    Abstract - (Show below) - (Hide below)

    The intent of this Standard is to provide for the protection of the general public, Gas Distribution Network operating personnel and the environment, and to ensure safe and reliable operation of Gas Distribution Network that reticulate gas to consumers. This Part 3 provides more detailed requirements for design, materials, construction, testing and commissioning of plastic mains and services within a network and is to be used together with Part 1. It covers gas distribution networks covered by Part 1 of this Standard for operating pressures up to 600 kPa.

    Scope - (Show below) - (Hide below)

    This Standard specifies materials, design, construction, installation, testing and maintenance requirements for below ground plastics gas distribution networks and shall be used in conjunction with AS/NZS 4645.1, for the distribution of fuel gas suitable for domestic, commercial or industrial uses, where - (a) plastics gas distribution networks include those constructed from materials including polyamide (PA), polyethylene (PE) and polyvinyl chloride (PVC-HI); and(b) MAOP of the gas distribution network is not greater than 700 kPa except for plastics mains and services with a DN greater than 200 mm where the MAOP is limited to 600 kPa.NOTES:1 The diameter and pressure limitations are to limit potential consequences from failure in those systems.2 Although Standard is restricted to less than 700 kPa, sections of this Standard may be useful as guidance for plastics systems with an MAOP greater than 700 kPa. The relevant statutory authority may regard this Standard as appropriate for other than fuel gas.
