NGV Global Industry Workshop – ISO Fuelling Station Standards Update


NGV  Industry Workshop and Forum – Vancouver Convention Centre, Vancouver, Canada, November 29th, 1 pm – 5.30 pm

NGV Global invites natural gas vehicle industry members to an international workshop and forum for an update on ISO “Natural Gas Fuelling Stations for Vehicles” standards currently under development for CNG and LNG. The ISO process combines the expertise of experts from throughout the world to create rigorous standards and remove barriers to global trade.

The workshop will present a summary of both sets of draft standards, including unresolved technical issues, and the forum will solicit feedback from industry members on any gaps or issues they see in the standards.

The workshop will emphasize cross cutting issues between ISO PC 252 and other ISO groups, and also other industry stakeholders. These issues are, for example: oil carryover, gas quality, terminology, temperature and pressure levels (CNG & LNG), methane numbers, odorization, on-board detection, and vehicle & cylinder verification at the time of filling.

NGV Global thanks IMW Industries for their generous support hosting this event.

This event is highly recommended for:

  • Gas industry members
  • OEM vehicle and engine manufacturers
  • Vehicle converters
  • Fuelling station manufacturers
  • Fuelling station owners and operators
  • Compressor manufacturers
  • Dispenser manufacturers
  • Coupling manufacturers
  • Manufacturers of natural gas driers
  • Component suppliers
  • CNG cylinder and LNG tank manufacturers
  • Government agencies and regulators (including UN and regional bodies such as Mercosur & EU)


In January 2010, as a result of a proposal from NGV Global, ISO (International Standards Organisation) sanctioned the development of international standards for CNG and LNG fuelling stations. These standards are being developed under the auspices of Project Committee PC252, and are approximately halfway through their development cycle.

To ensure the proposed standards will meet the needs of all sectors of the industry, the working groups have requested consultation with global industry stakeholders. NGV Global is pleased to facilitate this request and will conduct this workshop and forum to coincide with the next round of PC 252 meetings in Vancouver (November 29-Dec 1)


  • Welcome and Introduction – Brett Jarman, Executive Director, NGV Global
  • A brief history of PC 252 and the timeline for the development cycle of Natural Gas Fuelling Stations for Vehicles standards – Martin Seifert (SVGW, Switzerland), Chairman, ISO PC 252
  • ISO WD 16923 Overview of the CNG Draft Standard – looks at preliminaries, rationale and technical hurdles currently faced by the working group. Followed by Q&A session –  CNG Working Group Leader Diego Goldin (CAGNV, Argentina)
  • ISO WD 16924. Overview of the LNG Draft Standard – looks at preliminaries, rationale and technical hurdles currently faced by the working group. Followed by Q&A session –  LNG Working Group Leader Vaclav Chrz (Chart Industries, Czech Republic)
  • Open Forum.  Determine and prioritise outstanding issues and gaps in the proposed standards. Determine ideal criteria or benchmarks to satisfy industry concerns. Set up ongoing feedback loops if required –  Facilitated by Brett Jarman, NGV Global
  • Wrap up and conclusions

The afternoon may conclude with a preview of an NGV Global Position Paper on Verification of CNG Cylinders and Vehicles at the Point of Refuelling (to be confirmed).
