Scope 

1.1 Application This Code applies to the installation, inspection, repair, and maintenance of the fuel storage and delivery system installed in powered industrial truck applications and vehicles for use with liquefied natural gas (LNG). This includes fuel systems on self-propelled vehicles for the provision of motive power. Federal or provincial regulatory requirements might supersede the requirements of this Code. 

1.2 Exclusions This Code does not apply to a) stationary engines; b) mobile equipment using natural gas as a fuel for other than propulsion; c) electronic components of a fuel management system; d) storage or utilization of natural gas on marine vessels or rail vehicles or transportation by tanker truck; e) recreational all-terrain vehicles; and f) motorcycles. 

1.3 Units of measure The values given in SI units are the units of record for the purposes of this Code. The values given in parentheses are for information and comparison only. Notes: 1) IEEE/ASTM SI 10 or ISO 80000-1 can be used as a guide when converting imperial units to metric units. 2) Where the word “gallon” is used in this Code, it indicates a U.S. gallon equivalent to 3.785 L water capacity. 

1.4 Pressure references All references to “psi” throughout this Code are to be considered gauge pressures, unless otherwise specified. 

1.5 Mandatory and informative provisions In this Code, “shall” is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the Code; “should” is used to express a recommendation or that which is advised but not required; and “may” is used to express an option or that which is permissible within the limits of the Code. Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material. Notes to tables and figures are considered part of the table or figure and may be written as requirements. Annexes are designated normative (mandatory) or informative (non-mandatory) to define their application.
