Propane for fuel purposes

1. SCOPE

1.1 This standard describes two grades of propane used only for fuel purposes. These grades consist mainly of C3

compounds.

1.1.1 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 footnote 6).

Note: The requirements for Grade 1 are derived from the GPA 2140 HD-5 specification.

1.1.2 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 quality fuel is not required.

Note: Propane was referred to as ‘liquefied petroleum gas’ or ‘LPG’ in prior editions of this standard. The terms

‘LPG’, ‘LP Gas’ and ‘Liquefied Petroleum Gas’ are used in North America to refer to various mixtures of C3 and

C4 hydrocarbon compounds.

1.2 Users of this standard are advised to take appropriate measures to address health and safety concerns related to the

use and handling of propane (par. 8.2).

1.3 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. CGSB

neither assumes nor accepts any responsibility for any injury or damage that may occur during or as the result of

tests, wherever performed
