Cryogenic vessels - Static non-vacuum insulated vessels - Part 2: Design, fabrication, inspection and testing
This European Standard specifies requirements for the design, fabrication, inspection and testing of static non-vacuum insulated cryogenic vessels designed for a maximum allowable pressure of more than 0,5 bar.
This European standard applies to static non-vacuum insulated cryogenic vessels for fluids as specified in prEN 14197-1 and does not apply to vessels designed for toxic fluids.
For static non-vacuum insulated cryogenic vessels designed for a maximum allowable pressure of not more than 0,5 bar this European Standard may be used as a guide
Kryo-Behälter - Ortsfeste, nicht vakuum-isolierte Behälter - Teil 2: Bemessung, Herstellung und Prüfung
Diese Europäische Norm gilt für die Bemessung, Herstellung und Prüfung von ortsfesten, nicht vakuum-isolierten Kryo-Behältern, die für einen höchstzulässigen Betriebsdruck von über 0,5 bar bemessen sind.
Diese Norm gilt für ortsfeste, nicht vakuum-isolierte Kryo-Behälter für Fluide, die in EN 14197-1 festgelegt sind, und sie gilt nicht für giftige Fluide.
Für ortsfeste, nicht vakuum-isolierte Kryo-Behälter mit einem höchstzulässigen Betriebsdruck von weniger als 0,5 bar kann diese Norm als eine Richtlinie angewendet werden.
Récipients cryogéniques - Récipients statiques, non isolés sous vide - Partie 2: Conception, fabrication, inspection et essais
La présente Norme européenne spécifie les exigences relatives à la conception, à la fabrication, à l'inspection et aux essais de récipients cryogéniques statiques non isolés sous vide conçus pour une pression maximale admissible supérieure à 0,5 bar.
La présente Norme européenne s'applique aux récipients cryogéniques statiques non isolés sous vide destinés à contenir les fluides tels que spécifiés dans l'EN 14197-1 et ne s'applique pas aux récipients conçus pour des fluides toxiques.
La présente Norme européenne peut servir de guide pour les récipients cryogéniques statiques non isolés sous vide prévus pour une pression maximale admissible inférieure ou égale à 0,5 bar.
