This Standard specifies requirements for liquefied petroleum gas (LP Gas) products in the liquid phase as supplied for general domestic and industrial fuel purposes, in bulk and into cylinders. The requirements apply to the liquid phase at the point of custody transfer.
This Standard does not include requirements for storage or handling of LP Gas. These are covered in
AS/NZS 1596.
NOTE The composition of the vapour phase is considered to be a direct consequence of the composition of the liquid phase.
1.2 ApplIcation
Product complying with this Standard is safe for heating purposes but is not necessarily fit for purposes in other applications.
This Standard is not intended to apply to LP Gas for supply as a process feedstock. but may provide a basis for such a specification.
