Scope
This National Standard of Canada describes two grades of propane used for fuel purposes. These grades consist
mainly of hydrocarbons containing three carbon atoms.
Grade 1 is intended for use in internal combustion engines and for general industrial and commercial fuel applications.
Grade 1 maintains a minimum octane quality by limiting concentrations of low-octane components (see 6.5…
Objet
La présente Norme nationale du Canada s’applique à deux grades de propane utilisé comme carburant. Ces
grades sont principalement constitués d’hydrocarbures comptant trois atomes de carbone.
Le propane de grade 1 est destiné aux moteurs à combustion interne et peut servir de carburant dans des
applications industrielles et commerciales de nature générale. Il conserve un indice d’octane…
