CEN/TC 23/WG 16 - Fully wrapped composite cylinders

This document specifies minimum requirements for the materials, design, construction, prototype testing and routine manufacturing inspections of fully wrapped composite gas cylinders for compressed, liquefied and dissolved gases.
NOTE 1   For the purposes of this document, the word “cylinder” includes tubes (seamless transportable pressure receptacles of a water capacity exceeding 150 l and of not more than 3 000 l).
This document 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 or aramid (or a mixture thereof) embedded in a matrix.
This document is also applicable to composite cylinders without liners.
This document 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 2   This document does not address the design, fitting and performance of removable protective sleeves. Where these are fitted, they are considered separately.
This document is primarily for compressed, liquefied and dissolved gases other than LPG.
NOTE 3   For dedicated LPG cylinders, see EN 14427.

This document specifies minimum requirements for the materials, design, construction, prototype testing and routine manufacturing inspections of composite gas cylinders and tubes for compressed hydrogen.
NOTE 1   Unless specified in the text, for the purposes of this document, the word "cylinder" includes tubes.
This document applies only to fully wrapped composite cylinders with carbon fibres intended to be permanently mounted in a frame (e.g. bundle or trailer) with a test pressure of not less than 300 bar, with:
-   non-metallic liners or seamless metallic liners;
-   a maximum water capacity of 3 000 l;
-   a maximum working pressure of 1 000 bar;
-   the product of working pressure times water capacity (p × V) not exceeding 1 000 000 bar.l.
NOTE 2   A glass fibre protective layer is sometimes applied to the external surface of the cylinder.

This International Standard specifies the requirements for design, manufacture and testing of cylinders, tubes, and other pressure vessels of steel, stainless steel, aluminium alloys or of non-metallic construction material intended for the stationary storage of gaseous hydrogen of up to a maximum water capacity of 10 000 l and a maximum allowable working pressure not exceeding 110 MPa, of seamless metallic construction (Type 1) or of composite construction (Types 2, 3 and 4) without any non-seamless load sharing metallic components, hereafter referred to as pressure vessels.
For Existing design already qualified for other applications (e.g. transportable applications) follow the requirements of Annex E.
This International Standard is not intended as a specification for pressure vessels used for solid, liquid hydrogen or hybrid cryogenic-high pressure hydrogen storage applications.

This document specifies minimum requirements for the materials, design, construction, prototype testing and routine manufacturing inspections of composite gas cylinders and tubes for compressed hydrogen.
NOTE 1 Unless specified in the text, for the purposes of this document, the word “cylinder” includes tubes.
This document applies to
-   fully wrapped composite cylinders (Type 3 and Type 4)
-   hoop wrapped cylinders (Type 2)
with carbon fibres intended to be permanently mounted in a frame (e.g. bundle or trailer) with a test pressure of not less than 300 bar, with:
— non-metallic liners (for Type 4) or seamless metallic liners (for Type 2 and Type 3),
— a maximum water capacity of 3 000 l
— a maximum working pressure of 1 000 bar.
— the product of working pressure times water capacity (p x V) not exceeding 1 000 000 bar.l.
NOTE 2 A glass fibre protective layer is sometimes applied to the external surface of the cylinder

This document specifies the requirements for the design, manufacture and testing of cylinders, tubes and other pressure vessels of steel, stainless steel, aluminium alloys or of non-metallic construction material. These are intended for the stationary storage of gaseous hydrogen of up to a maximum water capacity of 10 000 l and a maximum allowable working pressure not exceeding 1 100 bar, of seamless metallic construction (Type 1) or of composite construction (Types 2, 3 and 4), hereafter referred to as pressure vessels.
NOTE   Additional requirements with regard to assemblies (manifolded cylinders and tubes and other pressure vessels) are not covered by this document.
This document is not applicable to Type 2 and 3 vessels with welded liners.
This document is not applicable to pressure vessels used for solid, liquid hydrogen or hybrid cryogenic-high pressure hydrogen storage applications.
This document is not applicable to external piping which can be designed according to recognized standards.
