NGV Industry Standards

Standards Harmonization

NGV Global is committed to and engaged in an ongoing process of harmonizing industry standards. As well as providing consistency between markets, harmonization also removes barriers for industry members looking to export to other countries and regions.

The harmonization process commenced in January 2007 with an ISO sponsored forum in Geneva specifically for the NGV and hydrogen vehicle industries.

ISO Liaison

A key factor of our harmonization work is our liaison status with the International Standards Organization (ISO), as noted in the table below.

NOTES

Category A Liaison: Organizations that make an effective contribution to the work of the technical committee or subcommittee for questions dealt with by this technical committee or subcommittee. Such organizations are given access to all relevant documentation and are invited to meetings. They may nominate experts to participate in a WG/PT.

Category D Liaison: Organizations that make a technical contribution to and participate actively in the work of a working group, maintenance team or project team.

Our liaison status also permits us to initiate ISO standards. NGV Global members can access documentation for this process within the member’s area of this website (login required).

Members interested in the overall ISO process will find details on the standards pages within the login area.

OIML Liaison

NGV Global has liaison status with OIML (ORGANIZATION OF LEGAL METROLOGY INTERNATIONAL) for the OIML CNG Metering Recommendation R 139 – Compressed gaseous fuel measuring systems for vehicles recommendation, originally published in 2007. See our OIML pages for more details (login required).
