CSA Group Publishes New Edition of CNG Fueling Standard

CSA Group has published a new edition of its standard titled CSA/ANSI NGV 1 – Compressed Natural Gas Vehicle Fueling Connection Devices.

According to the group, this standard is ANSI-accredited and is developed for North America for testing and certification of CNG vehicle fueling nozzles and receptacles.

CSA Group says the initial impetus for the development of CSA NGV 1 was to develop requirements for compatibility of vehicle fueling connection devices, as well as requirements for the development of components specific for use with CNG. A nozzle certified to this standard should be functionally compatible from a safety and performance perspective.

Brandon Grote, global market manager for alternative fuels at Swagelok and chair of CSA Group’s NGV 1 technical subcommittee, says, “CSA NGV 1 was recently updated to include additions and provisions for both the larger-diameter, heavy-duty vehicle refueling nozzles and receptacles and geometry for lower-pressure nozzles and receptacles that may be used for adsorbed natural gas. These improvements help the global natural gas vehicle market meet industry needs for standardized CNG filling connections.”

In addition to the expanded scope stated above, the technical subcommittee reorganized the test fixture tolerance, wear pattern and receptacle figures to make them more user-friendly to users of the standard.

The group says a financial contribution from Natural Resources Canada made the development of CSA NGV 1 and supporting activities possible.
