CEN/TC 23/SC 1/WG 4 - Composite cylinders

This European Standard specifies minimum requirements for the materials, design, construction, prototype testing and routine manufacturing inspections of composite gas cylinders with a water capacity up to and including 450 litres for compressed, liquefied and dissolved gases.
NOTE   For the purposes of this standard, the word "cylinder" includes tubes up to 450 litres water capacity.
This standard is applicable to cylinders that comprise a seamless metal liner reinforced over a substantial part of the parallel length by wound composite fibres of glass, carbon, aramid, or wire.
This standard is not applicable to gas cylinders which are almost totally covered with fibres and commonly called "fully-wrapped" cylinders. For fully-wrapped composite cylinders see prEN 12245.
NOTE   The specification does not address the design, fitting and performance of removable protective sleeves. Where these are fitted they should be considered separately.

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.
