|Publication Date:||28 February 2018|
This Standard specifies materials, design, construction, installation, testing and maintenance requirements for steel piping systems for use in conjunction with AS/NZS 4645.1, for the distribution of fuel gas suitable for domestic, commercial or industrial uses, where-
(a) the pressure of the gas is not greater than 1050 kPa and the operating temperature range of the materials is from -30°C to 60°C; and
(b) where the hoop stress level is not greater than 20% of the specified minimum yield stress (SMYS) of the pipe used in that system.
NOTE: The relevant statutory authority may regard this Standard as appropriate for fluids other than fuel gas.
