ANMERKUNG Diese Norm kann auch als Leitfaden für Flaschen mit einem Fassungsraum von weniger als 0,5 l angewendet werden.
Diese Europäische Norm gilt hauptsächlich für andere Industriegase als Flüssiggas (en: Liquified Petroleum Gas - LPG), kann jedoch ebenfalls für LPG angewendet werden. Für zugehörige LPG-Flaschen siehe hin-gegen EN 14140 [5], die vom CEN/TC 286 erarbeitet wurde.

capacités équivalentes en eau comprises entre 0,5 l et 150 l inclus, destinées aux gaz comprimés ou liquéfiés
et soumises à une pression d’épreuve maximale de 90 bar.
NOTE La présente Norme européenne peut également servir de guide en matière de bouteilles de capacité
équivalente en eau inférieure à 0,5 l.
La présente Norme européenne s’applique principalement aux gaz industriels autres que le gaz de pétrole
liquéfié (GPL) mais peut également concerner le GPL. Toutefois, pour les bouteilles à gaz dédiées au GPL,
se reporter à l’EN 14140 [5], élaborée par le comité technique CEN/TC 286.

Introduction The purpose of this European Standard is to provide a specification for the design, manufacture, inspection and approval of welded carbon steel gas cylinders for use in the countries of the CEN members. The specifications given in the present standard establish the methodology to be adopted to demonstrate that a cylinder conforms to the functional requirements demanded, based on experience of materials, design prescriptions, manufacturing processes and controls manufacturing. This European Standard specifies experimental methods and appropriate stress analysis calculations. It does not cover methods exclusively by means of traditional calculation. SIST EN 14638-3:2010
