Transportable gas cylinders - Fully wrapped composite cylinders
This European Standard specifies minimum requirements for the materials, design, construction, prototype testing and routine manufacturing inspections of composite gas cylinders for compressed, liquefied and dissolved gases.
NOTE 1 For the purposes of this European Standard, the word "cylinder" includes tubes (seamless transportable pressure receptacles of a water capacity exceeding 150 litres and of not more than 3 000 litres).
This European Standard 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 European Standard is also applicable to composite cylinders without liners.
This European Standard 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 European Standard does not address the design, fitting and performance of removable protective sleeves. Where these are fitted, they should be considered separately.
This European Standard is primarily for industrial gases other than LPG but may also be applied to LPG.
NOTE 3 For dedicated LPG cylinders, see EN 14427.

Umgebungstemperatur 5.2.6.1 Für unbegrenzte Lebensdauer 5.2.6.1.1 Durchführung Der Lastwechselversuch ist auf einem Prüfstand durchzuführen, der einen kontrollierten Druckanstieg und -abfall ermöglicht und die Prüfung automatisch abbricht, wenn die Flasche infolge Undichtigkeit oder Bruch versagt. Ist eine Flasche nur für den Einsatz mit einem oder mehreren spezifischen Gas(en) vorgesehen, darf die Konstruktion als Spezialanfertigung für dieses Gas bezeichnet werden. Die für die Flasche zulässigen Gase sind eindeutig auf dem Flaschenetikett anzugeben (siehe Abschnitt 7). Die Prüfung ist mit einer nicht korrodierend wirkenden Flüssigkeit durchzuführen, wobei die Flasche nacheinander Lastwechseln auszusetzen ist, bei denen der obere zyklische Druck für nicht festgelegte Gase gleich dem hydraulischen Prüfdruck (ph) bzw. für das spezielle Gas, das den höchsten Druck entwickelt, gleich dem bei 65 °C entwickelten Höchstdruck, pmax, sein muss. Der Wert des unteren zyklischen Drucks darf 10 % des oberen zyklischen Drucks nicht überschreiten, wobei der absolute Höchstwert bei 30 bar liegt. Die Flasche muss bei dieser Prüfung dem tatsächlichen höchsten und dem tatsächlichen geringsten zykli-schen Druck ausgesetzt werden. Die Lastwechselversuche sind unter Umgebungsbedingungen durchzuführen, und die Temperatur der Außen-fläche der Flasche darf während der Prüfung 50 °C nicht überschreiten. Die Frequenz der Druckwechsel darf 0,25 Hz (15 Lastwechsel je Minute) nicht überschreiten. Die Temperatur der Außenfläche der Flasche ist mindestens zweimal täglich zu überwachen. Die während der Prüfung erreichte Anzahl der Lastwechsel ist aufzuzeichnen. Nach Abschluss dieser Prüfung sind die Flaschen zu zerstören (z. B. durch Bersten) oder für das Druckhalten unbrauchbar zu machen. 5.2.6.1.2 Kriterien Die Flasche muss 12 000 Lastwechseln bis zum Prüfdruck (ph) oder 24 000 Lastwechseln bis zum entwickel-ten Höchstdruck (pmax) standhalten, ohne dass ein Versagen durch Bersten oder Undichtigkeit auftritt. 5.2.6.1.3 Zu überwachende und aufzuzeichnende Parameter a) Temperatur der Flasche; b) Anzahl der Lastwechsel, bei denen der obere zyklische Druck erreicht wurde; c) geringster und höchster zyklischer Druck; d) Lastwechselfrequenz; e) verwendetes Prüfmedium: f) Art des Versagens, sofern zutreffend.
