CSA/ANSI NGV 5.2-2017 - Vehicle fueling appliances (VFA)
Preface
This is the first edition of CSA/ANSI NGV 5.2, Vehicle fueling appliances (VFA). It supersedes CSA 12.6, Vehicle refuelling appliances. The content of this Standard was developed using the requirements in CSA 12.6, Vehicle refuelling appliances; CSA/ANSI NGV 5.1, Residential fueling appliances; and current code requirements. The CSA NGV 5.2/12.6 technical subcommittee reviewed coverage in CSA 12.6 and CSA/ANSI NGV 5.1 to create this new Standard and create a Standard which would 1) resolve overlapping conflicting requirements; and 2) focus on coverage for vehicle fueling appliances for other than residential applications (VFA). The document is designated CSA/ANSI NGV 5.2 to remove potential confusion in the field with equipment marked as complying with CSA 12.6.Scope
1.1 General This Standard details mechanical, physical, and electrical requirements for a newly manufactured non- residential appliance, referred to as a vehicle fueling appliance (VFA), that compresses natural gas for vehicles and dispenses directly into onboard vehicle storage or delivers to external natural gas storage systems. This Standard applies to appliances that incorporate compression and dispensing in the same appliance. Notes: 1) Residential fueling appliances (RFA) are addressed in CSA NGV 5.1. 2) Devices dedicated only to dispensing fuel into vehicles are addressed in CSA NGV 4.1. 1.2 Application This Standard applies to compressed natural gas vehicle fueling appliances: a) intended for connection to a natural gas supply source; b) for outdoor installation or indoor installation; c) for ambient temperatures not below -40° C (-40°F); d) for nominal voltage not exceeding 480 volts AC; e) certified as a system with temperature compensated pressure limits for delivery of fuel for:- i) direct fueling of vehicles; ii) fueling of vehicles from the systems internal storage; iii) filling of external natural gas storage systems; or iv) any combination of the above.
