CAN/CGSB-3.14-2023

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). 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. Note: The requirements for Grade 1 and Grade 2 are derived from the GPA Midstream Association Standard 2140 specifications for HD-5 and commercial propane, respectively. 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 F.7). 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 9). 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. Units of measurement – Quantities and dimensions used in this standard are provided in units from the International System of Units (SI units). This standard expresses the industry standard nominal unit of measurement in North America of “% by volume”. The SI equivalent expression for this unit is % (V/V).
