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 watermains.

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 watermains.It applies to tapping bands, with and without electrical insulation, for mechanical connection to standard watermains, with the exception of tapping bands for polyethylene watermains that are covered in AS/NZS 4129. The nominal operating temperature range is 0°C to 40°C.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 80 to DN 450 with outlet sizes ranging from dn 15 to dn 50, as appropriate to the tapping band size.Methods of demonstrating compliance with this Standard are given in Appendix A.
