Brief description
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 3000 l - a maximum working pressure of 1000 bar. - the product of working pressure times water capacity (p x V) not exceeding 1000000 bar.l. NOTE 2 A glass fibre protective layer is sometimes applied to the external surface of the cylinder
