You may need to comply with this standard if you intend to be involved in the construction, design, operation and maintenance of compressed natural gas (CNG) refuelling stations.
CNG refuelling stations can be:
- fast fill, where vehicles are filled in a period of minutes, analogous to liquid refueling
- time fill, where one or (in most cases) a number of vehicles are filled simultaneously over a period of some hours
- a combination of fast fill and time fill.
