These container assemblies are provided with tanks constructed under the appropriate provisions of the current edition of the Boiler and Pressure Vessel Code of the American Society of Mechanical Engineers (ASME).

1.2 Container assemblies covered by these requirements are those using fuel storage tanks having a water capacity of 4000 gallons (15.14 m3) or less and designed and used only for delivery of fuel in the gaseous phase, but they may also incorporate a liquid take-off in addition to a vapor take-off. This standard does not cover liquid supply to systems or liquid withdrawal from these or any other containers.

1.3 Container assembly installations are intended to be made in accordance with the Liquefied Petroleum Gas Code (National Fire Protection Association); NFPA 58. They are not intended for use in chemical, petrochemical, petroleum, or utility power plants; nor pipeline or marine terminals; nor related storage facilities at such plants or terminals.
