This European Standard specifies periodic inspection intervals, procedures for inspection, inspection and testing for transportable refillable composite LPG cylinders with a water capacity from 0,5 l up to and including 150 l.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 or carbon or aramid (or a mixture thereof) embedded in a matrix.This European Standard is also applicable to composite cylinders without liners.
