Compressed natural gas (CNG) fuel storage and delivery systems for road vehicles
This is the fourth edition of CSA/ANSI NGV 6.1, Compressed natural gas (CNG) fuel storage and delivery systems for road vehicles. It supersedes the previous edition published in 2021, 2018, and 2016. The following are the major changes to this edition: 1) streamlined the fire test to make it more user friendly; 2) allowed other component Standards (R110, ISO 15500) to be used on an interim basis to allow current manufacturers to meet this Standard; and 3) clarified requirements for French translations for Canada. The first edition of CSA/ANSI NGV 6.1 was a Recommended Practice that provided a recommended standard practice for vehicle fuel systems. It was written in mandatory language to accommodate its adoption by anyone wishing to do so. The second edition transitioned to a National Standard. 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 Fuel Systems for Natural Gas, 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.

Notes:
In this Standard, "shall" is used to express a requirement, i.e., 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.
