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.
