    Abstract - (Show below) - (Hide below)

    This Standard specifies requirements for design, materials, and performance in service of PN 16 mechanical tapping bands used for the connection of property service pipes to reticulation water mains.

    Scope - (Show below) - (Hide below)

    This Standard specifies requirements for design, materials, and performance in service of PN 16 mechanical tapping bands used for the connection of property service pipes to reticulation water mains.
    This Standard applies to tapping bands, with and without electrical insulation, for mechanical connection to metallic and plastics standard water mains, including polyethylene. The nominal operating temperature range is 0 °C to 40 °C. Tapping bands for use with polyethylene pipes, including other PN ratings and gas applications, are included in AS/NZS 4129.
    Solvent cemented PVC tapping bands are outside the scope of this Standard.
    The nominal size range of tapping bands covered by this Standard is DN 50 to DN 450 with outlet sizes ranging from dn 15 to dn 50, as appropriate to the tapping band size.
    A minimum sampling and testing frequency plan to demonstrate conformity with this Standard is specified in Appendix A.
