Defines the requirements for lightweight refillable fuel tanks intended for the onboard storage of high-pressure compressed gaseous hydrogen or hydrogen blends on land vehicles.

This International Standard specifies the requirements for lightweight refillable fuel tanks intended for the on-board storage of high-pressure compressed gaseous hydrogen or hydrogen blends on land vehicles.

This International Standard is not intended as a specification for fuel tanks used for solid, liquid hydrogen or hybrid cryogenic high-pressure hydrogen storage applications.

This International Standard is applicable for fuel tanks of steel, stainless steel, aluminium or non-metallic construction material, using any design or method of manufacture suitable for its specified service conditions.

This International Standard applies to the following types of fuel tank designs:

• Type 1: metal fuel tanks;

• Type 2: hoop-wrapped composite fuel tanks with a metal liner;

• Type 3: fully wrapped composite fuel tanks with a metal liner;

• Type 4: fully wrapped composite fuel tanks with no metal liner.
