CAN/CGSB-3.14-2018

This standard 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). NOTE The requirements for Grade 1 are derived from the GPA Midstream Association GPA 2140 HD-5 specification. Grade 2 is adequate for most industrial and domestic uses and may also be suitable for low severity internal combustion engine applications where a high-octane fuel is not required. In view of the maximum sulphur level specified in this standard, fuel conforming to the standard may be unsuitable for spark-ignition motor vehicle engines with emission control technology that includes catalysts (see F7). Users of this standard are advised to take appropriate measures to address health and safety concerns related to the use and handling of propane (see 8.3). The testing and evaluation of a product against this standard may require the use of materials and/or equipment that could be hazardous. This standard does not purport to address all the safety aspects associated with its use. Anyone using this standard has the responsibility to consult the appropriate authorities and to establish appropriate health and safety practices in conjunction with any applicable regulatory requirements prior to its use.
