Overfill prevention devices for static tanks for liquid petroleum fuels
This standard specifies the minimum performance and construction requirements for various types of overfill prevention devices which are limited to static tanks of shop fabricated manufacture both metallic and non metallic. It covers devices for underground tanks and also above ground tanks with a maximum height of 5 m.
To cover the different types of overfill prevention devices, two types have been developed:
3 Type A: An overfill prevention device where the operation does not depend on the road tank vehicle or supply system;
3 Type B: An overfill prevention device where the operation depends on the road tank vehicle or the supply system.
This standard applies to overfill prevention devices for liquid petroleum fuels, having a flash point up to but not exceeding 100 °C. The requirements apply to overfill prevention devices suitable for use at ambient temperatures in the range from -25°C to +60°C, and subject to normal operational pressure variations.
Überfüllsicherungen für ortsfeste Tanks für flüssige Brenn- und Kraftstoffe
Diese Norm legt die Mindestleistungsanforderungen an unterschiedliche Bauarten von Überfüllsicherungen fest, deren Einsatz auf metallische oder nichtmetallische ortsfeste werksgefertigte Tanks begrenzt ist. Es werden Einrichtungen für unterirdische Tanks und auch für oberirdische Tanks mit einer Maximalhöhe von 5 m behandelt.
Für die Beschreibung der unterschiedlichen Bauarten von Überfüllsicherungen wurden zwei Typen gebildet:
- Typ A: Überfüllsicherung, deren Funktion nicht von einem Versorgungsfahrzeug oder Versorgungssystem abhängig ist;
- Typ B: Überfüllsicherung, deren Funktion von einem Versorgungsfahrzeug oder Versorgungssystem abhängig ist.
Diese Norm gilt für Überfüllsicherungen in Tanks für Brenn- und Kraftstoffe, die einen Flammpunkt L 100 °C haben. Die Anforderungen gelten für Überfüllsicherungen, die bei Umgebungstemperaturen im Bereich von -25 °C bis +60 °C eingesetzt werden können und nur betriebsbedingten Druckschwankungen ausgesetzt sind.
Zusätzliche Maßnahmen können für den Gebrauch und die Lagerung bei Umgebungstemperaturen außerhalb dieses Bereichs verlangt werden und sind zwischen dem Hersteller und seinem Kunden auszuhandeln.
Dispositifs limiteurs de remplissage pour réservoirs statiques pour carburants pétroliers liquides
La présente norme spécifie les prescriptions minimales de performance et de construction applicables a différents types de dispositifs limiteurs de remplissage utilisés uniquement sur des réservoirs statiques métalliques ou non métalliques fabriqués en usine. Elle concerne également les dispositifs pour réservoirs enterrés et aériens d'une hauteur maximale de 5 m.
Afin de couvrir les différents types de dispositifs limiteurs de remplissage, deux catégories sont définies :
3 catégorie A : dispositif limiteur de remplissage dont le fonctionnement ne dépend pas du véhicule de ravitaillement ou du systeme d'alimentation ;
3 catégorie B : dispositif limiteur de remplissage dont le fonctionnement dépend du véhicule de ravitaillement ou du systeme d'alimentation.
La présente norme s'applique aux dispositifs limiteurs de remplissage pour carburants pétroliers ayant un point d'éclair inférieur ou égal a 100 °C. Les prescriptions s'appliquent aux dispositifs limiteurs de remplissage fonctionnant a des températures ambiantes comprises entre - 25 °C et + 60 °C et soumis a des variations de pression normales de fonctionnement.
Des mesures supplémentaires peuvent etre requises pour un usage a des températures extérieures a cette plage et doivent etre soumis a des négociations entre le fabricant et son client.
