Scope

Main technical content: The standard specifies the terms and definitions, symbols, types, and basic parameters of liquid hydrogen gas cylinders for automobiles; materials; design; manufacturing; test methods; inspection rules; marking; packaging; transportation; storage; product conformity certificates; product user manuals; batch inspection quality certificates; and usage requirements. It applies to rechargeable welded insulated gas cylinders used as automotive fuel tanks under normal environmental temperatures (–40°C to 60°C), with a storage medium of liquefied hydrogen, a design temperature not exceeding –253°C, a nominal volume of 375L to 1500L, and a nominal working pressure of 0.8MPa to 1.29MPa. It defines the structural types and naming methods of liquid hydrogen gas cylinders for automobiles, clarifies the requirements for performance parameters such as static evaporation rate, vacuum interlayer leakage rate, and leakage/venting gas rate corresponding to various volumes, and sets control requirements for the material properties of cylinder components such as cylinder body materials, steel pipes and fittings, insulation materials, and adsorbent materials. In the design section, it stipulates that the connection between the inner liner and the outer shell should have sufficient strength and specifies the calculation method; it also prescribes requirements for the pipeline system, valves, and accessories, and proposes manufacturing requirements such as welding processes, non-destructive testing, and vacuum leak detection methods for liquid hydrogen gas cylinders for automobiles.
