnisse in Zusammen-hang mit dem Schwefelgehalt zu vermeiden.
Tuyaux et flexibles à récupération interne de vapeur pour un système de livraison mesurée carburant - Spécification
La présente Norme européenne spécifie les exigences et les méthodes d’essai pour la vérification des assemblages flexibles à récupération de vapeur des systèmes de distribution équipant les stations-service.
Il est nécessaire que les assemblages flexibles à récupération de vapeur pour les systèmes de distribution équipant les stations-service supportent les contraintes mécaniques, thermiques et chimiques prévues et soient résistant aux combustibles liquides utilisés dans ces applications ainsi qu'à leur vapeur et aux mélanges air-vapeur. Il est impératif que les assemblages soient construits de manière à ce que des actions effectuées en fonctionnement normal ne puissent pas provoquer des charges électrostatiques dangereuses, ni réduire les performances de récupération de vapeur.
Les assemblages sont destinés à être utilisés à des températures ambiantes comprises entre – 30 °C et + 55 °C pour une classe de températures normales et entre – 40 °C et + 55 °C pour une classe de basses températures à une pression de service 16 bar ).
Les tuyaux peuvent être fabriqués à partir de caoutchouc ou d'élastomères thermoplastiques (TPE) et le présent document spécifie les exigences pour trois types de tuyaux avec deux catégories et deux classes d’assemblages flexibles pour les systèmes de livraison mesurée de carburant, y compris les carburants oxygénés ( 15 % composés oxygénés) avec tube ou tuyau interne de récupération de vapeur.
NOTE La présente Norme européenne ne s’applique pas aux tuyaux multi-chambres pour distribution de carburants.
Dans le cadre de la certification d’un nouveau distributeur, il convient qu’un essai d’échantillons de carburant selon l’EN 228 soit réalisé au moins huit semaines après la première utilisation de l'équipement afin d'éviter des résultats en teneur en soufre peu représentatifs.
Gumene in polimerne cevi ter cevni priključki z notranjim sistemom za rekuperiranje hlapov za sisteme za merjeno točenje goriva na bencinskih črpalkah - Specifikacija
Ta evropski standard določa preskusne metode za preverjanje cevnih priključkov s sistemom za rekuperiranje hlapov za sisteme dovajanja na bencinskih črpalkah. Cevni priključki s sistemom za rekuperiranje hlapov za sisteme dovajanja na bencinskih črpalkah morajo vzdržati pričakovane mehanske, toplotne in kemijske obremenitve ter biti odporni na gorljive tekočine, s katerimi se uporabljajo, ter na njihove hlape in njihove mešanice z zrakom. Nujno je, da so ti priključki zasnovani tako, da njihovi vplivi med običajnim delovanjem ne povzročajo nevarnega elektrostatičnega naboja in zmanjšanega delovanja pri rekuperiranju hlapov. Priključki so namenjeni uporabi pri temperaturi okolice med -30 °C in +55 °C za običajni temperaturni razred ter -40 °C in +55 °C za nizki temperaturni razred pri delovnem tlaku ≤ 16 barov1). Cevi so lahko izdelane iz gume ali plastomernih elastomerov (TPE); ta dokument določa zahteve za tri vrste cevi v dveh tipih in dva razreda cevnih priključkov za sisteme za merjeno točenje goriva, vključno z oksigeniranimi gorivi (≤ 15 % kisikovih spojin), z notranjim priključkom ali cevjo za rekuperiranje hlapov.
