(Main)LPG equipment and accessories - Equipping of LPG road tankers
LPG equipment and accessories - Equipping of LPG road tankers
This European Standard specifies equipment and accessories for road tankers used for the transport of Liquefied Petroleum Gas (LPG) and identifies the equipment that is considered necessary to ensure that filling, transportation and discharge operations can be carried out safely. It also specifies the requirements for the assembly of the accessories and the vehicle LPG equipment to the road tanker.
This European Standard also identifies additional equipment and accessories that may be used on road tankers carrying LPG.
NOTE This European Standard does not preclude the use of alternative designs, materials and equipment testing which provide a similar level of safety.
This European Standard does not apply to "tank-containers" and "battery-vehicles" used for the transportation of LPG.
Flüssiggas-Geräte und Ausrüstungsteile - Ausrüstung von Straßentankwagen für Flüssiggas (LPG)
Diese Europäische Norm legt die Ausstattung und das Zubehör von Straßentankwagen fest, die zum Transport von Flüssiggas (LPG) eingesetzt werden, und beschreibt die als notwendig betrachtete Ausrüstung zur sicheren Durchführung von Füll-, Transport- und Entleerungsvorgängen. Sie legt auch die Anforderungen an den Zusammenbau des Zubehörs und die Fahrzeugausrüstung für Flüssiggas (LPG) von Straßentankwagen fest.
Die Europäische Norm beschreibt auch zusätzliche Ausrüstung und Zubehör, die auf mit Flüssiggas beladenen Straßentankwagen verwendet werden können.
ANMERKUNG Diese Europäische Norm sollte nicht die Anwendung alternativer Auslegungen, Werkstoffe und Ausrüstungen ausschließen, um zu überprüfen, welche ein gleichwertiges Sicherheitsniveau haben.
Diese Norm gilt nicht für "Tankcontainer" bzw. "Batterie-Fahrzeuge", die beim Transport von Flüssiggas Verwendung finden.
Equipements pour GPL et leurs accessoires - Equipements des camions citernes pour GPL
La présente Norme européenne spécifie les équipements et accessoires pour camions-citernes destinés au transport de gaz de pétrole liquéfié (GPL) et identifie les équipements considérés comme nécessaires pour que les opérations de remplissage, de transport et de déchargement puissent être effectuées en toute sécurité. Elle spécifie également les exigences relatives à l’assemblage des accessoires et des équipements GPL du véhicule sur le camion-citerne.
La présente Norme européenne identifie également les équipements et accessoires supplémentaires qui peuvent être utilisés sur des camions-citernes destinés au transport de GPL.
NOTE La présente Norme européenne n’exclut pas l’utilisation de conceptions, de matériaux et de méthodes d’essais des équipements qui diffèrent, à condition qu’ils présentent un niveau de sécurité équivalent.
La présente Norme européenne ne s’applique pas aux "conteneurs-citernes", ni aux "véhicules batteries" utilisés pour le transport du GPL.
