Specifies requirements for welded carbon steel LP Gas fuel vessels of total internal volume not greater than 500 L, and for welded stainless steel LP Gas fuel vessels of total internal volume not greater than 200 L, intended for automotive and marine installations.

This Standard specifies requirements for welded carbon steel LP Gas fuel vessels of total internal volume not greater than 500 L, and for welded stainless steel LP Gas fuel vessels of total internal volume not greater than 200 L, intended for automotive and marine installations.Appendix A specifies additional requirements to allow the supply of subassemblies, consisting of the container shell and the components listed in AS/NZS 1425, for use by an installer without pre-installation tests.NOTES:1 AS/NZS 1425 specifies requirements for the installation of LP Gas fuel vessels for vehicles.2 Users of this Standard are reminded that it has no legal authority in its own right, but acquires legal standing when adopted by government or an authority having jurisdiction, or if specified as part of a commercial contract.
