Except as covered in paragraphs (e)(3) (ii) and (iii) of this section, containers shall be in accordance with Table H-32.
Footnote(1) Container type may be increased by increments of 25.
The minimum design pressure of containers shall be 100% of the
container type designation when constructed under 1949 or earlier
editions of the ASME Code (Par. U-68 and U-69). The minimum design
pressure of containers shall be 125% of the container type
designation when constructed under: (1)The 1949 ASME Code (Par. U-200
and U-201), (2) 1950, 1952, 1956, 1959, 1962, 1965, and 1968
(Division 1) editions of the ASME Code, and (3) all editions of the
API-ASME Code.
Footnote(2) Construction of containers under the API-ASME Code is
not authorized after July 1, 1961.

Containers manufactured and maintained under DOT specifications and regulations may be used as fuel containers. When so used they shall conform to all requirements of this paragraph.
All container inlets and outlets except safety relief valves and gaging devices shall be labeled to designate whether they communicate with vapor or liquid space. Labels may be on valves.
Fuel containers for use in industrial trucks (including lift trucks) shall be either DOT containers authorized for LP-Gas service having a minimum service pressure of 240 p.s.i.g. or minimum Container Type 250. Under 1950 and later ASME codes, this means a 312.5-p.s.i.g. design pressure container.
