This document does not address the design, fitting, and performance of removable protective sleeves. This document does not apply to cylinders with welded liners. NOTE 1 References to cylinders in this document include composite tubes if appropriate. NOTE 2 ISO 11439 applies to cylinders intended for use as fuel containers on natural gas vehicles and ISO 11623 covers periodic inspection and re-testing of composite cylinders.

ISO 11119-4:2016 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. NOTE 1 1 bar = 105Pa = 105N/m2. 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. ISO 11119-4:2016 does not address the design, fitting, and performance of removable protective sleeves. ISO 11119-4:2016 does not apply to cylinders with seamless liners. For seamless liners, ISO 11119‑2 applies. NOTE 2 ISO 11623 covers periodic inspection and re-testing of composite cylinders.

ISO 11119-1:2012 specifies requirements for composite gas cylinders and tubes between 0,5 l and 450 l water capacity, for the storage and conveyance of compressed or liquefied gases. ISO 11119-1:2012 applies to type 2 hoop wrapped cylinder or tube with a load-sharing metal liner and composite reinforcement on the cylindrical portion only. ISO 11119-1:2012 is limited to cylinders and tubes with composite reinforcement of carbon fibre, aramid fibre or glass fibre (or a mixture thereof) within a matrix or steel wire to provide circumferential reinforcement. Cylinders complying with ISO 11119-1:2012 have a minimum design life of 15 years. ISO 11119-1:2012 does not address the design, fitting, and performance of removable protective sleeves.

ISO 11119-2:2012 specifies requirements for composite gas cylinders and tubes between 0,5 l and 450 l water capacity, for the storage and conveyance of compressed or liquefied gases. ISO 11119-2:2012 applies to type 3 fully wrapped cylinders or tubes with a load-sharing metal liner and composite reinforcement on both the cylindrical portion and the dome ends. ISO 11119-2:2012 is limited to cylinders and tubes with composite reinforcement of carbon fibre, aramid fibre or glass fibre (or a mixture thereof) within a matrix. Cylinders complying with ISO 11119-2:2012 have a minimum design life of 15 years. ISO 11119-2:2012 does not address the design, fitting, and performance of removable protective sleeves. ISO 11119-2:2012 does not apply to cylinders with welded liners.

ISO 11119-3:2013 specifies requirements for composite gas cylinders up to 150 l water capacity and composite tubes above 150 l water capacity and up to 450 l water capacity, for the storage and conveyance of compressed or liquefied gases. The cylinders and tubes in ISO 11119-3:2013 are Type 4 Fully Wrapped Cylinders or Tubes with a non-load sharing liner and composite reinforcement on both the cylindrical portion and the dome ends, and Type 5 Fully Wrapped Cylinders or Tubes without liners (including cylinders without liners manufactured from two parts joined together) and with a test pressure of less than 60 bar. The cylinders are constructed in the form of a disposable mandrel overwrapped with carbon fibre or aramid fibre or glass fibre (or a mixture thereof) in a resin matrix to provide longitudinal and circumferential reinforcement, and in the form of two filament wound shells joined together. Cylinders and tubes manufactured and tested to ISO 11119-3:2013 are not intended to contain toxic, oxidizing or corrosive gases. ISO 11119-3:2013 is limited to cylinders and tubes with composite reinforcement of carbon fibre or aramid fibre or glass fibre (or a mixture thereof) in a matrix. Cylinders and tubes manufactured and tested to ISO 11119-3:2013 have a minimum design life of 15 years. ISO 11119-3:2013 does not address the design, fitting and performance of removable protective sleeves.
