Transportable gas cylinders. Hoop wrapped and fully wrapped carbon composite cylinders and tubes for hydrogen. | Status: Current

1 Scope This document specifies minimum requirements for the materials, design, construction, type 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 (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 × 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.
