This standard contains the suggested minimum design and performance requirements for shop-fabricated, vacuum-insulated cryogenic tanks (vertical and horizontal) intended for aboveground storage of liquid hydrogen.

This standard applies to liquid hydrogen storage tanks with maximum allowable working pressures (MAWP) up to and including 175 psig (1210 kPa). Tanks less than 1000 gal (3785 L) gross volume or greater than 25 000 gal (94 600 L) gross volume and all transportable containers are excluded. Tanks outside these pressure and volume constraints may also follow this standard when agreed upon by the owner/manufacturer and the authority having jurisdiction. This standard does not include operation and installation requirements or emergency response information.
