The IANGV and affiliated associations are currently working with the United Nations International Standards Organization (ISO) to harmonize natural gas vehicle (NGV) standards worldwide as much as possible.

In the meantime, we recommend the use of our International NGV Standards Gap Analysis, updated in January 2007, as a reference tool for International Standards. The standards listed below are also listed for reference also though IANGV cannot assure that they are current. Visitors are reminded to check with local authorities before relying on the information provided. Corrections are welcomed This e-mail address is being protected from spambots.
