ISO-11119-4: Gas cyl—Refillable composite gas cyl—Design, const and testing—Part 4:Fully wrapped fibre reinforced comp gas cyl up to 150 l w/load-sharing weld metallic line
Full name: Gas cylinders — Refillable composite gas cylinders — Design, construction and testing — Part 4: Fully wrapped fibre reinforced composite gas cylinders up to 150 l with load-sharing welded metallic liners

This part of ISO 11119 specifies requirements for composite gas cylinders with load-sharing welded liners between 0,5 l and 150 l water capacity and a maximum test pressure of 450 bar for the storage and conveyance of compressed or liquefied gases. The cylinders are constructed in the form of a welded stainless steel liner or welded ferritic steel liner or welded aluminium alloy liner and overwrapped with carbon fibre or aramid fibre or glass fibre (or a mixture thereof) in a matrix to provide longitudinal and circumferential reinforcement.

The cylinders in this part of ISO 11119 are type 3 fully wrapped cylinders with a load-sharing metal liner and composite reinforcement on both the cylindrical portion and the dome ends.
Cylinders produced in accordance with this part of ISO 11119 have a minimum design life of 15 years. Cylinders with test pressure of up to 60 bar have an unlimited design life.

This part of ISO 11119 does not address the design, fitting, and performance of removable protective sleeves.

This part of ISO 11119 does not apply to cylinders with seamless liners. For seamless liners, ISO 11119-2 applies.
