This standard applies to liquid hydrogen storage tanks with maximum allowable working pressures (MAWP) up to and including 175 psig (1210 kPa).^{1, 2} 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.

¹ kPa shall indicate gauge pressure unless otherwise noted as (kPa, abs) for absolute pressure or (kPa, differential) for differential pressure. All kPa values are rounded off per CGA P-11, Metric Practice Guide for the Compressed Gas Industry [1].

² References are shown by bracketed numbers and are listed in order of appearance in the reference section.
