Provides the requirements for periodic inspection and testing and to verify the integrity for further service of hoop-wrapped and fully-wrapped composite transportable gas cylinders with aluminium-alloy steel or non-metallic liners or of linerless construction (Types 2 3 4 and 5) intended for compressed liquefied or dissolved gases under pressure of water capacity from 05 l up to 450 l.

This International Standard specifies the requirements for periodic inspection and testing and to verify the integrity for further service of hoop-wrapped and fully-wrapped composite transportable gas cylinders, with aluminium-alloy, steel or non-metallic liners or of linerless construction (Types 2, 3, 4, and 5), intended for compressed, liquefied or dissolved gases under pressure, of water capacity from 0,5l up to 450l.

This International Standard is written to address the periodic inspection and testing of composite cylinders constructed to ISO11119-1 , ISO11119-2 , and ISO11119-3 standards and can be applied to other composite cylinders designed to comparable standards when authorized by the competent authority.

As far as practicable, this International Standard also can be applied to cylinders of less than 0,5l water capacity.
