Transportable gas cylinders - Refillable welded receptacles of a capacity not exceeding 150 litres - Part 1: Welded austenitic stainless steel cylinders made to a design justified by experimental methods
This European Standard gives minimum requirements concerning material, design, construction and workmanship, procedures and tests at manufacture of refillable transportable welded cylinders made of austenitic stainless steel, justified by experimental methods, of water capacities from 0,5 l up to and including 150 l for compressed or liquefied gases and of a test pressure up to 90 bar.
NOTE This European Standard may also be used as a guideline for cylinders less than 0,5 litres water capacity.
This European Standard is primarily for industrial gases other than LPG but may also be applied for LPG. However for dedicated LPG cylinders, see EN 14140, Transportable refillable welded steel cylinders for liquefied petroleum gas (LPG) Alternative design and construction prepared by CEN/TC 286 Liquefied petroleum gas equipment and accessories.
Ortsbewegliche Gasflaschen - Wiederbefüllbare geschweißte Gefäße mit einem Fassungsraum von nicht mehr als 150 Liter - Teil 1: Flaschen aus geschweißtem, austenitischen, nichtrostendem Stahl, ausgelegt nach experimentellen Verfahren
Diese Europäische Norm legt Mindestanforderungen an Werkstoff, Gestaltung, Konstruktion und Ausführung,
Verfahren und Prüfung bei der Herstellung wiederbefüllbarer, ortsbeweglicher, geschweißter Flaschen aus
austenitischem, nichtrostendem Stahl fest, ausgelegt nach dem experimentellen Verfahren, mit Fassungs-räumen
von 0,5 l bis einschließlich 150 l für unter Druck gesetzte Gase oder Flüssiggase (LPG, en.: liquefied
petroleum gas) und für einen Prüfdruck von bis zu 90 bar.
ANMERKUNG Diese Europäische Norm darf auch als Leitlinie für Flaschen mit einem Fassungsraum von weniger als
0,5 l angewendet werden.
Diese Europäische Norm gilt hauptsächlich für andere Gase für den industriellen Einsatz als LPG, darf jedoch
ebenfalls auf LPG angewendet werden. Für Flaschen, die für LPG vorgesehen sind, siehe EN 14140,

Bouteilles à gaz transportables - Récipients soudés rechargeables d'une capacité inférieure ou égale à 150 litres - Partie 1: Bouteilles en acier inoxydable austénitique soudées conçues par des méthodes expérimentales
La présente Norme européenne indique les exigences minimales concernant les matériaux, la conception, la fabrication et la mise en oeuvre, les modes opératoires et les essais lors de la fabrication des bouteilles soudées transportables et rechargeables, fabriquées en acier inoxydable austénitique et conçues par des méthodes expérimentales. Ces bouteilles ont une capacité en eau comprise entre 0,5 l et 150 l inclus, une pression d’épreuve jusqu'à 90 bar et sont destinées à contenir des gaz comprimés ou liquéfiés.
NOTE La présente Norme européenne peut également être utilisée comme lignes directrices pour les bouteilles d’une capacité en eau inférieure à 0,5 l.
Bien que la présente Norme européenne porte principalement sur les gaz industriels autres que le GPL, elle peut également s’y appliquer. Toutefois, pour les bouteilles destinées à contenir du GPL, se reporter à l’EN 14140, Bouteilles en acier soudé transportables et rechargeables pour gaz de pétrole liquéfié (GPL) Autres solutions en matière de conception et de construction élaborée par le CEN/TC 286 Équipements et accessoires pour gaz de pétrole liquéfié.
