[Pending Revision]General-purpose natural gas
This Standard sets out the requirements for providing natural gas, suitable for both transportation and general-purpose use and provides the range of gas properties consistent with safe operation of the natural gas appliancesIt specifies general-purpose natural gas, with an emphasis on the safety of the gas for use in natural gas appliances and equipment and for use as fuel in natural gas vehicles. It therefore aims to provide certainty for appliance manufacturers who supply the Australian market.
