DESIGN AND cONSTRUCTIONSTANDARDS
(a) LP-Gas fuel cylinders shall be constructed ofsteel or aluminum and shall conform to the appropriateA SME,Department of Transportation (DOT). andTransport Canada (TC) Standards.DOT and TC cylin-ders shall have a minimum service pressure rating of240 psi (16 bar).
NOTE: Newly constructed cylinders used in Canacsa require TCmarkings.Cylindery manuafaciured to TC standards contain rmetricmnarkings. Cylinders used in the United Saates recuire DOT markingsSone cylinders are manufactured and dual marked to allow fillingand usc in hoth counries ie.g..DOT-4BA240—TC4BAM164.(b)LPG fuel cylinders shall be constructed to engagea substantial positioning pin or an equivalent meanstoprovide for intended positioning of the cylinder.(See Fig 1.G.)
(c) LPG fuel cylinders shall be filled (see Table l)by weight only or by either weight or volume.
(d)LPG fuel cylinders. which can be filled by eitherweight or volune.shall have a fixed liquid level gauge.
MARKINGs
Cylinders shall be marked in accordance withNFPA58.
