Vehicle fueling appliances (VFA)
This is the third edition of CSA/ANSI NGV 5.2, Vehicle fuelling appliances (VFA) . It supersedes the previous editions published in 2023 and 2017. The following are the major changes to this edition
The first edition of CSA/ANSI NGV 5.2 was developed using the requirements in CSA 12.6, Vehicle refuelling appliances; CSA/ANSI NGV 5.1, Residential fuelling appliances; and current code requirements. The CSA NGV 5.2/12.6 Technical Subcommittee reviewed the coverage in CSA 12.6 and CSA/ANSI NGV 5.1 to create a new Standard that would resolve overlapping conflicting requirements and focus on coverage for vehicle fuelling appliances for other than residential applications. The document was designated CSA/ANSI NGV 5.2 to remove potential confusion in the field with equipment marked as complying with CSA 12.6. This Standard is considered suitable for use for conformity assessment within the stated scope of the Standard. CSA Group acknowledges that the development of this Standard was made possible, in part, by the financial support of Natural Resources Canada. This Standard was prepared by the Subcommittee on Vehicle Refuelling Appliances for Natural Gas Vehicles, under the jurisdiction of the Technical Committee on Natural Gas Transportation and the Strategic Steering Committee on Transportation, and has been formally approved by the Technical Committee. This Standard has been developed in compliance with Standards Council of Canada requirements for National Standards of Canada. It has been published as a National Standard of Canada by CSA Group. This Standard has been approved by the American National Standards Institute (ANSI) as an American National Standard
This Standard details the mechanical, physical, and electrical requirements for a newly manufactured appliance that compresses natural gas for vehicles and dispenses directly into
This Standard applies to appliances that incorporate compression and dispensing in the same appliance. Notes: 1) Residential fuelling appliances are addressed in CSA/ANSI NGV 5.1. 2) Mobile fuelling appliances are addressed in CSA/ANSI NGV 5.3. 3) Devices dedicated only to dispensing fuel into vehicles are addressed in CSA/ANSI NGV 4.1
This Standard applies to all appliances that are
Pressure references All references to "kPa" and "psig" throughout this Standard are to be considered gauge pressures unless otherwise specified.
In the case of conflict between this Standard and federal, national, provincial/territorial, state, or local requirements, the requirements of the authority having jurisdiction take precedence.
The requirements of this Standard are not intended to constrain innovation. When considering fuels, materials, designs, or constructions not specifically dealt with in this Standard, these alternatives may be evaluated as to their ability to yield levels of safety and performance equivalent to those prescribed by this Standard.
"Fuelling" and "refuelling", and "park" and "store" The terms "fuelling" and "refuelling" are used interchangeably in this Standard. The terms "park" and "store" and all derivatives thereof are used interchangeably in this Standard.
In this Standard, "shall" is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the Standard; "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 Standard. 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.
The values given in SI units are the units of record for the purposes of this Standard. The values given in parentheses are for information and comparison only.
