Product Description
This 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 l for compressed, liquefied and dissolved gases.
NOTE. For the purposes of this standard, the word ―cylinder‖ includes tubes up to 450 l water capacity
This 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, aramid, or other high tensile strength fibre (or a mixture thereof) embedded in a matrix.
This standard is also applicable to composite cylinders without liners.
This 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. The specification does not ad dress the design, fitting and performance of re movable protective sleeves. Where these are fitted they should be considered separately.
