EN 12257:2002
(Main)Transportable gas cylinders - Seamless, hoop-wrapped composite cylinders
Transportable gas cylinders - Seamless, hoop-wrapped composite cylinders
This European Standard specifies minimum requirements for the materials, design, construction, prototype testing and routine manufacturing inspections of composite gas cylinders with a water capacity up to and including 450 litres for compressed, liquefied and dissolved gases.
NOTE For the purposes of this standard, the word "cylinder" includes tubes up to 450 litres water capacity.
This standard is applicable to cylinders that comprise a seamless metal liner reinforced over a substantial part of the parallel length by wound composite fibres of glass, carbon, aramid, or wire.
This standard is not applicable to gas cylinders which are almost totally covered with fibres and commonly called "fully-wrapped" cylinders. For fully-wrapped composite cylinders see prEN 12245.
NOTE The specification does not address the design, fitting and performance of removable protective sleeves. Where these are fitted they should be considered separately.
Ortsbewegliche Gasflaschen - Nahtlose umfangsgewickelte Flaschen aus Verbundwerkstoffen
Diese Norm enthält Mindestanforderungen an die Werkstoffe, die Gestaltung, Konstruktion, die Bauartzulassungen, Baureihen- und Abnahmeprüfungen von Flaschen aus Verbundwerkstoffen mit einem Fassungsraum bis zu 450 Litern für verdichtete, verflüssigte und unter Druck gelöste Gase.
ANMERKUNG Für die Anwendung dieser Norm umfasst das Wort "Flasche" auch Großflaschen mit einem Fassungsraum bis zu 450 Litern.
Diese Norm ist auf Flaschen anwendbar, die aus einem nahtlosen Liner aus Metall bestehen, und die über den größten Teil der parallelen Länge mit einem Wickelverbund aus Glas-, Kohlenstoff-, Aramid- oder Stahl (Draht) verstärkt sind.
Die vorliegende Norm gilt nicht für Gasflaschen, die mit Faserwerkstoffen vollumwickelt sind und allgemein als "vollumwickelte" Flaschen bezeichnet werden. Für diese gilt EN 12245.
ANMERKUNG Diese Festlegungen beinhalten nicht die Gestaltung, Montage und das Verhalten von abnehmbaren Schutzhüllen. Dies sollte separat betrachtet werden.
Bouteilles à gaz transportables - Bouteilles sans soudure, frettées composites
La présente Norme européenne spécifie les exigences minimales relatives aux matériaux, à la conception, à la construction, aux essais de prototype et aux contrôles courants en fabrication, des bouteilles à gaz composites, d'une contenance en eau inférieure ou égale à 450 litres, pour gaz comprimés, liquéfiés et dissous.
NOTE 1 Pour les besoins de la présente norme, le mot « bouteille » englobe les tubes d'une contenance en eau inférieure ou égale à 450 l.
La présente norme s'applique aux bouteilles constituées d'un liner métallique sans soudure renforcé sur une portion substantielle de sa partie cylindrique par un enroulement composite en fibres de verre, de carbone, d'aramide ou par un fil métallique.
La présente norme ne s'applique pas aux bouteilles à gaz presque totalement recouvertes de fibres, couramment appelées "bouteilles entièrement bobinées". Pour les bouteilles composites entièrement bobinées, voir l'EN 12245.
NOTE 2 Cette spécification ne traite pas de la conception, du montage et des performances des gaines de protection amovibles. Lorsque celles-ci sont montées, il convient de les considérer séparément.
