Transportable gas cylinders - Fully wrapped composite cylinders
This document specifies minimum requirements for the materials, design, construction, prototype testing and routine manufacturing inspections of fully wrapped composite gas cylinders for compressed, liquefied and dissolved gases.
NOTE 1 For the purposes of this document, the word “cylinder” includes tubes (seamless transportable pressure receptacles of a water capacity exceeding 150 l and of not more than 3 000 l).
This document is applicable to cylinders that comprise a liner of metallic material (welded or seamless) or non-metallic material (or a mixture thereof), reinforced by a wound composite consisting of fibres of glass, carbon or aramid (or a mixture thereof) embedded in a matrix.
This document is also applicable to composite cylinders without liners.
This document is not applicable to gas cylinders which are partially covered with fibres and commonly called “hoop wrapped” cylinders. For hoop wrapped composite cylinders, see EN 12257.
NOTE 2 This document does not address the design, fitting and performance of removable protective sleeves. Where these are fitted, they are considered separately.
This document is primarily for compressed, liquefied and dissolved gases other than LPG.
NOTE 3 For dedicated LPG cylinders, see EN 14427.
Ortsbewegliche Gasflaschen - Vollumwickelte Flaschen aus Verbundwerkstoffen
Dieses Dokument legt Mindestanforderungen an die Werkstoffe, Gestaltung, Konstruktion, Prototyp-prüfungen und routinemäßigen Inspektionen während der Herstellung von vollumwickelten Gasflaschen aus Verbundwerkstoffen für verdichtete, verflüssigte und gelöste Gase fest.
ANMERKUNG 1 Für die Anwendung dieses Dokuments umfasst das Wort „Flasche“ Großflaschen (nahtlose, ortsbewegliche Druckbehälter mit einem Fassungsraum von mehr als 150 l und nicht mehr als 3 000 l).
Dieses Dokument gilt für Flaschen, die einen Liner aus metallischem Werkstoff (geschweißt oder nahtlos) oder nichtmetallischem Werkstoff (oder einer Kombination daraus) umfassen, der mit einem in einer Matrix eingebetteten Wickelverbund aus Glas-, Kohlenstoff- oder Aramidfasern (oder einer Kombination daraus) verstärkt ist.
Dieses Dokument gilt auch für Flaschen aus Verbundwerkstoffen ohne Liner.
Dieses Dokument gilt nicht für Gasflaschen, die teilweise mit Fasern eingehüllt sind und allgemein als „umfangsgewickelte“ Flaschen bezeichnet werden. Zu umfangsgewickelten Flaschen aus Verbundwerkstoffen siehe EN 12257.
ANMERKUNG 2 Dieses Dokument behandelt nicht die Konstruktion, Anbringung und Leistung von abnehmbaren Schutzhülsen. Sind derartige Schutzhüllen angebracht, werden sie separat betrachtet.
Dieses Dokument gilt hauptsächlich für verdichtete, verflüssigte und gelöste Gase, die kein Flüssiggas sind.
ANMERKUNG 3 Zu Flaschen speziell für Flüssiggas siehe EN 14427.
Bouteilles à gaz transportables - Bouteilles entièrement bobinées en matériaux composites
Le présent document spécifie les exigences minimales relatives aux matériaux, à la conception, à la construction, aux essais de prototype et aux contrôles courants de production, des bouteilles à gaz entièrement bobinées en matériaux composites pour gaz comprimés, liquéfiés et dissous.
NOTE 1 Pour les besoins du présent document, le mot « bouteille » englobe les tubes (conteneurs sous pression transportables d’une capacité en eau supérieure à 150 l, mais non supérieure à 3 000 l).
Le présent document s’applique aux bouteilles constituées d’un liner métallique (avec ou sans soudure), ou non métallique (ou constitué d’un mélange de ces matériaux), renforcé par un enroulement composite en fibres de verre, de carbone ou d’aramide (ou un mélange de ces matériaux) noyées dans une matrice.
Le présent document s’applique également aux bouteilles à gaz en composite sans liner.
Le présent document ne s’applique pas aux bouteilles à gaz partiellement recouvertes de fibres et couramment appelées « bouteilles frettées ». Pour les bouteilles frettées en matériaux composites, voir l’EN 12257.
NOTE 2 Le présent document ne traite pas de la conception, du montage et des performances des gaines de protection amovibles. Lorsque celles ci sont montées, elles sont considérées séparément.
Le présent document concerne principalement les gaz comprimés, liquéfiés et dissous autres que le GPL.
NOTE 3 Pour les bouteilles à GPL, voir l’EN 14427.
Premične plinske jeklenke - Popolnoma obvite jeklenke iz kompozitnih materialov
Ta dokument določa minimalne zahteve za materiale, projektiranje, konstrukcijo, preskušanje prototipov in redne proizvodne preglede popolnoma obvitih plinskih jeklenk iz kompozitnih materialov za stisnjene, utekočinjene in raztopljene pline.
OPOMBA 1: Za namene tega dokumenta izraz »jeklenka« vključuje cevi (nevarjene premične tlačne posode s prostornino vode več kot 150 litrov in največ 3000 litrov).
Ta dokument se uporablja za jeklenke, ki imajo oblogo iz kovinskega materiala (varjenega ali nevarjenega) ali nekovinskega materiala (ali njegove mešanice) in so ojačane s kompoziti, ki vsebujejo steklena, ogljikova ali aramidna vlakna (ali njihovo mešanico), vdelanimi v matrico.
Dokument se uporablja tudi za jeklenke iz kompozitnih materialov brez oblog.
Ta dokument se ne uporablja za plinske jeklenke, ki so delno prekrite z vlakni in običajno imenovane »obročasto obvite« jeklenke. Za jeklenke, obročasto obvite s kompozitno maso, glej standard EN 12257.
OPOMBA 2: Ta dokument ne obravnava zasnove, nameščanja in lastnosti odstranljivih zaščitnih ovitkov. Če so ti nameščeni, se obravnavajo ločeno.
Ta dokument obravnava predvsem stisnjene, utekočinjene in raztopljene pline, razen utekočinjenega naftnega plina (UNP).
OPOMBA 3: Za jeklenke, namenjene za utekočinjeni naftni plin, glej standard EN 14427.
