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.
