AS 4564:2020

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.

purpose natural gas for use in natural gas appliances and equipment, and for use as fuel in natural gas vehicles.
This Standard applies to natural gas that is —
(a) from petroleum, landfill, biogas, coal seam and other sources that provide gas for direct or blended supply on a commercial basis through supply systems serving general purpose customers; and
(b) transported and supplied to users for use in natural gas appliances and equipment conforming to the relevant Standards, including natural gas-powered vehicles, natural gas compressors and refuelling facilities.
General purpose natural gas is also subject to legislative requirements relating to quality and may be subject to contractual requirements and variations. Such variations are not within the scope of this Standard.
NOTE Appendices A, B and C provide further information and guidance on gas properties, additional issues to be considered in contracts, and test methods used to verify conformance.
Gas conforming to this Standard is safe for use as a general-purpose natural gas but is not necessarily fit for purpose in other applications such as a dedicated supply to an industrial user. The Standard is not intended to apply to natural gas for supply as a process feedstock but may provide a basis for such a specification. General purpose natural gas may not be from a dedicated source and may be formed by blending gas from different supplies.
