Cryogenic vessels - Large transportable non-vacuum insulated vessels - Part 2: Design, fabrication, inspection and testing
This European Standard specifies requirements for the design, fabrication, inspection and testing of large transportable non vacuum insulated cryogenic vessels of more than 1000 l volume, which are permanently (fixed tanks) or not permanently (demountable tanks) attached to a vehicle, for carriage by road. However, it can be used for other mode of transport providing the specific regulations/requirements are complied with.
This European Standard applies to large transportable non vacuum insulated cryogenic vessels for fluids specified in prEN 14398-1 and does not apply to vessels designed for toxic fluids.
This European Standard does not include the general vehicle requirements e.g. running gear, brakes, lighting etc. that shall be in accordance with the relevant standards/regulations.
Kryo-Behälter - Große ortsbewegliche, nicht vakuum-isolierte Behälter - Teil 2: Bemessung, Herstellung, Überwachung und Prüfung
Diese Europäische Norm gilt für die Bemessung, Herstellung und Prüfung von großen ortsbeweglichen, nicht vakuum-isolierten Kryo-Behältern mit einem Fassungsraum von mehr als 1 000 Litern für festverbundene Tanks (von Tank- oder Schienenfahrzeugen), Aufsetztanks, Tanks von Batterie-Fahrzeugen und Tankcontainern (TC) für tiefgekühlte verflüssigte Gase im Sinne der Regelungen für die Beförderung gefährlicher Güter.
Diese Norm gilt für große ortsbewegliche, nicht vakuum-isolierte Kryo-Behälter für Fluide, die in EN 14398-1 festgelegt sind, und sie gilt nicht für giftige Fluide.
Diese Europäische Norm enthält keine allgemeinen Anforderungen an Fahrzeuge wie z. B. an Fahrgestell, Bremsen, Beleuchtung usw., diese müssen mit den relevanten Normen/Gesetzen übereinstimmen.
Récipients cryogéniques - Grands récipients transportables non isolés sous vide - Partie 2: Conception, fabrication, inspection et essais
La présente Norme européenne spécifie des exigences en matière de conception, fabrication, contrôle et essais de grands récipients cryogéniques transportables non isolés sous vide d'un volume supérieur à 1 000 l, fixés sur un véhicule de manière permanente (réservoirs fixes) ou non (réservoirs démontables) pour le transport routier. Elle peut cependant être utilisée pour d'autres modes de transport à condition que soient respectées les lois et exigences correspondantes.
La présente Norme européenne s'applique aux grands récipients cryogéniques transportables non isolés sous vide pour les fluides spécifiés dans l'EN 14398-1 et ne s'applique pas à des récipients prévus pour contenir des fluides toxiques.
La présente Norme européenne ne couvre pas les exigences générales relatives aux véhicules, par exemple, les organes de roulement, les freins, les feux, etc., qui doivent être conformes aux normes/règlements correspondants.
