DIN EN 14427:2014-09

DIN EN 14427 specifies minimum requirements for materials, design, construction, prototype testing and routine manufacturing inspections of fully wrapped composite cylinders with a water capacity from 0,5 litre up to and including 150 litres for liquefied petroleum gases (LPG) exposed to ambient temperatures, with a test pressure of at least 30 bar. The standard is only applicable to cylinders which are fitted with a pressure relief valve. The standard is applicable to cylinders with a liner of metallic material (welded or seamless) or non-metallic material (or a mixture thereof), reinforced by fibres of glass, carbon or aramid (or a mixture thereof), but also to composite cylinders without liners. Cylinders manufactured according to this European Standard are suitable for temperatures down to -40 °C. This European Standard does not address the design, fitting and performance of removable protective sleeves. Where these are fitted, the choice of material and sleeve performance should be considered separately. The previous edition DIN EN 14427:2006-03 completely revised to be in line with the improved process engineering. The committee responsible for this standard is NA 016-00-06 AA "Flüssiggas-Geräte und Ausrüstung; Spiegelausschuss zu CEN/TC 286" ("LPG equipment and accessories; National mirror committee to CEN/TC 286") at DIN.
